The current margin for each particular type of concrete mix should be determined; it may be taken as having the smaller of the values given by (1) or (2). i. 1.64 times the standard deviation of cube tests on at least 100 separate batches of concrete of nominally similar proportions of similar materials and produced over a period not exceeding 12 months by the same Project under similar supervision, but not less than 1/6 of the characteristic strength for concrete of grade 7, 20 or 15, or 3.75 N/sq.mm for concrete of grade 20 or above. ii. 1.64 time the standard deviation of cube tests on at least 40 separate batches of concrete of nominally similar proportions of similar materials and produced over a period exceeding 5 days but not exceeding 6 months by the same Project under similar supervision, but not less than 1/3 of the characteristic strength for concrete of grade 7, 10 or 15, or 7.5 N/sq.mm for concrete of grade 20 or above. Where there are insufficient data to satisfy (1) or (2) above, the margin for the initial mix design should be 2 taken as two-thirds of the characteristic strength for concrete of grade 7, 10 or 15, or 15 N/mm for concrete of grade 20 or above. This margin should be used as the current margin only until sufficient data are available to satisfy (1) or (2) above. However, when the required characteristic strength approaches the maximum possible strength of concrete made with a particular aggregate, a smaller margin but not less than 2 7.5 N/mm may have to be permitted for the initial mix design. At each test no cube strength shall fall below the appropriate minimum specified in the Contractor’s designs. Before commencing the Works the Contractor shall submit to the Engineer for his approval full details of the mixes he proposes to use, with their anticipated average strength, which must be based on the satisfactory Section 11– Employer’s Requirements: Technical Specifications: Civil Engineering Works 11 - 192 TENDER NO. : PC. 35 /NT/ 2013 GENERAL DIRECTORATE OF ELECTRICAL TRANSMISSION PROJECTS MINISTRY OF ELECTRICITY, IRAQ results of these preliminary tests.

Neither the mix proportions nor the source of supply of materials shall be altered without the prior approval of the Engineer except that the Contractor shall adjust the proportions of the mix as required to take account of permitted variations in the materials. Such approval shall be subject to the execution, to the Engineer’s satisfaction, of trial mix procedures set out herein. 10.5.3.3 Ready-mixed concrete Ready-mixed concrete as defined in BS 5328, which batched off the Site, may be used only with the agreement of the Engineer and comply with all requirements of the Contract. The concrete shall be carried in purpose made agitators operating continuously, or truck mixers. The concrete shall be compacted and in its final position within 2 hours of the introduction of cement to the aggregates, unless a longer time is agreed by the Engineer. The time of such introduction shall be recorded on the delivery note together with the weight of the constituents of each mix. When truck-mixed concrete is used, water shall be added under supervision, either at the Site or at the central batching Project, as agreed by the Engineer but in no circumstances shall water be added in transit. Unless otherwise agreed by the Engineer, truck mixer units and their mixing and discharge performance shall comply with the requirements of BS 5328 part 3. 10.5.3.4 Materials a).Cements Normal Portland cement complying with all the requirement of BS 12 shall be used in this project.

The Bidder shall indicate on the schedule C the brand name, manufacture and source of the cement which he proposes to use in the Works and the method of delivery. The Contractor shall not place the order for cement before the Engineer’s approval is obtained. All cement shall be obtained from the same source for any particular part of a structure. The Contractor shall not use cement varying from that used in the preparation of trial mixes until any further trial mixes required by the Engineer have been made and tested and shown to comply with the specification. The cement shall be tested to determine the total alkali content in accordance with ASTM C114-69 (Chemical Analysis of Hydraulic Cement) or BS 4550: Part 2. The equivalent weight of sodium oxide shall be calculated from the formula given in BS 5328 part 4. The equivalent weight of sodium oxide shall not exceed 0.6% of the weight of cement. The above restriction shall be waived if the proposed aggregate is proved without doubt to be non-reactive. The cement shall be delivered to site packed in sealed bags or proper containers, of which there shall be 20 to the ton, bearing the name of the brand and manufacturer and the number of the consignment. The approximate weight of the cement shall be legibly marked on each bag. The Contractor shall make the necessary arrangements for deliveries to be made sufficiently frequently to ensure freshness and in sufficient quantities to ensure that there is no suspension or interruption of the concreting work at any time. The Contractor may use cement delivered in bulk; delivery arrangements shall be to the Engineer’s approval and each delivery must be accompanied by a manufacturer’s test certificate. Each consignment of cement shall be brought to the site in sufficient time to allow any tests to be carried out before the cement is used. Section 11– Employer’s Requirements: Technical Specifications: Civil Engineering Works 11 - 193 TENDER NO. : PC. 35 /NT/ 2013 GENERAL DIRECTORATE OF ELECTRICAL TRANSMISSION PROJECTS MINISTRY OF ELECTRICITY, IRAQ Cement in bags shall be unloaded under cover and stored in a well-ventilated and weatherproof building used exclusively for this purpose.

Cement which is more than 12 weeks old from the date of manufacture shall be retested on site for fineness, setting time, strength and soundness in the presence of the Engineer’s representative and full test reports shall be submitted within 24 hours. b).Sulphate – resisting Portland Cement Sulphate-Resisting is designed to prevent the rapid deterioration of concrete made from Portland cements which occurs in structures exposed to certain types of soils and ground-waters. Portland cements can contain up to 14% of tricalcium aluminate (known as C3A). This compound is attacked by sulphates found in certain types of soils and ground-waters, causing concrete/mortar to deteriorate at an unacceptably rapid rate. The tricalcium aluminate content of Sulphate-Resisting is kept below the maximum level of 3.5% permitted by BS 4027 : 1996 to produce Sulphate -resisting Portland cement”. In accordance with the soil investigation report Especially for underground stricture Sulphate-resisting Portland cement concrete recommended and shall be approved by the Engineer. c).Test certificates and samples All cement shall be certified by the manufacturer as complying with the requirements of the appropriate specification. The Contractor shall, when required by the Engineer, obtain for him the manufacturer’s test certificate for any consignment as soon as possible after delivery.

The aggregates shall be stored at mixer positions in such a manner that intermingling of different sizes and types of aggregates is prevented. The stockpiles are to be protected from rubbish or windblown dust. Heaps of fine aggregate shall be capable of draining freely. Wet fine aggregate shall not be used until, in the opinion of the Engineer, it has drained sufficiently to ensure proper control of the water/cement ratio. g).Sampling and testing The Engineer shall have the right to request the Contractor, at any time, to draw samples of aggregates from stockpiles on the Site or any other location to be indicated by the Engineer. All sampling and testing shall be in accordance with BS 812 or to American standards when no appropriate BS exist. For each new source of aggregate and for each class of aggregate to be used sampling and testing shall be done at the rate of six samples and set of test for each new source and each new class. The Contractor shall allow for the whole range of tests to be carried out. For routine sampling and testing from an approved source the rate shall be sample per 50 cubic meter of aggregate to be used or sample per month whichever is greater. Such testing shall include those tests form BS 812 as are considered useful by the Engineer for comparison with the results of the initial set of tests but the Contractor shall allow for the full range to carried out. Testing is to be carried out at an independent laboratory approved by the Engineer or else on the site in the presence of the Engineer’s h).Water The water used for making concrete, mortar and grout shall be clean, fresh and free from injurious amounts Section 11– Employer’s Requirements: Technical Specifications: Civil Engineering Works 11 - 195 TENDER NO. : PC. 35 /NT/ 2013 GENERAL DIRECTORATE OF ELECTRICAL TRANSMISSION PROJECTS MINISTRY OF ELECTRICITY, IRAQ of soil, vegetable or organic matter or any other substance in suspension or solution.

The minimum cement content and the maximum free water-cement ratio shall be in accordance with BS 8110 and BS 5328. The Contractor’s designs and drawings shall show clearly the characteristic strengths, and permissible deviation proposed for each grade of concrete to be used. The Contractor shall carry out frequent tests to the satisfaction of the Engineer to check the relationship of the strength of concrete cured under site conditions to that cured under laboratory conditions. c).Mixing All concrete except where specifically permitted by the Engineer in writing shall be mixed in weigh batch mixing machines. The machines shall have a large water storage tank with a gauge or that a predetermined quantity of water can be injected direct into the mixer drum. The dry concrete ingredients shall be mixed until a uniform color is obtained after the addition of the water the concrete shall be mixed for a further 2 minutes or until a uniform color is achieved. The total water in the mix shall not exceed the amount used in the trial mix. In computing the quantity of water to be added, due account must be taken of the water contained in the aggregates.

The Contractor shall take all precautions to the satisfaction of the Engineer to protect the concrete from the injurious effects of the elements. d).Workability The concrete shall be of such consistency that it can be readily worked into the corners and angles of the framework and around reinforcement without segregation of the materials or bleeding of free water at the surface. On striking the framework it shall present a face which is uniform, free from honeycombing, surface crazing or excessive dusting, and which shall not, in the opinion of the Engineer, be inferior to the standards laid down in later clauses in this Chapter. In order to satisfy the Engineer that adequate for the requirements of the Specification, the Contractor shall carry out a series of workability tests on the preliminary trial mixes required elsewhere in this Chapter. These tests shall be carried out in accordance with BS 1881, or such other procedure as approved by the Engineer. The samples to be tested shall be obtained from the batches used for the preliminary test cubes. In addition the Contractor shall supply for each of the grades of concrete a section of framework complete with reinforcement fixed in position and generally representative of the sections commonly to be employed in the Works. The capacity of this trial section of formwork shall be at least half a batch of concrete but in any case not less than 1/4 cubic meter. The formwork shall comply with the requirements of this Specification for formwork. The mould shall be filled in the presence of the Engineer with concrete of the same mix and batch from which the preliminary test cubes are made and shall be compacted in the same manner with the same Section 11– Employer’s Requirements: Technical Specifications: Civil Engineering Works 11 - 196 TENDER NO. : PC. 35 /NT/ 2013 GENERAL DIRECTORATE OF ELECTRICAL TRANSMISSION PROJECTS MINISTRY OF ELECTRICITY, IRAQ equipment as are proposed for the Works. This procedure shall, if necessary, be repeated with modified mixes until the appearance of the concrete after striking the mould is acceptable to the Engineer, after which it shall be used as the standard for that grade. When specific workability is called for a check it shall be maintained by measuring slump at the rate of one test for each 10 cubic meters of concrete or three tests for each day of concreting. e).Transportation The concrete shall be discharged from the mixer and transported to the Works by means that shall be approved by the Engineer and which shall prevent adulteration, segregation or loss of ingredients, and ensure that the concrete is of the required workability at the point and time of placing.
