CINA ESTRUCTURAL
CEMENT
Description and Regulatory Compliance
CINA Structural Cement is the result of clinker grinding, plaster and mineral additions in the optimum proportions for
obtaining high initial resistance. The raw materials used and additions by CINA have high quality standards, which are
continuously monitored during the production process. CINA Structural Cement meets the specification of the
international standard ASTM C 1157 as cement Type HE.
Applications





Manufacture of concrete for structural construction.
Development of specific structural, such as those intended for beams, columns, slabs, walls, foundations, among
other types.
Manufacture of concrete requiring high early strength. Premixed concrete production.
Manufacture of concrete for use in prestressed elements and tensioned pos. Manufacture of concrete for
precast production.
Development of building blocks and masonry.
Advantages and Productivity



Increased performance due to its greater resistance.
Allows optimization and reduction in consumption of cement.
Shorter setting reducing the rotation cycle of the formwork.

CINA
* The dosage of CINA Structural Cement should be performed according to the particular mix design requirements
specified for each project, which are considered required concrete properties and quality of raw materials use. The use
and application of CINA cement should be done under the guidelines of the current building techniques applicable
standards and / or specifications of each particular project. In developing specific application of the rules is
recommended: ASTM C 94 "Specification for ready-mix concrete", ASTM C 685 "Standard Specification for Concrete
Made with volumetric dosing and continuous mixing, ACI 318 "Requirements building code for structural concrete“
among others.
