The various estimates done by a huge number of acclaimed analysts and estimators around the world have indicated a huge declaration of damage that the world will sustain due to the presence of a vast variety of solid waste. Using waste not only dwindle energy utilization, but also helps to preserve the atmosphere. The aim of. this research is to examine the properties of roller-compacted concrete using waste glass powder as a partial substitution of fine aggregate. This research. includes the study of split tensile strength at. 28 days of curing. In this experimental work, 10%, 20% and 30% by weight of fine aggregate was replaced with waste glass powder. A total of 12 number of samples in 4 different mixtures,. in which one control mix.,. three mixes with inclusion of glass powder were prepared having three samples for each concrete mix at 1:1.5:3 mix ratio. According to the research parameters, replacing fine aggregate with glass powder reduces strength with the increase of glass powder replacement percentage. However, it is the best choice where high strength is not needed thus producing a environmental friendly concrete.

INTRODUCTION The solid waste generation in the wold is in billions of metric tons currently and the amount of that waste is supposed to rise and accelerate given the current circumstances. It is estimated that the waste generation around the globe is 1.3 billion metric tons of. municipal solid waste every year and. this amount is expected to hike to about 2.2 billion tons. by 2025[1-3]. The solid waste generation in the developing countries like Pakistan, India etc is not only a threat but a huge menace because of the absence of necessary essentialities, infrastructure, processing units and recycling units to tackle out the waste accumulation. Pakistan produces about 48 million tons of. solid waste a year which has been increasing by 2% each year [4-5]. Pakistan generates about 77,000. tons of solid waste per day especially from the metropolitan regions like Karachi, Faisalabad, Lahore, Islamabad etc. Roller-compacted concrete is a concrete that is compacted by rollers and protects the vibratory roller in its unhardened condition during compaction. Its strength and consistency are extracted from the use of only enough paste volume to cover the aggregate spaces and zero slump water [6]. In the 1980s, roller-compacted concrete was developed for dam construction. It is now widely used for dams, pavements, and the restoration of existing concrete dams. Its processing is a quick method of manufacturing concrete. Roller-compacted concrete's properties are largely determined by the consistency of its materials and compaction. Rollercompacted concrete mix is well compacted when it is sufficiently dry to assist vibratory roller and reasonably wet to facilitate even paste diffusion over mass. Consistency and compaction processes are the key distinctions between traditional and Roller-compacted concrete [7-15]. Slump is negligible in roller-compacted concrete, while workability is present in standard concrete. Quick construction with reduced labor, high load capacity, early strength benefit, low upkeep, no special shapes, and no reinforcing are all advantages of roller-compacted www.irjmets.com. @International Research Journal of Modernization in Engineering, Technology and Science [1287] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:10/October-2021 Impact Factor- 6.752 www.irjmets.com concrete. Roller-compacted concrete has the same materials as traditional concrete, but the blend proportions are the same [16-18]. Concrete is man made substance on earth that is most commonly used. It’s consumption is around 2.3 cubic yards annually for every citizen in the country [19]. The large scale use of concrete in harsh environments is mainly as a result of abundance of its raw materials, it’s proven versatility, mechanical behaviour and improved toughness, as well as the low cost of upkeep over the entire life cycle. It is also accountable for emanation of 10% of. industrial carbon dioxide (CO2) to the atmosphere, along with the essential role of the concrete manufacturing plays in social growth [30-32]. The most important aspect of concrete is the manufacture of cement itself, responsible for just 6 percent of the world's emissions of carbon dioxide [20-21]. Global carbon dioxide discharge have a serious effect on the Earth's temperature, contributing to climate reform and atmospheric warming issues. The consumption of waste not only decreases the cement creation, thereby decreasing the expenditure of electricity, but also helps preserve the environment [26]. Glass is very strong and rough. It can be used as a pozzolanic material if it is ground very coarse, so it is satisfactory as a partial substitution for fine aggregate and cement. Partial substitution will also boost concrete mobility, meaning that it could be used without the use of other superplasticizers to prepare high-strength concrete. Glass will also have a stunning look with a choice of enticing colors to select from. In comparison, recycled glass makes incineration easier, lowers landfills, and eliminates emissions of greenhouse gases from the manufacture of cement. About half a decade now, glass recycling of buildings has been investigated. The glass is observed to have pozzolanic properties when the glass is crumbled to a grain size of less than 75 μm [27-29]. This research work explore the usage of glass waste to substitute fine aggregate and cement in concrete. II. MATERIALS 2.1) Waste Glass Powder: The waste glass was attained from Hyderabad, Sindh. region.. After collecting waste glass, it was crumbled in the Jaw Crusher (as shown in Figure 1) so as to convert it into powder then which was sieved through No. 4 sieve. The sieved powdered glass. (as shown in Figure 2) is used as substitution of fine aggregate in concrete. www.irjmets.com. @International Research Journal of Modernization in Engineering, Technology and Science [1288] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:10/October-2021 Impact Factor- 6.752 www.irjmets.com The chemical composition of waste glass powder incorporated can be evaluated by XRF test (as shown in Table 1). 2.2) Cement: Ordinary Portland cement is a prominent cementitious product utilised in Pakistan's construction industry, hence Lucky Star OPC is chosen for research purposes.

Sieve analysis test was performed as per ASTM C136 [24] to check the suitability of fine aggregate (as shown in Table 4 and Figure 4). www.irjmets.com. @International Research Journal of Modernization in Engineering, Technology and Science [1290] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:10/October-2021 Impact Factor- 6.752 www.irjmets.com III. METHODOLOGY After collecting materials, testing was carried out. Twelve samples have been made to check the Split Tensile. Strength of roller-compacted concrete with inclusion of Waste Glass powder as fine aggregate at 10%, 20% and 30% (as shown in Table). Tensile strength test have been conducted. on 4”diameter 8” height cylinders as per ASTM C496 [22]. Cylinders of roller compacted concrete will be made using compaction hammer on vibration (as shown in Figure 5 & 6 ). Split Tensile strengths are to be checked at 28 days of curing. The ratio is 1:1.5:3 and slump of roller-compacted concrete mixes will be maintained zero. Results will be analyzed and graphs will be plotted to show the strength variation. Based on results, effectiveness Waste Glass is concluded. www.irjmets.com. @International Research Journal of Modernization in Engineering, Technology and Science [1291] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:10/October-2021 Impact Factor- 6.752 www.irjmets.com IV. RESULTS AND DISCUSSION Split Tensile Strength on three cylindrical specimens were executed for all the mixtures with ASTM C496 [22]. An Average. value of three samples was taken as ultimate outcome (as shown in Table 6 and Figure 7). Split Tensile Strength of. Concrete involving substitute of Waste Glass have been decreased due to low silica content in Waste Glass used (as shown in Table 1). However within the waste glass concrete strength increases up-to 20% replacement due to pore filling effect and than decreases due to dilution effect. Results reliability can be shown from R squared value (as shown in Figure 7). V. CONCLUSION In this research work, Tensile Strength of Roller-Compacted. Concrete was conducted at 28 days of curing time period. All the material testings and laboratory investigations have been discussed. Observing all those following conclusions can be drawn: a) Tensile Strength of Concrete using Waste Glass Powder decreases in comparison to control concrete owing to low silica content in Waste Glass, used. b) Within the Waste Glass Powder involved Concrete strength increases up-to 20% of Waste Glass Powder replaced due to pore filling effect. c) After 20% replacement of Waste Glass Powder i.e. at 30%, tensile strength of concrete decreases due to dilution effect of Roller-Compacted concrete. d) The reliability of results obtained can be verified from R squared value (as shown in Figure 7). e) Although Concrete involving Waste Glass Powder as a substitute of. Fine Aggregate reduces strength than the control concrete but it produces environmental friendly concrete by consuming the waste material i.e. Waste Glass. www.irjmets.com. @International Research Journal of Modernization in Engineering, Technology and Science [1292] e-ISSN: 2582-5208 International Research Journal of Modernization in Engineering Technology and Science ( Peer-Reviewed, Open Access, Fully Refereed International Journal ) Volume:03/Issue:10/October-2021 Impact Factor- 6.752 www.irjmets.com VI.
