“…Finer glass particles led to an increase in the reactivity of glass with lime, and hence improved compressive strength and decreased shrinkage. Chen et al (2006) considered the performance of concretes with various waste E-glass particle amounts. The size distribution of glass particle was from 38 to 300l and about 40 % of E-glass particle was less than 150l.…”

The successful completion of the present research would be achieved using ground waste glass (GWG) microparticles in self-consolidating concrete (SCC). Here, the influences of GWG microparticles as cementing material on mechanical and durability response properties of SCC are investigated. The aim of this study is to investigate the hardened mechanical properties, percentage of water absorption, free drying shrinkage, unit weight and Alkali Silica Reaction (ASR) of binary blended concrete with partial replacement of cement by 5, 10, 15, 20, 25 and 30 wt% of GWG microparticles. Besides, slump flow, V-funnel, L-box, J-ring, GTM screen stability, visual stability index (VSI), setting time and air content tests were also performed as workability of fresh concrete indicators. The results show that the workability of fresh concrete was increased by increasing the content of GWG microparticles. The results showed that using GWG microparticles up to maximum replacement of 15 % produces concrete with improved hardened strengths. From the results, when the amount of GWG increased there was a gradual decrease in ASR expansion. Results showed that it is possible to successfully produce SCC with GWG as cementing material in terms of workability, durability and hardened properties.

“…The use of coarse glass was not satisfactory, resulting in marked strength regression and excessive expansion [3][4][5]. However, glass powders with a microscale size distribution produce an improvement in strength and transport properties of mortar and concrete [6][7][8][9]. Research on waste glass as SCM is still rare, whereas the market of glass-composite cement is potentially available.…”

Abstract. Utilization of waste glass in cement is an attractive options because of its pozzolanic behaviour and the market of glass-composite cement is potentially available. The objective of this research is to evaluate the formulation of waste glass as supplementary cementitious material (SCM) by an extreme vertices mixture experiment, in which clinker, waste glass and gypsum proportions are chosen as experimental variables. The composite cements were synthesized by mixing all of powder materials in jar mill. The compressive strength of the composite cement mortars after being cured for 28 days ranges between 229 to 268 kg/cm2. Composite cement mortars exhibit lower compressive strength than ordinary Portland cement (OPC) mortars but is still capable of meeting the SNI 15-7064-2004 standards. The highest compressive strength is obtained by shifting the cement blend composition to the direction of increasing clinker and gypsum proportions as well as reducing glass proportion. The lower compressive strength of composite cement is caused by expansion due to ettringite and ASR gel. Based on the experimental result, the composite cement containing 80% clinker, 15% glass and 5% gypsum has the highest compressive strength. As such, the preliminary technical feasibility of reuse of waste glass as SCM has been confirmed.

“…It is low in shrinkage and water absorption, and it is high in resistance to wear [9]. The using of WG causes the interaction between alkalis in cement and the silica in aggregates which gives silica gel which may be swelled by absorbing water and so the gel volume increases, this swelling generates internal stresses which introduce cracks [11].It was found that the flexural, compressive, and tensile strengths of WG concrete had decreasing tendency with increasing WG ratio [12], also incorporation of 30% glass powder could be done in concrete without any long term effects [13].It was observed a clear improvement in the WG concrete mixes compressive strength , but the workability reduced when the content of WG increased [14]. The pozzolanic influence of WG is more clear at the later age [28 days] in concrete , the optimum % of WG which awards the maximum results of flexural and compressive strengths equal to 20% and using WG powder decreases the ASR expansion [15].…”

“…One of its important contributions is concrete production [5].Because of the alkali-silica reaction (ASR), which causes decrease in durability and also concrete strength, its application is still not common at present time [6]. Glass aggregate is strong but brittle, it has angular shape and relatively smooth texture [7][8][9][10]. It is low in shrinkage and water absorption, and it is high in resistance to wear [9].…”
