“…Calmon at al. [49] observed a reduction in compressive strength when 10-20% of the cement was replaced by waste glass from windshields. They associated this effect to the cracking of the matrix due to the formation of calcium sulphoaluminate at later ages, caused by the alumina content (5%) in the mixture, introduced by the glass.…”

“…However, the statistical analysis of the data by means of Analysis of Variance (ANOVA) indicated that the use of glass microparticles in replacement of cement contributes to reducing permeability and that this influence is independent of the chemical characteristics of glass microparticles. Jain and Neithalath [32] and Calmon et al [49] studied cement pastes with and without microparticles and found that the glass particles replacement led to smaller porosity. Probably, the permeability improvement was due to the chemical composition and the structure of the noncrystalline silica, which favors the occurrence of a pozzolanic reaction, when the glass is put into contact with calcium hydroxide.…”

Different studies investigate the use of waste glass in Portland cement compounds, either as aggregates or as supplementary cementitious materials. Nevertheless, it seems that there is no consensus about the influence of particle color and size on the behavior of the compounds. This study addresses the influence of cement replacement by 10 and 20% of the colorless and amber soda-lime glass particles sized around 9.5 m on the performance of Portland cement mortars. Results revealed that the partial replacement of cement could contribute to the production of durable mortars in relation to the inhibition of the alkali-aggregate reaction. This effect was more marked with 20% replacement using amber glass. Samples containing glass microparticles were more resistant to corrosion, in particular those made of colorless glass. The use of colorless and amber glass microparticles promoted a reduction in wear resistance.

Abstract. Special concrete is the type of concrete that produced by using waste material or using unusual techniques/method of preparation. Special concrete made with waste material is becoming popular in a construction site. This is because the special concrete is selected due to quality, integrity, economic factor and environmental factor. The waste glass is selected as an additional material to provide a good in compressive strength value. The compressive strength is the importance of mechanical properties of concrete and typically the concrete is sustained and stiffed in compression load. The significant issue to utilize the waste glass from the automotive windscreen is to improve the strength of concrete. The waste glass is crushed to become 5 mm size and recognised as crushed waste glass that be used in concrete as additional material. The main objective of the study is to determine the appropriate percentage of crushed waste glass in concrete grade, 30 in order to enhance the compressive strength. There are four mixes of concrete that contained of crushed waste glass with percentage of 2 %, 4 %, 6 % and 8 % and one control mix with 0 % of crushed waste glass. As the result, crushed waste glass with an additional 4 % in concrete is reported having a higher value of compressive strength in early and mature stage. In addition, if the percentage of crushed glass wastes in concrete increases and it leads to a reduction in the workability of concrete.
