Abstract
Evaluation of Sulphate Resistance Effects of Glass Powder as A Supllementary Cementitious Material on the Performance of High Strength Mortar
Highlights
Concrete and mortar are the most widely used materials in construction all over the world
Replacement of silica fume decreased the workability of fresh mortar, glass powder increased it
Comparisons revealed that the type of glass powder has no effect on the workability, while the amount of glass powder replaced is efficient; increased workability of mortars by replacing the glass powder is because of its particle surface
Summary
Concrete and mortar are the most widely used materials in construction all over the world. In the last few years, a growing appeal in using waste materials as a replacement of part of aggregates and/or cement in mortar and concrete productions has been seen. Using these kinds of objects as a part of cement replacement provides some benefits to its microstructure and performance, and it gives an opportunity to reduce the amount of cement used and decrease the final cost of concrete manufacturing. Widespread availability of glass makes it cheaper and easier to produce when compared to other pozzolanic admixtures This reality motivated lots of researchers to investigate the possibility of using waste glass as a natural pozzolan and study the effects of using waste glass in concrete, as a cement replacement.
