  • Essay / Properties of cement mortar incorporating solid waste as fine aggregates: a review

    KI Syed Ahmed Kabeer and Ashok Kumar Vyas studied the performance of cement mortar made with marble powder as fine aggregates. Fine aggregates were replaced with marble powder in steps of 0, 20, 40, 60, 80 and 100%. The characteristic variation in water requirements makes it possible to achieve the required workability of mortar mixtures incorporated into marble 1:3 (A), 1:4 (B), 1:5 (C)) and 1:6 (D) in due to thixotropic nature. marble powder.

They replaced the 10% sand with marble powder to prepare a 1:3 ratio mixture with and without super plasticizer. As a result, they found that a 10% substitution of sand with marble powder provides maximum strength with the same workability. Khyaliya et al. We carried out compressive strength tests to determine the possibility of using marble powder as a replacement for sand in poor mortar. They replaced the sand with marble powder at 25, 50, 75 and 100% by volume. An increase in compressive strength is noted when substituting river sand with marble powder by up to 50%. At a 50% replacement level, the compressive strength increased from 2.84 MPa (control mixture) to 7.04 MPa (50% replacement level). KI Syed Ahmed Kabeer and Ashok Kumar Vyas studied the performance of cement mortar made with marble powder as fine aggregate. Fine aggregates were replaced with marble powder in steps of 0, 20, 40, 60, 80 and 100%. At 20% replacement level, maximum compressive strength was obtained for sand-cement ratio 1:3 (A), 1:4 (B) and 1:5 (C) compared to conventional mortar. On the other hand, for a cement sand ratio of 1:6 (D), substituting up to 60% of the sand with marble powder achieves maximum strength. Khyaliya et al. determined the drying shrinkage of the control and modified mortar mixture at 25 days of exposure conditions. It can be seen from the figure that the drying shrinkage is the same at the end of the exposure time of the control mixture and the mixture modified with marble at a replacement level of 50%. Therefore, cracking will not be a problem when using waste marble powder as a replacement for river sand up to 50%. KI Syed Ahmed Kabeer and Ashok Kumar Vyas carried out drying shrinkage test of cement mortar made with and without marble powder as fine aggregate. In this study, fine aggregates were replaced by marble powder at different substitution levels; 20, 40, 60, 80 and 100%. It was observed from the figure that the drying shrinkage is the same for the control mortar and the mortar at a replacement level of 20%. This is due to the higher specific surface area of ​​marble powder compared to sand. The use of solid waste (stone waste and marble powder) in various forms in cement mortar as a partial replacement for fine aggregates was studied over the following years. This review article has presented a variety of aspects about solid waste (waste stone and marble powder) and their use in mortar, which can possibly be succinct and concluded as follows: Effect of waste stone 1.) Mortar of cement incorporating 25% stone waste as a substitute for river waste. sand has a positive impact on the property of.
