The strength and durability of fly ash and quarry dust

Jan 01, 2020· The experimental test result of 30% of fly ash with 30% of quarry dust shows that the higher split tensile strength is 1.75 MPa at 28 days with the w/b ratio of 0.4. Further, the addition content of fly ash in Portland cement there is a decreasing trend was noted in the case of F15-F16 mixes.

gives additional benefit to concrete. Quarry dust is known to increase the strength of concrete over concrete made with equal quantities of river sand, but it causes a reduction in the workability of concrete. When examining the above qualities of fly ash and quarry dust it becomes apparent that if both are used together, the

Mechanical properties of self-compacting concrete

Jan 01, 2012· Highlights Silica fume (SF) and fly ash (FA) are normally used in Self compacting concrete (SCC). Since these materials are costly, SCC was developed utilizing a cheap waste material, namely quarry dust powder (QDP). Mechanical properties of SCC with QDP were better than those of SCC with SF or FA. The use of QDP in SCC resulted in cost saving and the utilization of waste materials.
