Cheah and Ramli (2011) investigated the implementation of wood waste ash as a partial cement replacement material in the production of structural grade concrete and mortar. Elinwa et al. (2008) assessed the fresh concrete properties of self-compacting concrete containing Saw Dust Ash. Elinwa and Mahmoodb (2002)
The consumption of natural resources like sand and stones for concrete production has resulted not only in their scarcity but also in environmental degradation associated with their extraction, and air pollution due to the generated quarry dust as result of the rock crushing. Also, with increase of mining sites in Rwanda, the amount of mine tailings has extremely increased, and their dumping ...

Research highlights Quarry dust (QD) used as partial substitute of sand, and RHA as cement replacement. QD obtained as a by-product from the crushing process of granites. RHA enhanced the hardened mechanical properties of concrete. Minor decline in mechanical properties were observed due to QD inclusion. QD can be a viable substitute to sand, in the presence of RHA to produce HSC.
