A cost-reduction of self-compacting concrete incorporating raw rice husk ash

The higher material cost of self-compacting concrete (SCC) as compared to normal vibrated concrete is mainly due to its higher cement content. In order to produce economical SCC, a significant amount of cement should be replaced with cheaper material options, which are commonly found in byproduct...
