Utilization of RHA as an Admixture in High-Strength Concrete. The 7-day, 28-day and 91 day compressive strengths of the RHA were higher than those of the control concrete with-out RHA and also the dosage of super plasti-cizer in concrete increased as the ash content of the cementing material increased. Also, ,

As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation will likely improve the efficiency of water reducers. In general, air entrainment will not be affected, nor will viscosity-modifying admixtures.
Abstract. For over two decades, rice-husk-ash has been discovered to be a highly reactive pozzolana and has been used to substitute a portion of the cement content in concrete mix in order to reduce the cost of concrete manufacture and environmental hazards posed by rice-husk in rice producing areas.

The addition of superplasticizers with mineral admixtures like fly ash, silica fume etc. to concrete imparts a high performance and workability to it, even at very small water cement ratios. But to get the maximum benefit from this amalgamation of concrete and admixtures, the incompatibility issues between these two need to be studied.
