Application of Residual Rice Husk Ash from Vietnam as a Supplementary Cementitious Material in Concrete

Abstract:

The residual RHA from Vietnam is used to test the likely application in cement and concrete. The characteristics, quality and influence of RHA on the quality of concrete are investigated in this investigation. The workability, strength and durability of concrete added with ground RHA satisfy with the relevant standards and requirements. It indicates that the ground RHA in this study can be used as a good supplementary cementious material. Therefore, it is possible to obtain RHA concrete with comparable properties than those of the control specimen (without RHA) with a lower consumption of cement, thus reducing the CO2 emissions during the production of cement and the environmental and disposal problem of the ash can also be diminished. Moreover, while the results will be able to substantiate the viability of application of RHA in concrete industry under the prevailing conditions in Vietnam, they are also expected to be especially useful for future studies on RHA in a specific condition in this country.
