This paper constructs linear regression models for estimating the compressive strength (CS) of rice husk ash (RHA)- blended concrete. The conventional multiple linear regression model and multivariate power function-based model are employed. Experimental results show that the performance of the latter is better than that of the former. The multivariate power function-based regression model can achieve good prediction results with a mean absolute percentage error of 14%.
