Abstract
The relationship between brinell hardness and compressive strength of lateritic paving tiles compounded with pulverized cow bones (PCB) with cement as a binder was investigated. The study involved production and experimental testing of paving tiles. Empirical models for prediction of Brinell hardness were also developed. Test specimens were produced using laterite, silica sand and PCB, with addition of cement as a binder ranging from 2010% by weight. The relationship between brinell hardness and compressive strength for each level of cement content was carried out using linear regression analysis. Results showed a strong correlation between Brinell hardness and compressive strength for 15% cement composition (R =0.9814) to be maximum. Coefficient of alienation of 35.01%, 13.64% and 76.52% for 20%, 15%, 10% cement content respectively were derived, which shows the proportion of variance not shared among the parameters.
