Abstract

This study included the experimental production and investigation of the mechanical
properties of paving tiles produced from a mixture of laterite, silica sand, pulverized cow bones,
and cement. Empirical models of compressive and flexural strength were also developed and
herein presented for the paving tiles. The maximum compressive strength of the paving tiles were
obtained for 20, 15, and 10% cement content as 5.05, 5.05 and 3.08 MPa, while the maximum
flexural strength for similar values of cement content were obtained as 1.83, 1.21 and 0.26 MPa
respectively. The results indicate that there was no noticeable difference in the values of the
compressive strength at 20 and 15% cement content, while a sharp reduction of the mechanical
properties was experienced as the cement content reduces from 15 to 10%. Recommended
composition for paving tiles with pulverized cow bones composite is cement, 15%; pulverized cow
bones, 30%; laterite 35% and silica sand, 20% respectively. Sustainable production of paving tiles
and a sustainable environment can, therefore, be enhanced by replacing granite constituent with
waste cow bones, which can easily be replicated by the empirical models herein developed.
