Experimental data on the compressive and flexural strength of lateritic paving tiles compounded with pulverized cow bone

This article presents the data of the bulk density, compressive strength and flexural strength of lateritic paving tiles compounded with pulverized cow bones (PCB) as reinforcement, the data set are presented in three categories. Category A involves the mixture of laterite and PCB, category B involves the mixture of sharp sand and PCB, lastly, category C involves the mixture of laterite, sharp sand and PCB. The paving tiles were made using the casting method in a 200 × 100 × 60 mm mould, using 20, 15, 10% wt. Portland cement as a binder and cured for 28 days in a curing tank. The data provided will give useful information for predicting the mechanical properties of paving tiles at different PCB constituent percentage.

Data description
The data provided contains the information on the bulk density, compressive strength and flexural strength of PCB reinforced lateritic tiles, with 20, 15 and 10% Portland cement addition as a binder.   Tables 1-3 shows the mechanical properties of category A paving tiles with 20, 15 and 10% cement addition respectively and mixture of PCB with laterite, Tables 4-6 shows the mechanical properties of category B paving tiles, with 20, 15 and 10% cement addition respectively and mixture of PCB with sharp sand. Tables 7-9 shows the mechanical properties of category C paving tiles with 20, 15, 10% cement addition respectively and mixture of PCB, sharp sand and laterite.   Fig. 1 shows a typical lateritic paving tile produced. Finally, Figs. 2 -4 shows the performance of the paving tiles at different cement composition.

Experimental Design, Materials and Methods
The pulverized cow bones (PCB) used in this research study consist of waste femurs, scapulars and ribs of cow procured from an abattoir in Ilorin, Nigeria. They were washed and sundried for 4 weeks, to reduce the moisture content and eliminate the organic matter in the marrows of the bones. Thereafter, they were crushed and pulverized using a laboratory ball mill. The properties of other materials such as lateritic soil and sharp sand used are same as used in [1] and were carried out in accordance with the appropriate standards of American society for test and materials standard (ASTM). The pulverized cow bones were mixed with the lateritic soil and sharp sand. Cement satisfying the requirements of ASTM C150/C150M [2] was used as binder in various proportions. Percentage composition of cement was chosen, based on literature review, where researchers [ 3 , 4 ] have observed that percentage addition of cement above 20%, will not further improve the mechanical properties of tiles and will be of less economic importance. Therefore, the mixing ratios are indicated in Tables 1-9 .
Each paving tile was produced by adopting the method used by Aweda et al., [1] and ASTM C6 85/C6 85M [5] . universal tensile machine FS50AT was used in carrying out the compressive and flexural strength of the paving tiles, following ASTM standards [ 6 , 7 ] respectively. Bulk density was carried out in accordance with ASTM C948 [8] . The paving tiles were curred in a curing tank for 28 days.
