Abstract:
The research was carried out to determine the effect of different brands of cement on the strength of payers. Stone dust plus Cement A (4:1), stone dust plus Cement (B) (4:1), stone dust plus Cement (C) (4:1), stone dust plus pure Cement (D) (4:1). sharp sand plus Cement (A), sharp sand plus Cement(B) (4:1), sharp sand plus Cement (C) (4:1), sharp sand plus Cement (D) (4:1), formed 8 treatment and were replicated five times. The pavers were analyzed for compressive strength at the materials testing laboratory, Materials Testing Laboratory, Ministry of Works and Transport, Oyo State Secretariat, Ibadan. The data collected were subjected to analysis of variance (ANOVA) and Duncan Multiple Range Test (DMRT) was used to separate treatment means. The result shown that Treatment C (stone dust and Dangote cement), G (sharp sand and Dangote cement), were not significantly different with respect to compressive strength. Treatment B (stone dust plus Diamond cement), produce the least value of (133 KN), while Treatment C (sharp sand and Dangote cement) has the highest value (285 KN) which agrees with recommended standard of pavers of 150-300 Kilo Newton by the Nigerian Standard Organization (N.S.O). Also, the cost of production of pavers produced with stone dust is costly than pavers produced with sharp sand. Cement (C), Cement (A) and Cement (B) produced very neat and strong products while Cement (D) does not produce good finished product.
