description: Concrete is basically a mixture of two components: aggregates and paste. The paste, comprised of Portland  cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the  paste hardens because of the chemical reaction of the cement and water. In our society today some of the cement  brands that are being sold are not up to standard and this may be traced to negligence on the part of the  manufacturers by paying very little attention to the quality and also the regulatory body does not put strict  measures to enforce the required standard. This problem has led to the production of poor quality concrete that  increases the risk of collapse of building structures. This research determined the cement brands that have the  highest compressive strength to enhance the quality and durability of the structures being built in the country.  Different brands of Portland cement were used to produce concrete varying with1:2:4 and 1:3:6 mix ratio  respectively with a curing date of 3, 7, 14, 21, and 28 days respectively. No additive was used in any of the mix.  The tests carried out include slump test at its fresh state while compressive strength was carried out for the  hardened concrete, also the vicat test was carried out on the cement brands to determine the setting time.  Compressive strength at 28 days showed that Dangote 3X cement produced 25.27N/mm2, Ibeto cement 38.89  N/mm2, Purechem cement 24.58 N/mm2, Unichem cement 21.16 N/mm2 and Elephant cement 27.9 N/mm2 for  1:2:4 mix ratio respectively. For 1:3:6 mix ratio at 28 days Dangote cement produced 18.89 N/mm2, Ibeto  cement 22.07 N/mm2, Purechem cement 11.63 N/mm2,Unichem cement 15.86 N/mm2 and Elephant cement  16.71 N/mm2 respectively. The study concluded that Ibeto cement has the highest strength at 28 days for 1:2:4  and 1:3:6 mix ratios respectively
