Abstract
Pervious concrete can be immensely used in the construction of farm structures for irrigation purposes in agriculture. This study evaluated the effects of different brands of Nigerian cement on the properties of pervious concrete. Four different brands of Portland cement; Dangote Falcon(grade 32.5), Elephant Supaset (grade 42.5), Elephant Lafarge (grade 32.5) and Dangote 3*(grade 42.5) were used to produce pervious concrete of mix ratio 1:4 and tests such as compressive strength, permeability and density were tested, the void content was also analyzed. The densities of pervious concrete produced were between 2000 kg/m3 – 1948 kg/m3 , with Elephant Supaset being the densest. All brands produced PC of compressive strength higher than 6 N/mm2 which is the minimum strength requirement in BS 5224 Dangote Falcon cement had the highest compressive strength followed by Elephant Supaset, Elephant Lafarge and Dangote 3* in that order after a 21 day curing period with values 16.39 N/mm2 , 13.97 N/mm2 , 13.54 N/mm2 and 13.11 N/mm2 respectively. Elephant cement PC was most permeable with a 10.1 mm/sec value, followed by Dangote 3* with 9.98 mm/sec then Dangote and Elephant S had 9.89 and 8.46 mm/sec respectively. Density is inversely proportional to porosity and permeability. Elephant Lafarge cement had the highest void content with 20.43% followed by 20.13%, 19.52%, 18.31% respectively for Dangote 3*, Dangote Falcon, Elephant Supaset.
Highlights
The numerous properties of concrete like strength, durability, fire resistance, low maintenance, ease in usage etc. has made it the most widely used construction material on earth

The numerous properties of concrete like strength, durability, fire resistance, low maintenance, ease in usage etc. has made it the most widely used construction material on earth. The numerous properties of concrete like strength, durability, fire resistance, low maintenance, ease in usage etc. Has made it the most widely used construction material on earth. A variety of cement types can be used in the production of concrete but the most common is Portland cement; other types include Portland Pozzolana Cement (PPC) [4], rapid hardening cement [5], Sulphate resistant cement etc. One of the types of cement which only harden by reaction with water is the Portland cement, it forms a water-resistant product from clinker pulverization which involves calcium silicates and calcium sulphate. Portland cement is one of the low-cost materials used in the construction world in the last century due to the widespread availability of its raw materials which is shale and majorly limestone
