Characteristic Properties of Pervious Concrete Using Brands of Cement for Hydraulic Structure

The study investigated the characteristics of brands of cement to produced pervious concrete. A Convectional concrete was also produced to serve as control. The study involved the determination of compressive, flexural strength of concrete, permeability, void ratio content and pervious concrete density produced with 0.35 water cement ratio. The pervious concrete cubes with volume 150 x 150 x 150 mm3 and flexural specimen in a standard volume in mm3 were cured for three specific period of (7, 21, and 28days) using 1:4 mixed ratio. The brands of cement used were Dangote falcon 32.5, Dangote 3x grade 42.5, elephant Supaset 42.5 and elephant Lafarge 32.5 N/mm. The slump test carried out and shows that elephant supaset has the least slump values. Compressive strength was determined after 28days of curing and it was carefully observed with Dangote falcon had the highest strength of 16.99N/mm2 , Elephant supaset was second highest with 14.54 N/mm2 , Elephant Lafarge with 14.14N/mm2 and Dangote 3x having 14.14N/mm2 . Elephant supaset (grade 42.5) had highest density with the value 2120.08 kg/m3, the water absorption showed that Dangote 3x (42.5) has affinity for water. It is concluded that elephant supaset is the most workable amongst the grades of concrete and Dangote 3x is the most suitable for plastering rather than casting of concrete. It can also be used as hydraulic structures to cheek floods.
