COMPRESSIVE STRENGTH DEVELOPMENT OF BRICKS MADE FROM MUDDY CLAY AND PORTLAND CEMENT MIXTURE AS A BUILDING COMPONENTS/MATERIALS IN SOKOTO STATE-NIGERIAAbdullahi Abubakar
This project is experimental on the use of muddy clay and Portland cement as building components/materials in the production of bricks. The muddy clay samples were obtained from 30m depth below the ground level. A total number of six (6) cubes were cast; three (3) cubes each were cast for muddy clay and Portland cement, and ordinary muddy clay respectively using molds sizes of 150mm x 150mm x 150mm. The batching used was by volume using mix ratio 1:4, and 500ml of water was added to the mortar to form workability. The cubes were cured for 7 days; 14 days and 21 days, and the compressive strength tests were carried out after every curing age. The average compressive strength for muddy clay and muddy clay mixed with Portland cement of the same mix ratio of 1:4 was 20.40N/mm2 and 42.50N/mm2 respectively.Therefore, it was recommended that 100% muddy clay should not be used for bricks production due to low compressive strength observed during crushing. However, 90% muddy clay with 10% cement replacement is recommended in the production of bricks as this may reduce the cost of building.
