Abstract
Quality and standardization of all construction materials are of paramount importance and serves as a yard sticks for measurement reflecting the level of development attained by a nation. Sandcrete blocks are construction materials which have gained wide acceptance and used in the construction industries because of the many characteristics properties attached to them. In this research the study enhanced on the compressive strength of hollow sandcrete block. The test was done in accordance with the British Standard 2028(1968), while grain size distribution analysis was conducted on the sand aggregate and crushing stone used which is suitable for block making. Compressive strength test was carried out on the sandcrete block for each percentage of replacement on 7, 14 and 28days. Result of the experiment shows that the inclusion of crushing stone in the sand cement enhances the compressive strength of sandcrete block. Sandcrete block made with (1:8) mix proportion using 20% granite fine replacement give optimum compressive strength of 6.58N/mm². While the block produced using 15% has 5.77N/mm², control has 4.41N/mm², 5% has 4.39N/mm² and 10% has 4.04N/mm². Standardization of block manufacturing process and strict supervision of the manufacturer by the council for the regulation of engineering practice in Nigeria were recommended as measures to improve the qualities of sandcrete blocks. Key Words: Sandcrete blocks, Compressive strength, Construction, Standardization.
