Abstract

Sandcrete blocks comprise of water, natural sand cement. Sandcrete blocks are the building units used in the construction of wall and partitions. Diverse sizes of sandcrete blocks are used to construct free standing walls and building structure with load and non – load bearing units. This research work investigate and compared strength of sandcrete blocks produced with fine aggregate from different source in Owo local government area. The targeted areas within Owo local government are Emure, Ipele and Shagari. Sieve analysis was conducted on the samples and the result revealed that all the samples are good for sandcrete block production. Thirty six sandcrete cubes samples were mould. The mix proportion 1:6 was used. Batching by volume was adopted. Curing was done by full immersion of sandcrete and compressive strength test was carried out on each specimen at 7, 14. 21 and 28 days respectively. The percentage of fine aggregate used in this research was 100% for all samples. The results revealed that sandcrete blocks produced with fine aggregate from Ipele, Shagari and Emure gives compressive strength of 4,15N/MM2, 3.56N/MM2 and 5.48N/MM2 at 28 days respectively. Based on the result of this research work, it is recommended that Emure fine aggregate (sand) is considered as most suitable out of the samples tested for sandcrete blocks production.
