Abstract :The study was carried to evaluate the level of compliance of commercially manufactured sandcrete blocks in Isoko metropolis of Delta State, Nigeria, to International standards. One hundred and fifty insert ignore into journalissuearticles values(150);, twenty eight insert ignore into journalissuearticles values(28); days old, six insert ignore into journalissuearticles values(6); inch solid sandcrete blocks were collected from fifteen insert ignore into journalissuearticles values(15); major sandcrete block industries within the Isoko metropolis. Ten block samples were randomly selected from each block industry. The compressive strength of selected blocks was tested in accordance to ASTM recommended procedures. In Addition, the physical characteristics insert ignore into journalissuearticles values(specific gravity and sieve analysis); of the fine aggregate used for the sandcrete blocks production were equally analyzed. Results from the compressive strength tests showed that all the sandcrete blocks were substandard, as they fall below the minimum permissible compressive strength valve recommended by Nigeria Industrial Standard insert ignore into journalissuearticles values(NIS-87);. From the results the highest insert ignore into journalissuearticles values(mean); compressive strength ranges from 0.653 Nmm-2 to 1.203 Nmm-2. In addition, the results of the sieve analysis showed that most of the fine aggregate used for the sandcrete blocks production were poorly graded, and did not meet NIS standard for fine aggregate used for sandcrete blocks production. Data obtained from this study will help the government to set up quality control unit within the metropolis, so that sandcrete blocks produced and sold to the public are able to meet international insert ignore into journalissuearticles values(NIS and BS); standards
