The study examine the suitability of Ado-Ekiti Metropolis Sand for the production of sandcrete blocks. Five sand samples was collected from five different sand deposit site within the metropolis. The sandy soil was mixed with cement in ratio 1:8 to produce the sandcrete block in compliance with [11]. Test such as specific gravity, sieve analysis, compressive strength, absorption, impact and abrasion were performed on the sandcrete block samples. The result indicates that the sand sample obtained from all the location for grading test were well graded according to NIS specification for Grade L1. The specific gravity ranges from a lower limit of 2.17 and upper limit of 2.76 .the result of the impact varies from a lower limit of 9.6% and upper limit of 18.7%. The result of water absorption varied between 10.4% and 13.9% respectively for all the locations. The Abrasion test varied between 1.73% and 2.56% for all the locations. The compressive strength conducted on the sandcrete blocks for 3,5,7 and 14days ranges between 1.3N/mm2 and 2.7N/mm2 for all the location respectively and the silt test performed on all sample varied between 5% and 8.5%. Based on the test carried out the result obtained shows that Ado-Afao, Ado-Ijan and Ado- Iworoko sand deposit is the most suitable among the five sand deposit identified within the metropolis. It was concluded that those sand deposit site that were found suitable will create supply paucity, increase economic return to the land owners in these community and guide the producer of sandcrete block on the choice of quality material available within the metropolis.
