Abstract

This paper investigates the strength characteristics of hollow blocks in the Sokoto State metropolis. Five commercial block industries were selected, and soil samples were obtained from each manufacturer and transported to the Civil Engineering Laboratory at Umaru Ali Shinkafi Polytechnic, Sokoto. Compressive strength tests were conducted on the blocks, and particle size distribution tests were conducted on the soil samples. The test results show that the aggregates used are good for block making. The blocks produced were found to be unsuitable for use as either load-bearing or non-load-bearing walls as their strength ranges fall below the minimum values of between 2.5 N/mm2 and 3.45 N/mm2  as recommended by NIS 87:2000. Proper selection of constituent materials and curing were suggested to improve the quality of hollow blocks.
