Abstract
In many parts of Nigeria and indeed in Africa 150mm and 225mm hollow sandcrete blocks are generally used for building construction. However information has it that 100mm and 125 mm solid sandcrete blocks are in use in idiroko area of Ogun State Nigeria. Since environmental degradation has been identified as a contributing factor to cases of building collapse, this study aims at examining the hygroscopic properties of 100mm and 125mm solid sandcrete blocks with a view to determining the suitability of the use of these types of blocks for building construction without any fear of collapse of the building taking place. Visits were made to sites where these types of blocks are produced for physical inspection to assess their conformity with block production processes as stipulated in relevant codes and standards. Samples of Sandcrete blocks were collected from block manufacturers and tested for water absorption, volume porosity and moisture content. Control experiment was set up to obtain desirable result when production is done according to laid down procedures. In the course of the study,it was confirmed that the staff of contractors had no formal training in quality control of block production and that mix ratio, and mixing procedures of the constituent materials as well as curing method affected the quality of sandcrete blocks produced.It was also confirmed that the quality of blocks produced by commercial manufacturers does not conform to the required standard in BS 2028 of 1970.
