Abstract

Shelter has been considered as the basic physiological need of a man after food and clothing. The use of stabilized earth soil as construction materials have solved and sustained the housing need of most communities because of its affordability prior to the use of the recent sandcrete block work in our modern construction technology. The research work aimed at collecting and running test samples of red earth soils at minimum of five different location i.e. one per state in the south eastern geopolitical zone of Nigeria, to carry out comparative analysis of stabilized red earth soil blocks and sancrete blocks’ strength in the each of the five states of south east as materials for walls in housing construction. The test samples were mixed with ordinary Portland cement and water at stated proportion, moulded and cured for fourteen (14) days. The weight, force and compressive strength of each of these blocks were tested at seven (7) days, fourteen (14) days, twenty one (21) days and twenty-eight (28) days. This is to ascertain the rate at which they gain strength and their ultimate strength in twenty-eight (28) days. The test sampled crushed at standard organization of Nigeria (SON) workshop laboratory at Enugu Office. The result of the compressive strength shows that all the tested samples attained above 1.50N/mm² at twenty-eight (28) days but varies with the selected collection sample location. The graph/histogram of their respective weight, force and strength were plotted against period of gaining strength. The result also shows that the stabilized earth blocks with mix proportion of 1:12 yield twice the quantity of blocks compared to solid sandcrete blocks (SSB). The strength of the stabilized earth blocks (STEB) compared favourably to solid sancrete blocks (SSB) and can be used as substitute for housing construction for low income group in the area.
