dc.description.abstractThe construction industry in Nigeria is presently operating at a low ebb due mainly to the high cost of construction materials. The use of local materials has been advocated as a step towards solving this problem. This paper considered the use of sawdust ash (SDA) as a partial replacement of cement in laterized concrete.Compressive strength tests of samples made from mix proportions 1:1.5: 3,1 :2:4 and 1:3:6 at various curing ages (7,14,21 and 28 days) for varying SDA content (0,5,10,15,20 and 25%) but at constant water/cement SDA ratio for each mix proportion were considered. It was found that the addition of SDA decreases the strength. The rate of gain of strength, however, was more rapid at curing ages of 21 and 28 days, especially in the mixtures with high percentages of SDA. Strength development was also found to be higher for mixes with lower aggregate/cement ratios than for those with higher ratios.en_US
