Short-term studies on the durability of laterized concrete and laterite-cement mortars
AbstractOne of the most important considerations when any construction material is to be used is that it should withstand the conditions for which it has been designed, without deterioration, over a period of years. As part of our continuing efforts to obtain data on the usefulness of lateritic soils in rural housing and farm structures, this paper reports the findings on the durability of laterized concrete and laterite-cement mortar specimens in terms of permeability and chemical attack on such specimens.The results have shown that the durability of laterized concrete and laterite-cement mortar specimens can be enhanced by the low permeability characteristics of the lateritic soil contents of such specimens. Increases in the values of compressive strength were indicated for corresponding increases in the age of specimens cured in magnesium sulphate solution. On the other hand, on increase in water/cement ratio gave a decrease in the values of compressive strength obtained for specimens cured in magnesium sulphate solution. It is thus clear on a short-term basis that resistance to chemical attack, like the magnesium sulphate solution, is good and produces no detrimental effect.
