Abstract

This study mainly investigated the effect of seawater as mixing and curing water on the split tensile strength of type I concrete with fly ash addition. A total of 135cylindrical specimens (100mm x200mm) were produced and divided into five groups that were designated as NN, Ns, SS, SN, and SA wherein N stands for normal stands for normal water, S for seawater, and A for air. The first letter corresponds to the mixing water used while the second letter denotes the curing done either in normal water, seawater or in the air. Fly ash was used to partially replace cement at )5, and 10%, and 20% by mass of cement. The specimens were cured for 7, 28, and 90 days and subjected to split tension test afterwards. Statistical analysis of the results showed that the split tensile strength of concrete with seawater had no significant difference from that of concrete mixed and cured in normal water. The optimum strength was obtained at 105 fly ash addition and 90 days curing period. Experimental results and statistical analysis of this study revealed that with the addition of fly ash, seawater could be suitably used as mixing and curing water in concrete.
