This study investigated the effects of using different mixing fluid samples, potable water, fermented locust beans and sewage, on the strength properties of a self-healing concrete. The physicochemical characteristics of the mixing fluid samples were determined before investigating their effects on the strength development of the resulting concrete samples. The strength parameters investigated comprised of the compressive strength, split tensile strength and flexural strength. It was found that for each of the concrete samples cured for 3, 7, 14, 21 and 28 days, the samples produced with fermented locust beans had the highest compressive, split tensile and flexural strength values, followed by those produced with sewage, while the concrete made with potable water had the least strengths for the Grade 20 concrete samples produced. The activities of the bacteria in the mixing water samples containing fermented locus beans and sewage, aside having the potential to seal cracks that develop within the concrete, also increased the strength properties of the resulting concrete.
