Abstract:
The splitting tensile strengths of seven structural lightweight concretes containing natural sand fines are reported. This paper is third in a series regarding the partial or com-plete replacement of lightweight fines with sand. The test results show equal splitting strengths for all continuously moist cured lightweight and normal weight concretes when the compressive strengths were equal. However, the splitting strengths of the lightweight concretes were generally reduced when the cylinders were allowed to dry before testing. The use of sand fines minimized this strength reduction.
