BRAZILIAN TENSILE-STRENGTH TEST OF LIGHTLY CEMENTED SAND

Tensile stress - tensile strain relationships for lightly cemented san d specimens obtained by conducting Brazilian tensile strength tests ha ve been presented. The tensile strain measurement was done by using an optical image analysis technique. In addition to the tensile strength tests, some unconfined compression tests on sand specimens with varyi ng cement contents were also performed. Based on the results of the ab ove tests, a nondimensional tensile stress - tensile strain relationsh ip has been presented. Also the variation of the tensile and compressi ve strength and strain ratios with varying cement contents have been d iscussed.
