The test results show significant differences in liquefaction characteristics for coral sand and quartz sand. A unique relationship between deviatoric strain amplitude and excess pore water pressure ratio (R u) can be established regardless of cyclic stress paths. The termed cyclic strain path is introduced to describe the generation features ...
Later river sand is replaced by quartz sand at various percentages of 25, 50, 75 and and the tests were carried out on casted specimens . Samples of concrete with OPC are casted at the same w/c ratio as alkaline-binder ratio and are considered as trail mixes to compare the results with AAC concrete.
