In this study, high strength concrete with satuated artificial lightweight aggregate(SLWA) produced by domestic for reducing autogenous shrinkage, which provides additional water to the hydratin cement particles, is applied to be the internal curing. This paper presents the test result of basic property of SLWA and autogenous shrinkage with volumes of SLWA.
This paper reports test to assess the influence of water/solid on the compressive strength of fly ash based alkali activated concrete. According to test results, the strength is influenced by the waste/solid. Also, the appropriate Ms(SiO2/Na2O) rate is thought to be 1.0.
