Effect of aggregate type on linear thermal expansion of self-consolidating concrete at elevated temperatures

Effect of aggregate type on linear thermal expansion of self-consolidating concrete at elevated temperatures

In this study, the effects of aggregate type on the coefficient of thermal expansion of self-consolidating concrete (SCC) produced with normal and lightweight (porous) aggregate (SCLC) were investigated. In experiments, three aggregate types, gravel, volcanic tuff, and diatomite, were used. Differen...
