The High-Strengthening of Concrete with Admixture - On the Artificial Lightweight Aggregate Concrete-
초록
The purpose of this study is to put to practical use the economical high-strength lightweight concrete manufactured by domestic materials, through the analysis on the properties of lightweight concrete with the natural zeolite and mud stone abundant in domestic and compare them with those with silica fume. As a result, it was possible to gain proper workability in the lightweight concrete with admixtures through using the superplasticizer. the optimum replacement rate of zeolite and mud stone powder is respectively 5~10%, 10~15% on unit-cement amount. The strength development rate for plain concrete is 27%, 18% at optimum replacement rate.
