| Title |
An Experimental Study on the Strength Properties of the High-Strength Lightweight Concrete with Admixture |
| Abstract |
The purpose of this study is to put to practical use the economical high-strength lightweight concrete mixed with domestic materials, the natural zeolite and mud stone, abundant in domestic instead of imported 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% respectively at optimum replacement rate. |
