An Experimental Study on the Quality Estimation of the Mortar using High-Quality Recycled Sand Producted from the Manufacturing System by Wet Gravity Separation

습식비중분리시스템에서 생산된 고품질 순환모래를 사용한 모르타르의 품질평가에 관한 실험적 연구

This study was to execute the experiment for analyzing the quality characteristics of mortar by type of recycled sand by using the recycled sand produced by the manufacturing system by wet gravity separation in order to develop the removal device of impurities for the production of high-quality recycled sand. As a result, this study has sown that the mortar using the high-quality recycled sand through the manufacturing system by wet gravity separation in the fluidity property, strength property, and shrinkage property largely, compared with the mortar using low-quality recycled sand that not passed the device of sand flux. There was a tendency similar to the plane mortar. In conclusion, it was considered as various quality performances of the recycled sand were improved through the production stage of prototype.
