Effects of Water Repellency Treated ALC Powder on the Properties of Mortar Mixed with ERCO

발수 처리한 ALC 분말이 유화처리 정제유지류(ERCO) 혼입 모르타르의 품질특성에 미치는 영향

This study was done to resolve the air reduction in mortar when mixed with ERCO. Effects of the water repellent ALC powder due to its particle size and substitution ratio on the cement mortar with ERCO was analyzed. Results showed more water repellent ALC powder ensured more air but did not affect the size of particles. It was determined the compression was caused by more air and water added to achieve the flow. Therefore, substituting with water repellent ALC powder may compensate for the air reduction in mortar with ERCO. Other measures and approaches are needed in order to resolve the reduced strength.
