소수성 용액이 혼합된 CAC 혼합 모르타르의 배합비에 따른 표면 특성과 소수성에 관한 연구

초록

This study investigated the effects of incorporating hydrophobic admixtures into mortar, replacing Ordinary Portland Cement (OPC) with Calcium Aluminate Cement (CAC), to enhance the durability of cement-based composites. Results showed that while the addition of hydrophobic admixtures significantly improved the hydrophobicity of the mortar, it also led to a decrease in mechanical strength. Regression analysis was conducted to quantitatively determine the correlation between the dosage of hydrophobic admixtures and the mechanical properties of the mortar, revealing a decreasing trend in strength with increasing admixture dosage. Although the relationship between surface roughness and hydrophobicity was explored, a clear correlation was not found. This study provides fundamental data for determining the optimal dosage and mix proportion of hydrophobic admixtures and can be used as a reference for improving the performance of mortar.
