Optimal Mixing Ratios of Silica and Hybrid Resin with Epoxy Resin for Concrete Floor Surface Covering

Epoxy resins, which are currently used as floor-finishing materials in underground parking lots, have many disadvantages, such as peeling, decreased bond strength under wet conditions, low impact resistance, poor film rigidity, susceptibility to corrosion, and environmental unfriendliness. Hence, in this study, an attempt is made to determine the optimal mixing ratios of silica with a silane coupling agent for use as cover materials for concrete floors. Accordingly, experiments were carried out to determine the viability of hybrid finishing materials for use on floors, with 3-glycidoxypropyltrimethoxysilane as the silane coupling agent. Based on the results of adhesion strength, impact resistance, flexural strength, compressive strength, and length change tests, the optimal silica/silane mixing ratio (mass ratio) was found to be 1∶1.75.
