Applications

1H,1H,2H,2H-Perfluorodecyltriethoxysilane can be used to enhance the waterproof and thermal insulation properties of foamed concrete. To achieve this, an ultrafine fly ash (UFA)-based superhydrophobic composite coating was utilized. Initially, a UFA-based base coating was applied to the foam concrete, significantly improving its waterproofness. The next step involved applying a surface coating modified with a silane coupling agent, which further enhanced the superhydrophobicity of the concrete. The combination of the UFA on the coating surface and the surface asperities created a micro-nanostructure resembling that of a lotus leaf. The superhydrophobic nature of the No. 5 coating was evidenced by a water drop contact angle of 154.34° and a sliding angle of 2.41°, indicating its ability to repel water effectively. Moreover, the composite coating exhibited reduced water absorption ratios of 1.87% and 16.6% at 4 hours and 7 days, respectively, compared to the original foam concrete. This represents a significant reduction of 97% and 75%. Furthermore, the compressive strength and heat conductivity coefficient of the composite coating block remained high even after soaking for 4 hours, exceeding 4.0 MPa and 0.225 W·m-1·K-1, respectively. In conclusion, the UFA-based superhydrophobic composite coating, incorporating 1H,1H,2H,2H-Perfluorodecyltriethoxysilane, offers a simple and cost-effective solution for enhancing the waterproofing capabilities of foam concrete. Its application does not require sophisticated equipment and is suitable for large-scale projects. ²
