Effect of Nano Calcium Hydroxide Coating in Fire Protection in Buildings

Abstract:

Fire hazards in buildings pose a critical challenge, necessitating effective fire protection measures. This study evaluates the potential of nano-calcium hydroxide (NCH) as an additive in fire-resistant paints. Laboratory experiments were conducted following the ASTM E119 standard, testing paint formulations with 1% and 3% NCH. Thermal resistance, protective performance, and economic feasibility were analyzed. Results indicate that NCH-modified paints significantly enhance fire resistance compared to conventional coatings, offering a promising solution for improved fire protection in construction.
