.0.1 As society places a great emphasis on fire prevention and disaster reduction, especially in public buildings with high pedestrian traffic, indoor fire prevention and disaster reduction has become a top priority. Consequently, the Ministry of Construction and the Fire Department have imposed higher requirements for the fire resistance ratings of indoor decorative materials. Ordinary water-resistant putty with paint coatings only meets the B级 fire resistance rating, which does not fully comply with the fire resistance requirements. In contrast, natural stone powder is a non-combustible material, and its finished wall decoration can achieve an A1 fire resistance rating, significantly enhancing the fire resistance and ensuring the safety of people's lives.
10.0.2 Natural stone powder construction can be carried out in damp environments without requiring a dry base. Taking the commercial building project of Beijing's Fuqian Zhongjie commercial financial district as an example, the 180,000 square meter commercial building was structurally completed by the end of February, with an indoor renovation deadline set for the end of May. Due to the tight schedule, the basement was quite damp. If the traditional construction method of using putty and paint was employed, the basement walls and ceiling would need to dry before proceeding, which would undoubtedly delay the entire project. By utilizing the natural stone powder construction method, the need to consider environmental dampness is eliminated, significantly accelerating the construction timeline.
10.03 Natural stone powder utilizes coarse aggregates as the base leveling layer, offering high strength and excellent durability. Coupled with the stone powder's inherent high strength, the completed construction typically incurs minimal maintenance costs, with a lifespan of around 5 to 10 years. Even if renovation is needed, it does not require the removal of the base layer like putty coatings do; the stone powder application process only necessitates a surface treatment, without the need to remove the base.
