Core Viewpoint - The Chinese building materials industry has achieved full coverage of carbon emission accounting in key areas for the first time, showcasing innovative green building materials that enhance living quality [1]. Group 1: Innovative Building Materials - A special ceramic plate has been developed with high strength, excellent translucency, and a smooth glaze, making it resistant to breakage even when dropped from nearly one meter [2]. - A remarkable fire-resistant glass consists of three layers, with two layers of special fire-resistant gel in between, which successfully withstands temperatures exceeding 1000°C while maintaining a surface temperature of only 68°C [3][4]. - The fire-resistant glass can provide over one hour of escape time during a fire in high-rise buildings due to its unique structure that effectively blocks heat transfer [6]. Group 2: Space Efficiency and Cost-Effectiveness - A new composite wall made of soundproof gypsum board is significantly thinner (12 cm) compared to traditional brick walls (over 25 cm), while offering higher strength, fire resistance, and lower costs [8]. - The soundproof performance of the new wall reaches an impressive 66 decibels, effectively blocking out sounds such as piano playing from adjacent rooms [8]. - The reduction in wall thickness allows for an increase in indoor space, potentially adding around 8 square meters to a typical 100 square meter apartment, equivalent to an additional small room [9].
