国内首次实现将混凝土泵送340米高空

Group 1 - The core achievement of China State Construction Material Concrete Co., Ltd. (CSMCC) is the development of LC35 all-light aggregate concrete, which has achieved a record pump height of 340 meters for super high-rise buildings in the Wuhan Yangtze Center project [1] - Traditionally, structures over 100 meters in height relied on steel structures for floor support to reduce weight; the introduction of all-light concrete provides a new solution for high-rise construction [1] - All-light concrete offers excellent sound insulation and thermal insulation properties, addressing common issues in high-rise residential buildings such as poor soundproofing and temperature regulation [1] Group 2 - The internal structure of all-light concrete is filled with closed micropores, which create an efficient thermal barrier for self-insulation; its porous structure and complex interfaces can absorb and scatter sound energy, effectively reducing noise [1] - The application of all-light concrete in building floors enhances the comfort of office and residential environments, representing a value upgrade from "good materials" to "good houses" [1]
