Core Viewpoint - During the "14th Five-Year Plan" period, China's building materials industry has made significant advancements in technological innovation, with the China Building Materials Federation announcing seven breakthrough technological achievements for the industry by 2025 [1][2]. Group 1: Technological Innovations - The seven newly announced products and technologies include a "super intelligent" unmanned cement factory, ultra-pure silicon carbide made with lasers, super light-blocking glass, a digital platform for R&D, "super cool cement" that does not heat up, high-temperature resistant silicon-based aerogels, and next-generation display glass with large widths [2][4]. - The global first "unmanned cement production line" has been introduced, which automates the production process, significantly reducing the need for human labor compared to traditional cement production lines [5][7]. Group 2: Investment and R&D - The intensity of R&D investment in the building materials industry is projected to reach 1.32% by 2024, an increase of 0.44 percentage points from 2020, reflecting a stronger focus on technological innovation [4]. - The industry has established a "challenge and reward" mechanism for major technological breakthroughs, accelerating advancements in key areas such as green and low-carbon technologies, artificial intelligence, and super materials [4]. Group 3: Product Features and Applications - The "super cool cement" is notable for its ability to self-cool without electricity, demonstrating significant temperature reduction capabilities and strong fire resistance and compressive strength [14][19]. - The material has a solar reflectance rate of 96.2% and a thermal radiation rate of 96%, allowing it to effectively mitigate urban heat island effects and reduce building energy consumption, making it suitable for applications in roofing, exterior walls, urban pavements, and cold chain storage [19].
