Cold-rolled threaded steel bars can save approximately 20 steel bars, offering a more efficient and cost-effective solution in construction projects.
Overcast. Cement Modifier: The absurd cement modifier developed by the Suzhou Concrete Cement Product Research Institute is a highly efficient, multifunctional organic polymer emulsion. It is non-toxic, odorless, and appears as a milky white to yellowish liquid. When used in mortar, it significantly improves compaction, leading to over three times higher impermeability, more than 90% less water absorption, seven times better resistance to chloride ion penetration, and 23 times improved wear resistance. It also enhances bond strength with old concrete by up to five times, increases flexural strength, and greatly improves ultimate elongation and crack resistance. Its excellent aging resistance makes it an ideal material for structural repair and reinforcement, reducing labor such as manual cutting of vertical molds.
With the rise of fair-faced concrete construction, the demand for high-quality formwork materials has increased. These materials must offer high static bending strength, low elastic modulus, tight thickness tolerance, and excellent water and weather resistance, along with a smooth, wear-resistant surface. In response, the Guangdong Forestry Training Center developed face-strengthened plywood formwork using impregnated water-soluble phenolic resin glue-treated poplar veneer as the outer layer and masson pine veneer as the inner layer. Compared to traditional phenolic resin plywood templates, this new formwork offers superior static flexural strength, improved surface properties, especially enhanced wear resistance and flatness. All performance metrics exceed industry standards, making it ideal for clean concrete construction.
Toxic and harmful paints are being phased out. The China Coatings Industry Association recommended to the State Economic and Trade Commission to eliminate low-grade, toxic paints, including 107 coatings and modified starch-based coatings. These products are unsuitable for interior and exterior use due to poor water resistance and contain harmful formaldehyde. Today, synthetic resin emulsion-based latex paints, such as vinegar-acrylic and styrene-acrylic types, dominate the market and have completely replaced 107 paints. Buildings like the Kunlun Hotel in Beijing, which used vinegar-acrylic latex paint on their exterior walls since the 1980s, have remained in excellent condition, proving that domestic latex paints are both durable and suitable for long-term exterior use, ensuring a decorative lifespan of over 8–10 years.
Wuhan has successfully developed a multi-functional reflective heat-insulating and waterproof coating. The water-based coating, developed by the Wuhan Modern Industrial Technology Research Institute, has passed national tests and achieved technical performance comparable to foreign counterparts. Unlike traditional waterproof coatings, this product does not contain harmful solvents, is environmentally friendly, cures quickly, and offers excellent elasticity and aging resistance. It adheres well to various surfaces, even in humid conditions, and can be used directly as a waterproof layer without needing additional fiberglass cloth. It is available in multiple colors and can be mixed with cement mortar to prevent cracks and reduce leakage issues.
A non-fading decorative paint has been developed. The colored glaze quartz paint created by the National 863 High-tech Group at the university is a never-fading, glaze-like quartz sand-based decorative paint. It offers exceptional weather resistance, lasting decades, far exceeding the durability of conventional exterior coatings. It also features high stain resistance, excellent flame retardancy, and comes in 50 basic shades. Its low production and usage costs make it convenient for application through wiping or spraying. With 23 skilled workers, it’s possible to spray over 500 square meters per day, making it ideal for building surface decoration.
The inorganic adhesive produced by Shanghai Caoyang Construction Adhesive Factory is a construction adhesive that replaces traditional cement paste with thin-layer bonding. It includes a range of drilling agents such as tile adhesive 1300, brick inserting agent 1360, and concrete interface treatment agent 7400. Recently, new products have been introduced, such as the 1600 treatment agent, cement floor treatment agent 660, light wall masonry adhesive 1200, and waterproof adhesive 500, all designed to address common construction issues like hollow walls and cracks. These innovations provide advanced technologies to the construction industry.
