Cold-rolled threaded steel bars can save approximately 20 steel bars.
Overcast. Cement Modifier: The absurd cement modifier developed by the Suzhou Concrete Cement Product Research Institute is a highly efficient and multifunctional organic polymer emulsion. It is non-toxic, odorless, and has a milky white to yellowish liquid appearance. When used in mortar, it significantly improves compaction, resulting in more than three times higher impermeability, over 90% less water absorption, and more than seven times greater resistance to chloride ion penetration. Additionally, it enhances wear resistance by 23 times and increases bond strength with old concrete by up to five times. It also improves flexural strength, elongation, crack resistance, and aging resistance, making it an excellent material for structural repairs. This product helps reduce labor hours, such as manual cutting of vertical molds.
With the growing demand for fair-faced concrete construction, the requirements for formwork materials have become increasingly stringent. They must offer high static bending strength, low elastic modulus, precise thickness tolerance, and excellent water and weather resistance, along with a smooth, wear-resistant surface that is lightweight, easy to assemble and disassemble, and simple to demold. To meet these needs, the Guangdong Forestry Training Center developed face-strengthened plywood formwork using impregnated water-soluble phenolic resin glue on poplar veneer as the outer layer and masson pine veneer as the inner layer. Compared to traditional phenolic resin plywood templates, this new type offers improved static flexural strength, elastic modulus, and surface properties—especially enhanced wear resistance and flatness. All performance indicators exceed industry standards, meeting the strict requirements of clean concrete formwork.
Toxic and harmful paints are being phased out. The China Coatings Industry Association recommended to the State Economic and Trade Commission that toxic, low-grade paints, including 107 coatings and modified starch-based coatings, be eliminated. The main reason for this is that 107 paint lacks water resistance and is unsuitable for interior and exterior wall applications. It also contains formaldehyde, which is harmful to human health. Today, synthetic resin emulsion-based latex paints, such as vinegar-acrylic and styrene-acrylic types, dominate the domestic architectural paint market and have completely replaced 107 paints. In the 1980s, buildings like the Kunlun Hotel in Beijing used vinegar-acrylic latex paint on their exteriors, and they remain in good condition today. This proves that domestic latex paints are feasible and durable for exterior wall decoration, with a protective life of over 8–10 years, as confirmed by building reports.
Wuhan has successfully developed a multi-functional reflective heat-insulating and waterproof coating. The water-based reflective heat-insulating and waterproof coating developed by Wuhan Modern Industrial Technology Research Institute has passed national testing and achieved technical performance comparable to similar foreign products. This coating overcomes the environmental pollution and health risks associated with traditional solvent-based waterproof coatings. It meets eco-friendly standards, offers fast curing, excellent aging resistance, and strong adaptability to various substrates. It performs well even in humid environments without affecting the film quality. It can serve as a waterproof layer without requiring additional fiberglass cloth and can be customized into multiple colors. It can also be mixed with cement mortar to address cracking and leakage issues.
A non-fading decorative paint has been developed. The colored glaze quartz paint created by the National 863 High-tech Group at a university is a never-fading, glaze-like quartz sand decorative paint. It boasts long-lasting weather resistance, far exceeding that of regular exterior wall coatings. It also offers high stain resistance, color retention, and excellent flame retardancy, available in 50 basic shades. Its production and usage costs are low, and it’s easy to apply through wiping or spraying. Skilled workers can spray 50 or more pieces per day, making it ideal for decorating various types of buildings.
The inorganic adhesive produced by Shanghai Caoyang Construction Adhesive Factory is a construction adhesive that uses thin-layer bonding instead of traditional cement paste. 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 to address common issues like hollow walls, cracks, and poor adhesion. Examples include the cement floor treatment agent 660, light wall masonry adhesive 1200, and waterproof adhesive 500. These innovations provide advanced solutions for the construction industry.
