High-performance Polypropylene Fiber Anti-cracking Concrete

In construction, concrete cracking has always been a thorny issue affecting the quality and lifespan of buildings. A concrete company in Shandong has successfully applied for a patent named "A High-performance Polypropylene Fiber Anti-cracking Concrete and Its Preparation Method". This achievement has drawn attention in the building materials field and provided an innovative solution to the cracking problem. Through an innovative formula, on the basis of traditional concrete raw materials, cement, aggregates, mineral admixtures, water reducers, and expansion agents are added in specific weight ratios, and modified polypropylene fibers and nano-silica with a mass ratio of (1.7 - 2.4):1 are incorporated as anti-cracking agents. The optimized preparation process ensures that the modified polypropylene fibers are evenly distributed in the concrete matrix, significantly enhancing the bond strength between the fibers and the concrete.

Tests have shown that this patented product has excellent anti-cracking and durability properties. Under the same conditions, compared with ordinary concrete, the probability of cracks occurring is significantly reduced, and the seismic performance is also significantly improved, effectively extending the service life of buildings and enhancing safety. With the popularization of green building concepts, this high-performance polypropylene fiber anti-cracking concrete is expected to shine in the future construction market and drive the industry towards a more environmentally friendly and durable direction.
