. Expansive fiber anti-crack waterproofing agent
. Implementation standard: "Mortar, Concrete Waterproofing Agent"
. Product Introduction
. In the process of hardening of concrete to form strength, the initial water content is It reacts with cement to form crystals. The volume of this crystalline compound is smaller than the volume of the raw materials, thus causing the volume of concrete to shrink. In the later stage, cracking factors such as shrinkage and temperature changes caused by the evaporation of free moisture in the concrete are the root causes of many problems in concrete.
. Since the monofilament fibers in the expanded fibers are evenly distributed inside the concrete in large numbers per unit volume, micro-cracks must be blocked by the fibers during their development, consuming most of the energy. << br/>-The four expansion components hydrate at different rates at the same time. During the formation process of concrete, they establish different micro-expansion forces in the early, middle and late stages, resisting Unload the shrinkage force of concrete at different stages during the formation process, so cracks are difficult to develop further, thereby blocking cracks and achieving anti-cracking effect. In particular, the addition of fibers is equivalent to adding a huge number of micro-rebars into concrete. These fiber bars inhibit the cracking process of concrete and improve the fracture toughness of concrete, which cannot be achieved by reinforcing steel bars alone.
