. Product introduction
. Fiber anti-crack expansion waterproofing agent is a new generation of domestic multi-functional waterproofing agent. It is scientifically compounded with redispersible polymers, multi-elastic expansion components and high-strength polypropylene fibers. This product has the functions of early strength, micro-expansion, compensation for shrinkage and improvement of concrete's resistance to cracking and seepage.
. Since the monofilament fibers in the fiber anti-crack expansion waterproofing agent are evenly distributed inside the concrete in a large number per unit volume, the micro-cracks are blocked by the fibers during the development process and consume most of the energy. The multiple expansion sources of the fiber anti-crack expansion waterproofing agent can establish different micro-expansion forces in the early, middle and late stages of the concrete formation process to offset the shrinkage of the concrete at different stages during the formation process, making it difficult for cracks to develop further. , to achieve the effect of anti-cracking.
. The existence of fibers is like adding a huge number of fine bars into concrete, forming a secondary reinforcement effect in the concrete, allowing the expansion components to fully exert themselves under restricted conditions, and the superimposed effect makes the concrete more Dense and stable, it improves the toughness of concrete and greatly reduces the cracking process, which cannot be achieved by reinforcing steel bars alone.
. Fibers are randomly distributed in concrete to form a three-dimensional network structure. The expansion component compensates for shrinkage, and the redispersible polymer plays a bonding and hydrophobic role. The superposition effect produced by the mutual complementation of the three is very Reduce cracks to the greatest extent, control the occurrence of harmful cracks, and give concrete new vitality.
. Fiber anti-crack expansion waterproofing agent can be used for seamless construction of ultra-long structures. The design specification stipulates that a post-pouring joint should be set every 3 meters, which will extend the construction period and make construction troublesome. This agent is used to replace the post-pouring joints with reinforced belts, which has good integrity and greatly shortens the construction period. It has been greatly recognized by the design and construction circles. , the engineering application effect is good. The specific method is: set up a 1-meter-wide reinforcing belt with the post-pouring joint as the center, and use steel wire mesh on both sides of the belt to prevent the concrete outside the belt from flowing into the belt. Appropriately add horizontal structural ribs within the belt. When pouring, add this agent to the concrete on both sides of the reinforced belt. The strength grade of the concrete in the belt should be increased by one level accordingly, and this agent can be added at the same time.
. Dosage
. Dense waterproof concrete should be based on the weight of the cementitious material
. Compensating shrinkage concrete should be based on the weight of the cementitious material
. Filling concrete should be based on the weight of the cementitious material -.
. How to use
. Pay attention to accurate weighing and extend the stirring time appropriately.
. The construction and curing process of concrete with fiber anti-crack expansion waterproofing agent is exactly the same as that of ordinary concrete, and the curing period is not less than.
. Packaging and storage
. .Outer braided inner plastic packaging. Net weight per bag
. .Moisture-proof storage. Shelf life of one year
