    1. **: The anti-cracking agent is nearly twice as high as the anti-cracking fiber.

    2. Scope of use: anti-cracking agents are widely used in civil buildings, bridges, highways, airstrips, and dams, while anti-cracking fibers are mainly used for steel wire mesh polystyrene boards in external wall insulation systems.

    The surface is plastered with anti-crack requirements. Anti-crack fiber is a kind of anti-crack fiber that is made of 100% polypropylene as raw material, through a unique process and equipment, through melting, extrusion, drawing, cutting and other processes.

    In order to ensure that the anti-crack fibers can be well dispersed in mortar, cement concrete, the anti-crack fibers are also subjected to a special process for surface treatment before cutting.

    Because it mainly uses polypropylene as a raw material, it is also known as polypropylene fiber.

    The anti-crack fibers act on mortar and cement cement in water, relying on their unique tensile strength.

    Dispersion, melting ignition point, acid and alkali resistance and other properties can effectively prevent the formation and development of maintenance cracks in mortar and cement concrete. The anti-cracking agent is an organic polymer mixed emulsion that makes full use of cement mortar.

    and the mechanism of physical and chemical imitation changes in the curing process of concrete, and the powder synthesized by Dabigong can be used to prevent and resist cracking from both physical and chemical aspects, which can significantly improve the strength of cement mortar and concrete. Anti-cracking agent can effectively solve the problems of surface plastering difficulties and easy cracking caused by the smooth surface of polystyrene board and non-water absorption, and the addition of anti-cracking agent to cement mortar and concrete can greatly reduce the cracks and hollowing of mortar and concrete.

    The generation of phenomena increases the strength of the mortar and improves the quality of the project. The anti-cracking agent solves the problems of large dry shrinkage deformation, impermeability, crack resistance and poor frost resistance of ordinary cement mortar, and can effectively control the plastic shrinkage and cracks caused by segregation of mortar concrete directly incorporated into cement, and greatly improve the crack resistance, frost and impact resistance and wear and seismic resistance of mortar concrete.

    Pro, this question is answered by me, oh pro, pro, anti-crack fiber is an admixture of concrete, oh dear, pro, the following is the effect of adding anti-cracking fiber to concrete, oh pro 1Fibers are added to concrete, and from the time the concrete is poured until it hardens, the concrete has not yet developed enough strength to resist the cracks caused by cement shrinkage2After being incorporated into the fiber, it can counteract part of the internal coincidence stress to inhibit the generation and propagation of microcracks.

    The fibers in the concrete are distributed in a three-dimensional manner, some are in places where there are no cracks, and some are across the microcracks that exist in the concrete. 3.For the fibers bridging between cracks, they can play a crack blocking role after the initial crack of concrete, similar to the role of steel bars, bear the effect of interfacial transmission, and inhibit the further propagation <> cracks

    Fiber Reinforced Concrete: A general term for a composite material composed of a fiber and a cement base (cement stone, mortar or concrete). The main disadvantages of cement, mortar and concrete are:

    Low tensile strength, small ultimate elongation, brittleness, the addition of high tensile strength, high ultimate elongation, good alkali resistance fiber, can overcome these shortcomings.

    The fibers used can be divided into metal fibers according to their material properties: Metallic fibers. Such as steel fiber (steel fiber reinforced concrete), stainless steel fiber (suitable for heat-resistant concrete).

    Inorganic fibers. There are mainly natural mineral fibers (chrysotile castos, crocidolite, amosite, etc.) and man-made mineral fibers (alkali-resistant glass fibers and alkali-resistant mineral wool and other carbon fibers). Organic fibers.

    There are mainly synthetic fibers (polyethylene, polypropylene, polyvinyl alcohol, nylon, aromatic polyimide, etc.) and plant fibers (cisarma, agave, etc.), synthetic fiber reinforced concrete should not be used in a thermal environment higher than 60.

    Compared with ordinary concrete, fiber reinforced concrete has many advantages, but after all, it cannot replace reinforced concrete. People began to add fibers to reinforced concrete to make it rebar-fiber composite concrete, which in turn developed a new way for the application of fiber reinforced concrete.
