Four kinds of filling form structural fracture repair

In the concrete structure crack and craze phenomenon are inevitable. Structure cracks may occur, both in the initial stage and on time. Can use various material sealing cracks; One of them is the grouting. Grouting material is sticky, Thick and sticky liquid, is not easy to flow) , can fill material can be used to fill the space between two components to glue them or form a waterproof seal. Grouting is usually used to fill the gap of cement, sand and water mixture. They are used in repairing concrete crack, fill in the ceramic tile juncture and aperture, sealing and filling gaps in waterproof, and used for soil stabilization. It is also used to provide the basis of the bearing structure of extra strength. Here, we try to before fracture work, provide some home owners should know the basic information of the grouting and its type. Grouting is used in various applications, such as repair cracks, drains, water tunnel and other underwater structures, fill the seam between the ceramic tile, and the stability of soil. Here, we briefly introduces the grouting used in the crack repair type. Building and repairing project of grouting is divided into the following categories: 01. Cement grouting, cement grout is also known as slurry grouting or hydraulic cement grouting. Slurry used for sealing wide crack, especially in the gravity dam, channel lining, ground and thick concrete walls, and is also used to enhance the machine or equipment such as machine foundation, or the additional strength of anchor bolt. According to the size of the particles, it is divided into the following categories: ordinary Portland cement: this is the most common types used in repairing concrete crack of cement slurry. Using OPC grouting can populate the wider fracture, because their particle size of 15 microns. Microfine cement: it is a fine grinding slag, or Portland cement, fine fly ash are mixed with water, can infiltrate the tiny cracks. Silicon dioxide sinks or any other fine ash can be used together with the micro fiber. Fine slurry particle size in the range of 6 to 10 microns. The superfine cement grouting: they are used in sealing very fine hairline cracks. They have 3 to 5 micron particles.

Chemical grouting: chemical pulp is composed of polymers, such as acrylic, polyurethane, sodium silicate, epoxy resin or any other suitable polymer. Chemical pulp is water and liquid resin emulsion. Chemical grouting to special formula of chemical grouting into fine cracks, is this slurry cannot be achieved. They can be used in damp environment, and can fill the very small cracks. With bending and tensile properties of acrylic coating. It allows less water infiltration. Acrylate grouting for sealing wall cracks. Epoxy grouting is a kind of excellent materials, applied to require high strength grouting application. Epoxy grouting is not shrinking, sticky, and are highly effective in sealing cracks. Them with almost all construction material has good adhesiveness, and good chemical resistance 03. Polyester base grouting: polyester used for grouting anchor to give must be in the basis of the strength within the limited space available. According to the requirements of end users can also by adding different additives to make it has special features, such as rapid solidification, free flow, no shrinkage, etc. 04. No shrinkage grouting: no shrinkage grouting can be used to seal is expected to shrink the cracks. The grouting is specially prepared with cement, aggregate and other special additives mixtures, to compensate for possible contraction, liquidity and clotting factors. The shrinkage grouting is used to connect to precast concrete parts. There are all kinds of grouting can be used to repair the cracks in concrete. For general purposes, the most commonly used is cement, for the industrial cracks, preferred chemical grouting. India's popular grouting manufacturer is:
