With the continuous improvement of the living standards of the rural people, every household has built a small second floor, a small villa. As a house of many self-built and small construction teams, cracks will occur when the time is not long. Then, can cracks in self-built houses be reinforced?
The answer is obviously ok. In fact, the question is how to carry out the reinforcement of the building and how to use it for reinforcement.
First, a crack check is required. Thoroughly check the nature of the crack and the length, width, depth, strike, penetration and water leakage of the crack to determine the treatment plan. The width of the crack can be measured with a reading microscope, and the depth and direction of the crack can be examined by means of ultrasound, pressurized water or drilling.
After the crack treatment is carried out on the cracks of the smaller concrete members, the tools such as wire brushes are used to remove dust, scum and loose layers on the surface of the concrete cracks, and the floating ash is brushed off, and wipe clean with 2~3cm on both sides of the seam with alcohol and fill the glue. Mankate filling glue can be injected into 0.1mm micro-cracks. It has excellent toughness and impact resistance after curing, and is non-toxic and harmless.
For deeper cracks in larger concrete members, a "V" shaped groove can be cut along the crack in order to effectively seal. For larger concrete members or deeper cracks, drilling can be applied along the cracks to allow the slurry to enter the cracks with a wider passage.
Then set the glue nozzle. In the staggered part s of the cracks, the wide cracks and the crack ends must be provided with a glue nozzle. The spacing of the glue nozzle depends on the size, direction and structure of the cracks. Generally, when the width of the slit is 0.3 to 0.5 mm, the distance between the nozzles is 20 to 30 cm. A slurry, vent or sump outlet must be placed on a crack.
The glue nozzle can be pasted with the crack repair glue at the predetermined position, or it can be pasted together at the time of sealing. Special care should be taken to prevent blockage of the nozzle.
The quality of the filling glue affects the effect and quality, and should be given special attention. Wet filling is recommended to use Mankate filling glue, which is a two-component material, containing A and B components, and the weight ratio is 3:1, the viscosity is low, the strength is higher than concrete, and the penetration is strong. Special glue injection equipment should be used for the filling operation. Before the glue is applied, the compressed air is used to blow the pores to a dry state. According to the size of the crack area, single hole filling or group hole filling can be used. The glue on a crack can be from shallow to deep, from top to bottom, from one end to the other.
Mankate filling glue, the gel is transparent, without any impurities, non-toxic and tasteless, free on-site technical support. Insurance companies underwrite, China's famous products, can be trusted.
