Shanghai - grouting material crack control Grouting material

grouting CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material factory 1, restricted shrinkage is more common grouting material cracking is the main reason. In practical engineering, the deformation of grouting material has reinforced, adjacent, foundation and structure of the whole; Free deformation is almost nonexistent. So, the control and the control of the restricted shrinkage cracks. 2, is an exact definition of shrinkage compensation grouting material: with grouting material limit expansion restricted shrinkage compensation grouting material. Shrinkage compensation grouting and ordinary grouting material is to use the trademark difference between expansion cement or the seam an agent, giving it a moderate inflation, generation of compressive stress, the expansion of the steel used for compensating shrinkage with the cold. 3, the grouting material cracks are not all bad, some of the cracks are allowed to happen. Cracks are harmful or harmful size depends on the function of the structure, environment, and crack their positions. Shrinkage compensation grouting material for a reduced harmful cracks, for the purpose of it is not necessary, it is impossible to guarantee to eliminate all the cracks. , end grouting material contraction deformation extension is not greater than the limit of the grouting material, grouting material won't craze. Grouting material can limit expansion part or most of the compensating contraction deformation, the stronger the compensation ability effect, the greater the more final shrinkage deformation is smaller, the more conducive to reduce or avoid the occurrence of cracks and development, the crack limit in the harmless grouting material supply scope. 5, shrinkage compensation grouting material belongs to the high performance concrete grouting material plants in chengdu, is likely to gradually replace ordinary grouting material. Shrinkage compensation technology is mainly used in the cracking and waterproof to demand higher engineering. Because the modern structures has long, large volume, the characteristics of erosion resistance requirements, need grouting materials, grouting material with a solid density, makes every effort to reduce the harmful cracks, shrinkage compensation grouting material in improving crack resistance of can obtain high density at the same time, therefore, for grouting material engineering, implementation of the technology is a reasonable, cheap prevention or insurance measures, this will determine his broad grouting material bottle expanding application range images.
