Grouting material strength is not enough because of what? - Shandong grouting material manufacturers

grouting CGM high-strength non-shrinkage grouting material strength of grouting material manufacturer determinants of the strength of the grouting material is first collaboration, water-cement ratio, aggregate, tianshui epoxy resin grouting material and the outside seam an agent, compactness and the maintenance of late. Collaboration than than collaboration with reasonable planning, make the strength of the grouting material is higher. Water cement ratio of grouting material and grouting material with compressive strength is directly proportional to the strength of the cement, according to the formula calculation, when the same water-cement ratio, often high strength grade of cement than low strength grade cement grouting material to produce high compressive strength. Other, water cement ratio is proportional to the strength of grouting material, therefore, when the water cement ratio is constant, by increasing the cement dosage to progress of concrete strength is wrong, at the moment can only increase grouting material workability, increasing grouting material and the decreasing of the deformation. In conclusion, the primary factors affecting the compressive strength of grouting material is cement strength and water cement ratio, to control good quality of grouting material, more important is a good cement grouting material and control the water cement ratio two primary part. In addition, the impact strength of grouting material zhengzhou grouting material factory factory prices and other factors can't ignore. Aggregate aggregate has bound to influence the strength of grouting material, when stone strength equal to often, gravel surface rough surface than a pebble, its better than pebble bonding with cement mortar, as the water cement ratio is equal or collaboration than photograph together, two kinds of materials of grouting materials, high strength grouting material manufacturer zhejiang rubble grouting material strength is better than the pebble. Varieties of fine aggregate strength of grouting material is smaller than the aggregate impact degree, so the formula of grouting material in sand do not reflect a soft effect, but the quality of the sand has surely affect the quality of grouting material. Thus, sand quality is necessary to conform to the grouting material each label with sand quality standard requirements. Because the sand quality changes to the construction site is opposite bigger, and on-site construction personnel necessary to guarantee the quality of sand and gravel, and according to the site adjust water cement ratio, sand moisture content to ensure that the grouting material cooperation than, can't equate the ratio of test proportioning and construction. Compactness of grouting material in casting field must be uniform vibrating, discharge the air inside, increase the density of grouting material. The late maintenance should be maintenance according to the rules of the construction standards, the temperature of concave and convex have must influence the development strength of grouting material. To prevent exposure to insulation against the cold in winter, summer dehydration. Now the winter construction general induction heat storage method and steam curing.
