The influence factors of cement grouting material application specification - Guiyang grouting material manufacturers

Cement grouting material CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material influence factors of cement grouting material used in the specification design of CGM high-strength non-shrinkage grouting material with high strength material as aggregate, cement as the seam an agent, complementary with high flow, micro expansion, segregation, etc. It in the construction site shall be quantitative water, stir well after use. CGM high-strength non-shrinkage grouting material has good artesian, rapid hardening, early strength, high strength, no shrinkage, micro expansion; Nontoxic and harmless, not aging, on the water quality and the surrounding environment pollution-free, good tightness, rust etc. In construction has reliable quality, reduce cost, shorten the construction period and application is convenient wait for strengths. Fundamentally change the stress state of equipment base, and make it evenly carry the full load of the equipment, and meet all kinds of machinery, electrical equipment, Heavy equipment and high precision grinding machine) Device requirements, is the ideal of the pad device times grouting material. The influence factors are as follows: 1. Folding cooperation than: after reasonable cooperation than planning, make the CGM high-strength non-shrinkage grouting material intensity is higher; CGM high-strength non-shrinkage grouting material and how much water ratio 2. Folding water-cement ratio: CGM high-strength non-shrinkage grouting material compressive strength and CGM high-strength non-shrinkage grouting material is proportional with the strength of the cement, according to the formula calculation, when the same water-cement ratio, high strength grade of cement is larger than that of low strength grade of cement produce CGM high-strength non-shrinkage grouting material high compressive strength. Other, water cement ratio is proportional to the intensity of CGM high-strength non-shrinkage grouting material, therefore, when the water cement ratio is constant, in an attempt to improve the strength of concrete by adding cement dosage is wrong, at the moment can only increase the CGM high-strength non-shrinkage grouting material workability, increasing the CGM high-strength non-shrinkage grouting material shrinkage and deformation. Wuhan CGM high-strength non-shrinkage grouting material 1 ton anyway, how much influence the CGM high-strength non-shrinkage grouting material is the first element of the compressive strength of cement strength and water cement ratio, to control the CGM high-strength non-shrinkage grouting material quality, more important is to control the cement and CGM high-strength non-shrinkage grouting material water cement ratio of the two primary part. In addition, the influence of CGM high-strength non-shrinkage grouting material intensity and other factors can not be ignored. 3. Folding aggregate, aggregate strength of CGM high-strength non-shrinkage grouting material has bound to influence, when the rock strength is equal, coarse gravel appearance than pebble appearance, its better than pebble bonding with cement mortar, as the water cement ratio is equal or cooperation than photograph together, two kinds of materials made in CGM high-strength non-shrinkage grouting material, gravel CGM high-strength non-shrinkage grouting material strength is better than the pebble. Varieties of fine aggregate strength of CGM high-strength non-shrinkage grouting material is smaller than the aggregate impact degree, so the CGM high-strength non-shrinkage grouting material in the formula does not reflect sand and soft effect, but the quality of the sand quality of CGM high-strength non-shrinkage grouting material has must of influence. Thus, sand quality must conform to the mortar CGM high-strength non-shrinkage grouting material used the label of CGM high-strength non-shrinkage grouting material sand quality standard requirements. Due to the construction site sand quality change is opposite bigger, and on-site construction personnel must guarantee the quality of sand and gravel requirement, and according to the on-site adjust water cement ratio, sand moisture content to ensure the CGM high-strength non-shrinkage grouting material cooperation than, cannot confuse trial proportioning ratio and construction; 4. Folding compactness: at the scene of the casting is bound to the CGM high-strength non-shrinkage grouting material vibrating evenly, discharge the air inside, add the CGM high-strength non-shrinkage grouting material density; 5. Fold the late maintenance: the late should be maintenance according to the rules of the construction standards, the temperature of concave and convex strength of CGM high-strength non-shrinkage grouting material for a must. Winter insulation against the cold, the summer to prevent exposure, dehydration. Now the winter construction generally adopt induction heat and steam curing.
