Grouting material model of the influence factors of grouting material - Guiyang grouting material manufacturers

grouting material type grouting material manufacturer CGM high-strength non-shrinkage grouting material manufacturers, main factors affecting grouting material filling material with high strength material as aggregate, cement as the seam an agent, complementary with high flow, micro expansion, segregation, etc. In the construction site for a certain amount of water, use after mixing evenly. Grouting material has good artesian, rapid hardening, early strength, high strength, no shorter, micro expansion; Non-toxic, harmless, not aging, on the water quality and the surrounding environment pollution-free, since the tightness good, rust etc. Characteristics. 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, accept all equipment load evenly, so satisfied with 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: through reasonable cooperation than design, higher strength of grouting material; How much 2 grouting material ratio with water. Folding water cement ratio, grouting material compressive strength is proportional to the strength of grouting material with cement, according to the formula calculation, when the water cement ratio is flat, high strength grade of cement than low strength grade of cement grouting materials were produced in the high compressive strength. In addition, water cement ratio is proportional to the strength of grouting material, therefore, when the water cement ratio is constant, on the run from the progress of concrete strength by adding cement dosage is fault, at the moment can only increase grouting material workability, increasing grouting material and the decreasing of the deformation. Wuhan grouting material 1 ton how much money it, primary factors affecting the compressive strength of grouting material is cement strength and water cement ratio, to control the quality of grouting material, more important is to control the good water cement ratio of the concrete and grouting two primary part. In addition, the impact strength of grouting material and other factors can't ignore. 3. Folding aggregate, aggregate strength of grouting material also has certain influence, when flat rock strength, coarse gravel appearance than pebble appearance, its better than pebble bonding with cement mortar, as the water cement ratio than flat or cooperation together, and two kinds of materials made of grouting materials, grouting material strength are better than pebbles. 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 sand quality of grouting material has a certain influence. Thus, sand quality must fit into mortar grouting grouting material each label with sand quality standard requirements. Because a relatively large changes in the construction site sand quality, thus the construction personnel must ensure the quality of sand and gravel, and sand moisture content based on site in a timely manner to adjust water cement ratio, to ensure that the grouting material cooperation than, can't equate the trial proportioning ratio and construction; 4. Folding compactness: at the scene of the casting must grouting material vibrating evenly, discharge the air inside, add the density of grouting material; 5. Fold the late maintenance: the late should be maintenance according to the norms of construction, high and low temperature strength of grouting material has a certain impact. Winter insulation against the cold, the summer to prevent exposure, dehydration. Now the winter construction generally adopt induction heat and steam curing.
