CGM grout reinforcement material model exudation is what reason - Type difference of grouting material and coating

grouting type grouting reinforcement material model CGM grouting reinforcement type grouting reinforcement material model is made up of different particle size and density of different kinds of solid and liquid composite material, in cement ( Or other gelling materials) Agglutination process, dense particle sedimentation, so the solid particles and water separation, namely new mix reinforcement grouting material model will inevitably occur secrete water surface, secrete more serious, water surface grouting reinforcement CGM grout material model of the construction plan of water cement ratio is larger. Factors of influencing strengthening grouting material type secrete water mainly include strengthening grouting material model collaboration ratio and composition of materials, construction and maintenance of tianjin epoxy resin grouting material type and so on. Grouting reinforcement models of collaboration than reinforcement grouting material models of water cement ratio, the greater the agglutinate hardening cement, the longer the more free water, water and cement, the longer separation grouting reinforcement material model more brief exudation; Grouting reinforcement guess plus the seam an agent dosage too much, or too retarded component content, would amount to a new mixed reinforcement grouting material models of many exudation and settling out, a lot of free water secrete the grouting reinforcement material type appearance, affect the agglutination of cement hardening, grouting reinforcement material type water function decline, causing severe bleeding. Grouting reinforcement material models of sand and gravel aggregate composition data containing mud is large, the serious influence the early hydration of cement, cement clay will package of clay particles, delay and resistance of cement hydration and grouting reinforcement types of agglutination and thus aggravate the grouting reinforcement material models of exudation; The greater the fineness modulus of sand, sand, the more thick, more easy to constitute the grouting reinforcement material model exudation, especially 0. 15 mm and 2 below. More than 5 mm particle content on the exudation of influence: the less fine particles, the more coarse particle, grouting reinforcement material model more Yi Bi water; Mineral admixture particles scattered also affects the same reinforcement grouting material types of bleeding, less if the fine particle content of mineral admixture, coarse particle content, is easy to form reinforced grouting material types of bleeding. With fine grinding slag admixture, for cooperation than in the dosage of cement, slag hydration speed slower, and slag vitreous water effect is poorer, tend to increase the grouting reinforcement material models of secrete water; Fly ash too coarse and fine aggregate effect is abate, also can increase grouting reinforcement material type secrete water cement chemistry. As cement grouting reinforcement guess more important gelled material, and the grouting reinforcement material models of exudation function are closely related. The coagulation time of cement, fineness, than appearance product with the spread of particles will affect the exudation functions of grouting reinforcement material model. The agglutination of cement, the longer the grouting reinforcement material made model aggregation, the longer and longer duration of agglutination net oar exponentially growing, ups and downs than the cement in grouting reinforcement material model let stand, agglutination before hardening cement particle sedimentation, the longer grouting reinforcement material model more Yi Bi water; Cement fineness and the coarser than the appearance of the product, the smaller the particles scattered in the fine particles ( < 5 ^米) Content is less, the early cement hydration quantity is less, less hydration products is not enough to block the wool stoma of grouting reinforcement guess, and under the internal moisture a brief since zhengzhou epoxy grouting material model manufacturer campaign, the grouting reinforcement material model secrete water the more serious. ”
