CGM high-strength grouting material exudation

CGM high-strength grouting CGM high-strength grouting material manufacturer CGM high-strength grouting material price CGM high-strength grouting material is made up of different particle size and density of different composite material consisting of a variety of solid and liquid, the cement ( Or other gelling materials) The condensation process, the density of particles sedimentation, and the separation of the solid particles and water, namely the new mix of CGM high-strength grouting material will inevitably occur secrete water surface, secrete water more severe, the surface the greater the water cement ratio of CGM high-strength grouting material. Major factors that affect the CGM high-strength grouting material exudation with CGM high-strength grouting material cooperation ratio, composition of materials, construction and maintenance and so on. CGM high-strength grouting material cooperation than CGM high-strength grouting material of water cement ratio, the greater the condensation of cement hardening time longer, the more free water, water and cement, the longer the separation time CGM high-strength grouting material more easy bleeding; Grouting reinforcement guess plus the seam an agent dosage too much, or too retarded component content, will form a new mix CGM high-strength cgm1 grouting material model of grouting material many exudation and settling out, a lot of free water secrete the CGM high-strength grouting material appearance, influence of cement hardening, CGM high-strength grouting material function of water drops, causing severe bleeding. CGM high-strength grouting material composition of the material and gravel aggregate are too many mud, the serious influence the early hydration of cement, cement clay will package of clay particles, delay and resistance of cement hydration and CGM high-strength grouting material, thereby aggravating the exudation of CGM high-strength grouting material; The greater the fineness modulus of sand, sand, the more thick, more easy to form the CGM high-strength grouting material 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, CGM high-strength grouting material more Yi Bi water; Particle distribution of the mineral admixtures are also affects the exudation of CGM high-strength grouting material can work grouting material expiration, if mineral admixture of fine particle content is less, the coarse particle content more, is easy to form the exudation CGM high-strength grouting material. With fine grinding slag admixture, for cooperation than the dosage of cement, slag hydration speed slower, and slag vitreous water function is poorer, tend to increase the secretion of CGM high-strength grouting material of water; Fly ash too coarse and fine aggregate effect is abate, also can increase CGM high-strength grouting material secrete water cement chemistry. As cement grouting reinforcement guess more important gelled material, exudation and CGM high-strength grouting materials function are closely related. The coagulation time, fineness of cement, than the product appearance and particle size distribution will affect the CGM high-strength grouting material secrete water function. Of cement, the longer the time CGM high-strength grouting material was prepared by condensing the longer the time, and the extension of condensed moment magnitude than cement net oar exponentially growing, CGM high-strength prestressed grouting material prices before grouting material let stand, condense sclerosis, the longer the cement particle settling time, CGM high-strength grouting material more Yi Bi water; Cement fineness and the coarser than the appearance of the product, the smaller the particle size distribution of 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, the simple internal moisture movement from bottom to top, CGM high-strength grouting material exudation, the more serious. ”
