CGM pedestal grouting material - performance research Henan where to sell bearing grouting material

Bearing grouting support grouting material price new bearing pedestal grouting material price CGM grout material function discussion 1, CGM pedestal grouting material is a kind of early strength, high strength, high flow, micro swelling and good durability, and other advantages of new composite materials. To this end, it contains research and development of the flow pattern of concrete, high early strength of concrete, swell concrete and application of a variety of skills, plus the seam an agent with inorganic cementitious materials and high strength bone fuss pedestal grouting material is given priority to, through adding different kinds of plus the seam an agent makes the product has the function of all kinds of requirements. Chongqing pedestal grouting used in grouting equipment CGM pedestal grouting material information is one kind has high strength, high early strength, activity and micro swell features such as mixing material. It is mainly made of special cementing materials, swelling materials, high strength of aggregate and various and beautiful seam an agent. Now to introduce the experimental effect. Activity index is grouting construction without effective important condition. According to foreign design, general requirements pedestal grouting material jump table activity is greater than 240 mm, to ensure that support grouting materials based on weight or a little dao can flow into the need to fill all the space. According to different water ratio measurement of CGM pedestal grouting material and intensity of mobility, figure 1 in table 2 show CGM pedestal grouting material increase with the adding activity water use, and the compressive strength is reduced. In different temperature conditions according to the experiment, the data of activity time impact on activity are shown in table 3. Should pay attention to during construction mixing good bearing grouting material shoulds not be long. 2, condensation condensation moment moment pedestal grouting materials directly affect the continuity and quality of construction. CGM gelling material hydration speed changes according to the different environmental temperature, condensation moment changed also. By determination of different temperature, and the activity of CGM condensation moment. 3, limit swelling in equipment installation, use bearing grouting material casting secondary grouting layer height not less than the initial appearance luming height on the appearance, and to have surely swell up change, this deformation is called the vertical limit swelling. Anchor bolt anchorage is must the swelling stress of the anchor bolts in stress field, can greatly improve the ability of resistance to drawing. As shown in figure 2, table 5 shows that support grouting materials put how many water CGM pedestal grouting materials at room temperature are bound to the vertical limit swell, limit swelling rate at 0. 010% ~ 0. Within the scope of 040%, and about ten days to stabilize after grouting.
