Which influence the stability of CGM high-strength non-shrinkage grouting material volume factor - High strength grouting material standard specification

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer high function CGM high-strength non-shrinkage grouting material volume stability of liaoning dalian CGM high-strength non-shrinkage grouting material hit data, linear expansion, creep, and the decreasing of the construction, maintenance and other factors, and between these elements are contradictory to each other, restrict each other. Therefore, progress of CGM high-strength non-shrinkage grouting material volume stability, must choose from the original data, vibrating cooperation than planning to construction and maintenance methods. Gelling material: pay attention to consider when choosing gelling material hydration heat and the elements of water demand. Cement particles the thinner, the faster the cement hydration and gelling properties of cement useful utilization rate is higher. But using too fine prepared the cement fineness of CGM high-strength non-shrinkage grouting material, increased water consumption, and plus the adaptability of the seam an agent is poor, a new mixed CGM high-strength non-shrinkage grouting material slump lost faster, work function dongguan CGM high-strength non-shrinkage grouting material manufacturer. Cement C3A content is high in the early hydration heat is high, the thermal stress leads to increase in the number of micro cracks. Single or double mixing high quality fly ash and ground granulated slag not only could decrease the cement consumption, water consumption reduction, hydration heat, and can be cut in the early period of the CGM high-strength non-shrinkage grouting material shorten and cracking and improve the CGM high-strength non-shrinkage grouting material microstructure. Plus seam an agent in the United States: high efficiency water reducing the seam an agent is the function of CGM high-strength non-shrinkage grouting material (guess indispensable, but many highly effective water reducing the seam an agent of CGM high-strength non-shrinkage grouting material volume stability is bad, especially increased in the early period of the CGM high-strength non-shrinkage grouting material. Therefore, in the satisfaction with the seam an agent, on the basis of compatibility with cement, should choose smaller high efficiency water reducing effect on shortening the seam an agent. In aggregate, aggregate guess a larger share of the volume, the grouting guess the skeleton effect, and make the CGM high-strength non-shrinkage grouting material has better volume stability. Shanxi datong CGM high-strength non-shrinkage grouting material manufacturer in the aggregate volume content, elastic modulus, linear expansion coefficient, sand ratio and aggregate gradation, grain shape elements such as impact on the stability of CGM high-strength non-shrinkage grouting material volume is bigger. Fiber: in the grouting guess incorporating fiber volume stability is CGM high-strength non-shrinkage grouting material progress and useful way to avoid cracking. Low dosage of synthetic fiber not only will not affect the mixing mixing process of CGM high-strength non-shrinkage grouting material, and can significantly cut down the drying shrinkage of CGM high-strength non-shrinkage grouting material, and cut the CGM high-strength non-shrinkage grouting material from the cold. Cooperation than planning: volume stability in planning, cut CGM high-strength non-shrinkage grouting material should be shorten coefficient and linear expansion coefficient and elastic modulus, decline in CGM high-strength non-shrinkage grouting material stress slack factor. In order to reduce cracks of should, according to the way of CGM high-strength non-shrinkage grouting material structure and the environment, the influence of the CGM high-strength non-shrinkage grouting material cooperation than optimization, considering shortening rate to tensile strength, coefficient of linear expansion coefficient and elastic modulus and stress lax, progress as far as possible the ratio of tensile strength and modulus of elasticity, improve CGM high-strength non-shrinkage grouting material volume stability.
