Granulated blast furnace slag powder on the influence of concrete CGM high-strength non-shrinkage grouting material have? - Guangxi grouting material manufacturers

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer granulated blast furnace slag, drying, grinding, Or add a few gypsum powder grinding together) To achieve proper powder fineness and agree with the corresponding activity index, called the granulated blast furnace slag powder, referred to as 'slag powder, also called GGBS, is carried out in recent years of grouting material price sg560 to a highly functional mineral admixture. 1, granulated blast furnace slag powder skill building materials suggest adding slag powder in concrete CGM high-strength non-shrinkage grouting material should fit the quality of the used in cement and concrete grouting guess the graining of blast furnace slag powder, the rules of specification. 2, granulating, blast furnace slag powder on the influence of concrete CGM high-strength non-shrinkage grouting material function graining blast furnace slag powder on fresh concrete effect of CGM high-strength non-shrinkage grouting material function; Concrete grouting material unit water consumption with slag powder increased with the decrease of the specific surface area, along with the augment of displacement rate cuts. Slag powder on concrete grouting material secrete water and bleeding rate of sichuan ring first depends on the fineness of slag powder. When slag powder than that of cement, and replace the same volume group, secrete water cut; On the contrary, when slag powder coarser, secrete water and exudation rate may be added. The smaller the specific surface area of the slag powder, the replacement rate, the greater the mixing slag powder concrete grouting material of condensing the longer time. 3, graining blast furnace slag powder of hardened concrete CGM high-strength non-shrinkage grouting material function before and after the impact of the slag powder of benchmark CGM high-strength non-shrinkage grouting material, concrete mixing slag powder, the early strength of concrete grouting material before 7 d fell. Slag powder manufacturers than huanggang grouting material surface area is smaller, the greater the replacement rate of cement; Maintenance of temperature is lower, the early strength increase slower, but the later strength increasing rate is higher, especially good for flexural strength of concrete grouting material progress. Slag powder can optimize the structure of concrete grouting material field, advances the impermeability of concrete grouting material function, decline in the chloride ion diffusion speed, cutting system, the content of calcium hydroxide in bay JianJiLiao reaction, advances the concrete grouting material resistance to sulfate corrosion ability, improve obviously the durability of concrete grouting material function. 4, graining blast furnace slag powder in concrete CGM high-strength non-shrinkage grouting material used in building materials manufacturing concrete prompt CGM high-strength non-shrinkage grouting material, slag powder to replace cement quality such as usually.
