Zhengzhou grouting materials, grouting materials - mechanical properties and structure analysis The performance of high strength grouting material

grouting zhengzhou grouting grouting material manufacturer grouting material hardening after necessary has certain mechanical properties can meet the engineering requirements, these properties include; Compressive strength, splitting tensile strength, flexural strength, elastic modulus, poisson's ratio, the triaxial stress, creep strength, abrasion resistance, grouting material and the cohesive strength between steel and permeability resistance, etc. FuWuHan grouting LiaoChang close data point of view should be used to evaluate the mechanical properties of grouting material, the so-called composite materials refers to two or more different chemical and mechanical properties of materials together constitute a three-dimensional complex, has a clear interface between the data. The influencing factors of grouting material mechanical properties; Particle shape, size and size distribution, were dispersed phase and the phase composition and distribution, interfacial transition zone properties and pore structure. General general grouting material refers to the structure of grouting material composed of cement, sand, stone and water mixing, the cement hydration hardening and become a kind of artificial stone, first used for acceptance of load structure data. In order to improve construction performance and mechanical properties of grouting materials, often join some beauty plus seam an agent and mineral admixture, the grouting time, sand, stone, a skeleton effect, known as the aggregate; Cement and water slurry, water slurry mixing content must have liquidity, convenient for construction. Become xian cement slurry condensation hardened steel structure of grouting materials, stone and aggregate bond into a solid overall. After grouting material hardening, before loading, the interior has the presence of large amounts of the original crack is invisible to the naked eye, which is given priority to with interface micro cracks. These micro cracks because of the volume changes of slurry in the hardening process with the coarse pedestal grouting material aggregate volume change. Other, because after grouting material molding exudation effect, make water gap at the bottom of the coarse aggregate, after waiting for grouting material hardening, water transpiration, made the interface micro cracks. These micro interface crack spread in coarse aggregate and hardened cement bonding surface, has enormous influence on the strength of grouting material.
