How do you ensure that high-strength non-shrink grout material has a good construction performance? - Anyang high-strength non-shrink grout material price

High-strength non-shrink grout high-strength non-shrink grout material price high-strength non-shrink grout material manufacturers in the process of civil engineering construction, in order to obtain dense and uniform concrete high-strength non-shrink grout material structure to facilitate construction operation ( Mixing, transportation, pouring and vibrating process) For fresh concrete high-strength non-shrink grout material has a good construction performance, such as keeping fresh high-strength non-shrink grout material side how many tons of concrete grouting material stratification and segregation does not occur, the phenomenon such as exudation, and obtain the uniform quality, forming dense concrete grouting material. This kind of fresh concrete, high strength non-shrinkage grouting material construction performance called the workability of fresh concrete grouting material. The difference between high-strength non-shrink grout material and castable. The workability of concrete grouting material mixture is one of the comprehensive technical performance, including liquidity, cohesion and the meaning of water retention three aspects. 1, the liquidity. Liquidity refers to the fresh concrete, high strength non-shrinkage grouting material under the action of gravity or mechanical vibration, the ability to flow with uniform and dense filling template. Liquidity directly affects the size of the vibrating construction difficulty and the quality of the hardened concrete grouting material, if the fresh concrete grouting material is too dry thick, is difficult to molding and tamping, and easy to cause internal and surface defects such as holes; If the fresh concrete grouting material too thin, easy appear after vibrating slurry and water buoyancy and larger particles such as stone aggregate sinking layered segregation phenomenon, affecting the uniformity of concrete grouting material quality, shaping the compactness. 2 and cohesion. Sticky cohesion refers to the fresh concrete high-strength non-shrink grout material between the composition of the material has a certain cohesion, make sure not happen stratification and segregation phenomenon, make concrete grouting material to maintain a uniform and stable performance. The poor cohesion of fresh concrete grouting material, easy to cause the stones and slurry separation, easy to appear the phenomenon such as honeycomb, holes after vibrating. 3, water retention. Fresh concrete high-strength non-shrink grout material's ability to maintain its internal moisture as water retention. Henan anyang high-strength non-shrink grout material suppliers to sum up, the liquidity of fresh concrete, high strength non-shrinkage grouting material, cohesion, and the correlation between water retention and restriction. Fresh concrete grouting material with good sex of cohesion, often water retention, but its liquidity may be relatively poor; Flow a lot of fresh concrete grouting material, often sticks on cohesion and poor water retention change trend. With the development of modern concrete grouting material, concrete high-strength non-shrink grout material pumping construction methods often used at present, the high requirement of the workability of fresh concrete grouting material, three aspects must be harmonious and unified performance to meet operation requirements, both late and to ensure good quality.
