Building technology co. , LTD of CGM high-strength non-shrinkage grouting material quality control of raw materials

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer to the quality of the raw materials of zhengzhou high-strength non-shrinkage CGM high-strength non-shrinkage grouting material and its fluctuation, CGM high-strength non-shrinkage grouting material of concrete has a great impact on the quality and construction craft, in order to guarantee the quality of concrete CGM high-strength non-shrinkage grouting material, in the process of production, be sure to CGM high-strength non-shrinkage grouting material of concrete quality inspection of the raw materials, behind all conform to the technical performance indicators can be used. Harmful substance content in aggregate exceed the scope of the specification will hinder cement hydration, reduce the strength of the concrete CGM high-strength non-shrinkage grouting material, weaken the cohesive force of aggregate and cement, and cement hydration products for chemical reaction, and the expansion of the harmful substances. If the content of clay, silt sand in more than 3%, more than 2% in the gravel and pebbles, is the fine granular material was formed in the aggregate surface CGM high-strength non-shrinkage grouting material inspection according to the parcel layer, hinder the adhesive of the aggregate and cement, mixing also increased the content of water. Concrete CGM high-strength non-shrinkage grouting material moisture content and silt content and gravel aggregate powder content will CGM high-strength non-shrinkage grouting material mixing ratio of concrete, concrete CGM high-strength non-shrinkage grouting material strength is the main reason for the excessive volatility. CGM high-strength non-shrinkage grouting material in concrete production process, to the quality control of raw materials, in addition to the regular testing, also requires a quality control personnel can know the change rule of its content, and proposed the corresponding countermeasures. Adjust according to the determination of the moisture content of sand concrete CGM high-strength non-shrinkage grouting material and aggregate mixture ratio of the actual water consumption. For the same strength grade between the variation of activity of cement, but by rapid determination of mortar strength test, adjustment according to the activity of cement concrete proportion of CGM high-strength non-shrinkage grouting material. Concrete CGM high-strength non-shrinkage grouting material of cimc is commonly referred to as broken ( Eggs) Stone, sand thickness of aggregate, etc. Only under the condition of the accords with a requirement to ensure their quality, the quality of concrete CGM high-strength non-shrinkage grouting material can be guaranteed. But most site construction mixing conditions cannot be compared with mixing condition of laboratory, especially the personnel quality. If only care about feeding and neglected the material moisture content and silt content, virtually to the error of the inventory of mixture ratio design, thus affecting the quality of the concrete CGM high-strength non-shrinkage grouting material, so we must to test before feeding raw material inspection, to determine reasonable inventory. The coarse aggregate mainly test the moisture content, grading and whether the needle flake content exceeds bid, to appropriately adjust the mixture ratio design; Of fine aggregate mainly test the moisture content, silt and clay pieces. Content of silt soil, the size of the CGM high-strength non-shrinkage grouting material of concrete strength, the silt content, the greater the CGM high-strength non-shrinkage grouting material of concrete strength value is lower, especially to the end of a time limit for a project, and set the field of soil mixed with easily being put in fresh concrete aggregate CGM high-strength non-shrinkage grouting material used in, therefore CGM high-strength non-shrinkage grouting material of concrete mixing station to choose good aggregate pile location, to prevent the soil mixed with sand and gravel aggregate.
