Mixed antifreeze beautiful seam an agent CGM high-strength non-shrinkage grouting material quality control

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material price CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material after casting, the structure is relatively weak job frozen parts, insulation antifreezing measures should be strengthened, and should be at the site of the typical parts or easy cooling temperature measuring point, temperature measuring head buried depth should be 100 ~ 150 mm, can also be used for the thickness of the 1/2 or half of the wall thickness. Before reaching seas critical strength should be every 2 h temperature measuring time, once every 6 h after test, and should be measured temperature at the same time. Mixed antifreeze beautiful seam an agent CGM high-strength non-shrinkage grouting material quality shall meet the requirements of planning, and shall meet the following requirements; 1, should be made in casting address must be the number of CGM high-strength non-shrinkage grouting material specimen strength experiments. Meantime a set of specimens shall be under the condition of the standard maintenance, the rest are placed in maintenance engineering conditions of 28 d, 28 d shall be to standardize maintenance for pressure testing. 2, the specimen shall not be under the frozen pressure testing, side length is 100 mm cube specimens, should be in 15 ~ 20 ℃ indoor frozen 3 ~ 4 h or should invade 10 ~ 15 ℃ water freezing of 3 h; Length is 150 mm cube specimens should be in 15 ~ 20 ℃ indoor frozen 5 ~ 6 h or hacked into 10 ~ 15 ℃ water freeze 6 manufacturer supply grouting material price h, dry after hydraulic test specimen. 3, check the specimen used in frost resistance, impermeability, 28 e maintenance should be with engineering conditions, to standardize the CGM high-strength non-shrinkage grouting material maintenance after 28 d antifreeze sleeve grouting material supplier or permeability experiment.
