Grouting material beauty antifreeze agent selection shall meet the following requirements Nanchang grouting material

Nanchang nanchang nanchang grouting material manufacturer grouting grouting material price - nanchang grouting material manufacturer 158 - 3830 - 411. 1, the daily minimum temperature is - 5 ~ 0 ℃ nanchang high strength grouting material price, CGM grout material by plastic film and thermal insulation material to cover the curing time, early strength can be used the seam an agent or early strength water reducing seam an agent. 2, the daily minimum temperature is - 10 ~ - 5℃，- 15 - - 10℃，- 20 ~ - 15 ℃, using insulation cap measures, should be the specified temperature for - respectively 10℃，- 15 ℃ antifreeze beautiful seam an agent. 3, the regulation of antifreeze beautiful seam an agent temperature for CGM grout material beauty antifreeze agent ( jc 475) Test conditions prescribed by the shape of specimen, under the condition of constant negative temperature curing temperature. Construction using the lowest temperature than low temperature 5 ℃. Antifreeze seam an agent to the site ( Or CGM grout material batch plant) made by hua-dong works are First check whether there is precipitation, crystallization or caking. Inspection items shall include density, fineness, 7 d and 28 d compressive strength ratio, reinforcement corrosion test. Library, use. Mixed antifreeze beautiful seam an agent used raw materials, grouting materials shall meet the following requirements. 1, appropriate chooses Portland cement and ordinary Portland cement. Cement storage period more than 3 months, before use must strength inspection, qualified rear can use. 2, the coarse and fine aggregate must be clean and shall not contain ice, snow and freezing and frost crack material manufacturers selling grouting material manufacturer. 3, when aggregate alkali activity, the anti-freezing seam an agent into the beauty of the alkali content, total alkali content, grouting materials should comply with the rules. 4, storing liquid anti-freeze beauty seam an agent of equipment should be heat preservation measures. Mixed antifreeze beauty seam an agent of CGM grout material mixture ratio, should meet the following requirements. 1, are caused by components antifreeze beauty seam an agent grouting material of sand ratio, than not to mix with the seam an agent of grouting material sand ratio can be reduced by 2% the & # 12316; 3%. 2, CGM grout material water-cement ratio should not be more than 0. 6, cement dosage should not be less than 300 kg/m, important bearing structure, thin-walled structure of grouting material of cement can be increased by 10%, the mass grouting material minimum cement contents shall be according to actual situation. Strength grade is not greater than c15 grouting material, its water cement ratio and cement dosage is not restricted by the least.
