15 years dong shi technology: CGM high-strength non-shrinkage grouting material construction under negative temperature should be attention

CGM high-strength non-shrinkage grouting material CGM high-strength non-shrinkage grouting material manufacturer CGM high-strength non-shrinkage grouting material price as the saying goes, 'do not move to 1929, the 3949 walk on the ice', has been at the coldest time of the year, then under negative temperature CGM high-strength non-shrinkage grouting material construction should pay attention to? Whether in SanJiuTian stop construction? Comprehensive consideration; Whether negative temperature under construction should be in accordance with the local average temperature and decide, when outdoor, the average temperature is below 5 ℃ for 5 days, winter construction of production measures should be taken; The lowest temperature is lower than 0 ℃, should stop construction of the normal concrete. Using CGM high-strength non-shrinkage grouting material construction maintenance measures is material engineering required. Construction points: under negative temperature in winter construction, after pouring CGM high-strength non-shrinkage grouting material compressive strength value must be greater than 25 mpa, just can have the ability to withstand freezing injury. That is to say, before the strength not reached 25 mpa, must be prepared to hubei grouting material wholesale winter construction of heat preservation, moisture and maintenance work. Negative temperature under construction conditions: the condition of four word 'thermal insulation'. Warm refers to the construction site, construction parts and materials piled up. Insulation refers to: environment after casting, the casting body heat preservation measures. Thermal insulation is grouting material and shi winter a very important measure. When applied to the specific requirements of the thermal conditions in winter there are many kinds of protective measures and method, its purpose is to: use of the existing of CGM high-strength non-shrinkage grouting material mixer, adjust measures to local conditions, the construction site ( Operation) , casting parts, the temperature of the material, its reach more than 0 ℃, warm conditions, it is a winter antifreeze, antifreeze type grouting material can be in - After 15 ℃ under the environment of construction, construction must be the heat preservation and maintenance. In winter construction of grouting material engineering, water added must be strictly controlled. In addition, the winter of grouting material not to mixing grouting material inspection standards into any component antifreeze seam an agent. Because the material is configured itself has joined antifreeze, antifreeze, aggregate, when mixed with other materials will directly influence on the performance of the grouting material specific technology, can bring serious hidden danger to the engineering quality.
