To eliminate cracks grouting material technology Xi 'an equipment foundation grouting material

Equipment foundation grouting equipment foundation grouting material factory equipment foundation grouting material price 1, beam-column node equipment foundation grouting material shall implement the principle of 'first after the high low, namely first casting equipment foundation grouting material, high strength grade after pouring equipment foundation grouting material of low strength grade. In the high and low strength grade a border of equipment foundation grouting material, set up the wire mesh, so that the operator easy to control equipment foundation grouting material casting range.         2, high strength grade routine equipment foundation grouting material mixture ratio adjustment, namely under the condition of satisfy the intensity and the pumpability, try to reduce dosage of cement, sand ratio, increase the gravel content, reduce slump, reduce their mortar and equipment foundation grouting material consumption, and the dosage of fly ash and plus the seam an agent also make corresponding adjustment, to try to reduce equipment foundation grouting material hydration heat temperature, reduce because of the different strength grade equipment foundation grouting material shrinkage or equipment foundation grouting material cracks caused by temperature difference between inside and outside.         3, beam of equipment foundation grouting material using secondary pouring method, namely in the equipment foundation grouting material before final set casting again, especially in the butterfly lovers node, in order to increase the compactness of equipment foundation grouting material, reduce shrinkage.         4, in easy to produce cracks in beam profile increase the level of structure reinforcement, improve crack resistance of beam.         5, strict control of equipment foundation grouting material mixture slump, at the scene of the quzhou equipment foundation grouting material manufacturer for every car equipment foundation grouting material, slump test, found abnormal, immediately return, and make records, prevent it from spent big slump for equipment foundation grouting and cause shrinkage crack. ​
