| Abstract: | In the mine construction,pumping concrete is widely used in the cast-in-place structure,following with the cracks problem in the early stage as focus.In this paper,the characteristics of ready-mixed pumping concrete construction and reasons for the cracks are discussed.Moreover,the coutermesures are put forward from the point of view of raw materials and construction techniques.This will play a guiding role to predicate and control cracks in the mine construction |
