APPLICATION AND EXPECTATION OF HIGH STRENGTH CONCRETE IN SHAFT LINING

High strenght concrete is a kind of good quality architecture material,which has high strength,litter distortion and a penetrating-resistant character as well as a frost-resistant character.The use of high strength concrete in shaft lining of depth soil might meet with the constructive need of frozen and boring shafts.The high strength concrete composite shaft lining has excellent qualities of decreasing thickness,infiltration and cost in building shafts.In this paper,the experience obtained in making use of high strength concrete of Chinese mine shaft lining is introduced.The future composite shaft lining of high strength concrete structure forms have been suggested in order to be widely use of them and to solve the difficulty problem on supporting in depth soil shaft linings.
