摘要: Two reactive powder concretes (RPC) were produced on an industrial scale at the Universite de Sherbrooke and in a nearby precast plant. A 2.6 cubic meter mix was prepared central mixer of The ready RPC sampled before after addition steel fibers while one plant only end mixing process. These RPCs tested for compressive strength, modulus elasticity, freezing thawing cycling resistance, scaling resistance to deicing salts, chloride ion penetration. results show that 200 MPa strength could be achieved both cases: curing hot water 90 degrees C or low pressure steam chambers Confinement tube greatly increases its ductility.
