A Study on Delayed Deformations of an Ultra High Strength Cementitious Material

摘要

This paper presents the results of an experimetnal investigation of RPC (Reactive Powder Concrete) on shrinkage and creep under uniaxial compressive loading. The RPC are ultra-high strength concretes characterized by high silica fume content and steel fibers reinforcement. The present study focuses on RPC with a very low water/binder (0.17) ratio nad a compressive strength at 28 days of 160 and 200 MPa after a 90 deg C heat-treatment.
