Two-Stage Concrete As A Sustainable Production, Hakim Salem Abdelgader, Ali Said Ahmed El-Baden, H. A. Abdurrahman, A. S.M. Abdul Awal

Mechanical and Civil Engineering Faculty Publications

Two-stage concrete (TSC) is a sustainable concrete which is produced by forcing a flowable cement grout mixture through the voids of a skeletal mass made of compacted preplaced aggregates. From the technical and economic aspects, TSC is particularly useful for construction and repair of concrete structures especially foundations, underwater construction, nuclear reactors, concrete dams, heritage structures and in constructions with closely spaced reinforcement. TSC differs from ordinary concrete in that it contains a higher proportion of stone aggregate and the aggregate stays in point-to-point contact as placed. Thus, the mechanical characteristics of the TSC in failure conditions are distinctly different …
