Preparation and fundamental of mechanical properties of super high strength concrete
Coarse aggregate is removed as a common practice when super high strength cement-based materials of more than 150 MPa, such as RPC, MDF, and ECC, are prepared. This is because the deformation of harden paste is different from that of coarse aggregate, which gives rise to defect increasing of the concrete product. Without removing coarse aggregate, this paper focuses on the preparation of super high strength concrete, which had compressive strength of 178.3 MPa at 365 days and slump of 210 mm when common technology and ordinary materials were used. Based on the analysis of effectiveness factor for micro-structure and micro-mechanics, the fundamental of mechanical properties of super high strength concrete are discussed.
