초록
In this study, ordinary and low-heat Portland cement and ordinary Portland cement were used for experiments and the air gap was minimized by using minute quartz as a filling. Additionally, a steel fiber was used to solve the brittle failure problem observed at high-intensity stresses. This study aimed to make an ultra-high strength powdered concrete, which has a compressive strength above 400 MPa. Ultra-high strength powdered concrete, which is different from the original concrete, is highly influenced by the materials used. In the study, the following had an effect on the compressive strength : ferro silicon > bauxite > dolomite > silicon. According to the SEM results, C-S-H hydrate was made in the highest quantiy, and tobermorite and zonolite were made by high temperature and pressure curing, respectively. In this study, ultra-high strength powdered concrete, which has a 28th day compressive strengthedof 420 MPa, has been successfully made.
