| Popis: | 83 In accordance with the conventional concrete mix design, a high cement conten is an important factor required in the production of high strength concrete. However, the test results of concrete made with the dry-mix ∕steam-injection procedure indicate that concrete made with a low cement content ( 250 kg/m^3 ) exhibits a high strength in an order of 60 MPa comparable to those of high strength concretes made with the wet mix procedure. It is therefore, envisioned that the conventional wet mix method may be improved to make high strength concrete with a low cement content. The proposed research will be carried out in two phases involving a theoretical study and an experimental test. In the first phase, the Kennedy material constitution law and the surface area method will be examined to optimize the mix design. In the second phase, different admixtures such as superplasticizers, water reducing agents and supplemental cementitious materials will be recorded, of which the data will be carefully studied to develop an effective mix technique. The objective of the proposed project is to conduct a feasibility study on minimizing the cement content in manufacturing high performence concrete. In order to provide useful reference for maintainable research and applied development, it is appropriate to figure out a mix proportion -ing method for high performence concrete with a low cement content through analyzing he test results . |
