Those changes on engineering properties for the concrete specimens (including the used paste amounts, unit weight, compressive strength, etc.) are researched by means of adjusting the fraction of pastes with various water-to-binder ratios as well as utilizing the graded aggregates with diverse aggregate size combinations. It is expected to develop a new type of production method, so as to alter the traditional production techniques for precast concretes. The characteristic of this method is that, for a start, the sealed mold is filled densely with normal aggregates and then the pastes are grouted into the mold with high pressure. Because of the hermetically sealed mold, as the process of high pressure grouting is employed, the pastes would be extruded and fill the voids among aggregates in the mold quickly. For this reason, the component materials could be bound tightly each other. The experiment results show that, the specimens made by this method could easily achieve the required high strength with the compressive strength ranging from about 55~70 MPa (8~10 ksi), and some even exceed above 70 MPa (10 ksi). Not only could the strength requirements for structural members be fulfilled, but also the complicated procedures for the conventional concrete productions are simplified adequately due to the production techniques totally different from those of traditional precast concretes. Therefore, a new type of production method with economic benefits, material usage efficiency, and automatized production procedures could be developed. 陳豪吉 2006 學位論文 ; thesis 58 zh-TW
