Book Description
The purpose of this investigation was to determine the combined effects of fly ash as a partial replacement for portland cement and the use of high-pressure compaction in reducing the porosity and increasing the compressive strength of prepared miniature compacts. According to current practice and theory, for specialized uses, portland cement concrete materials with strengths approaching 20,000 psi (140 MPa) may be produced by reducing the amount of porosity present in the microstructure of the paste-matrix material. To accomplish this, both high-pressure compaction and increased formation of cementitious products form a pozzolanic reaction have provided excellent results. However, judging from an extensive literature survey, the effect of combining the two has not been examined. The three main parameters investigated included the initial compacted porosity level from high-pressure compaction, the percentage fly ash replacement of the cement, and curing duration. Additionally, the effects of accelerated curing by oven-drying was explored. The study revealed that high-pressure compaction, followed by accelerated curing, is an excellent means of producing a low-porosity condition and, thereby, a greater strength in a cementitious material.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.
