Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and 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 tional publishing house to assure improved service and broader dissemination. 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 34 (thesis year 1989) a total of 13,377 theses titles from 26 Canadian and 184 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. While Volume 34 reports theses submitted in 1989, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Porous concrete is becoming an attractive pavement solution due to its great performances in mitigating urban heat island (UHI) effect and managing storm water. As a heterogeneous material, the properties of cement-based porous concrete are complicated to quantify and hard to predict. This thesis focused on the evaluation of thermal properties and air void characteristics of porous concrete. The thermal properties of aggregates, cement pastes, and porous concretes were measured by transient plate method (TPS) and steady-state heat flow meter method, respectively. X-ray computed tomography (CT) technique was utilized and three-dimensional (3-D) pictures were treated to analyze the microscopic structure of air voids in porous concrete. The existing analytical models were employed to estimate thermal conductivity of pervious concretes and compared to experimental measurements. The tests results show that thermal conductivity and heat capacity of cement paste increases as water cement ratio increases. Meanwhile, for the same mix design, the thermal properties of different cement paste samples had few variations. However, the porous concrete is very heterogeneous and the same mix design cannot ensure the similar porosity; instead, significant variations of porosity were observed. The existing analytical results did not show satisfactory prediction results of thermal conductivity as compared to testing results. This indicates the existing models are not suitable to estimate the thermal conductivity of porous concrete. This is because the models ignore the complex microscopic structures of porous concrete. Based on the CT-scanned images, within the horizontal plane of cylindrical sample, slight differences of normalized projected lengths of air voids were observed in the orthogonal horizontal directions; while the normalized projected length of connected voids in vertical direction was found smaller than those in horizontal directions. The smaller aggregates tend to form the longer air void length in porous concrete. The curvatures of air voids for smaller aggregates are greater than that of larger aggregates. Meanwhile, within the same mix design, the curvature of air voids increases with the increasing of porosity. The porosity and aggregate size do not have significant influences on the ellipticity and tortuosity of air voids within porous concrete. However, with the increase of porosity, the air voids tend to have the greater equivalent diameter.

Book Description
This book presents the work done by the RILEM Technical Committee 227-HPB (Physical properties and behaviour of High-Performance Concrete at high temperature). It contains the latest research results on the behaviour of high-performance concretes at high temperature. The book presents the state of the art of experimental data on High-Performance concretes and it collects and synthesizes useful data about concrete behaviour at high temperatures. The book is divided into independent chapters dealing with degradation reactions in concrete exposed to high temperatures; mass transport properties; thermal properties; and mechanical properties. The results presented especially target a group of users composed by universities and testing laboratories, building material companies and industries, material scientists and experts, building and infrastructure authorities, designers and civil engineers.

Book Description
This volume on “Advances in Analysis and Design of Deep Foundations” contains 22 technical papers which cover various aspects of analysis and design of deep foundations based on full-scale field testing, numerical modeling, and analytical solutions. The technical papers are 8-10 pages long that present the results and findings from research as well as practical-oriented studies on deep foundations that are of interest to civil/geotechnical engineering community. The topics cover a wide spectrum of applications that include evaluation of the axial and lateral capacity of piles, pile group effects, evaluation of the increase in pile capacity with time (or pile setup), influence of excavation on pile capacity, study the behavior of pile raft caisson foundations, evaluate the bearing capacity and settlement of piles from cone penetration tests, etc. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.
