This thesis studies the effects of superplasticizers, polyacrylate latexes and asphalt emulsions, which differ in molecular/particle size from nanometers to microns, on the rheological properties of fresh cement pastes (FCPs), as well as the action mechanisms involved. It systematically investigates the rheological properties and microstructure of cement-based materials, and elucidates the adsorption behaviors of polycarboxylate polymers with different functional groups and their effects on cement hydration. Moreover, it reveals how the working mechanism of naphthalene sulfonate formaldehyde (NSF) differs from that of polycarboxylate ether-based (PCE) superplasticizers. Lastly, it develops a conceptual microstructure model and two rheological equations. These findings lend theoretical support to the development of new chemical admixtures and new, higher-performance, cement-based composites.

Residents look at their neighborhood differently than visitors and designers do. The features that they see as most important can differ significantly, so that spaces that are viewed as successful by designers may be disliked by residents. Designers who hope to create successful residential environments can benefit from a more complete understanding of the residents' perspective and their priorities. This residents-eye-view is especially critical in troubled neighborhoods.

Brower compares the responses to the same environment by residents, tourists, and designers. Using observations, interviews, innovative survey methods, and an examination of the literature, he details accepted norms that govern who uses and controls neighborhood spaces, children's play networks, neighboring patterns, territorial behavior, and the personalization of space. Brower then describes the application of these ideas and findings in a series of design interventions in an inner city neighborhood in Baltimore. These interventions are thoroughly documented and evaluated, and the lessons learned from both successes and failures are used to inform design ouidelines for the study area. The interventions also help to define the role of outside professionals; in particular, the importance of involving residents in defining and resolving their own problems, and the need to accept space management and social organization as proper concerns of design. The book is written in clear, simple language, and uses drawings and photographs to illustrate the ideas presented.

Concrete is the second most used building material in the world after water. The problem is that over time the material becomes weaker. As a response, researchers and designers are developing self-sensing concrete which not only increases longevity but also the strength of the material. Self-Sensing Concrete in Smart Structures provides researchers and designers with a guide to the composition, sensing mechanism, measurement, and sensing properties of self-healing concrete along with their structural applications

Fundamental environmental challenges such as climate change, resource depletion, and pollution are still widely relevant in today's world. Many of these problems have been associated with the architecture, engineering, and construction industries due to the level of resources used in these professions. In recent years, many manufacturers in these fields have expressed the motivation to make necessary changes that would be beneficial to the environment. Despite this progress, there remains a lack of research and assessment on the methods to achieve environmental stability within these architectural fields. Examining the Environmental Impacts of Materials and Buildings provides emerging research exploring the theoretical and practical aspects of ecological performance within modern building design and materials-based construction. Featuring coverage on a broad range of topics such as life cycle assessment, material flows analysis, and sustainability, this book is ideally designed for architects, civil engineers, construction professionals, environmentalists, ecologists, business practitioners, scientists, policymakers, designers, researchers, and academicians seeking research on current trends in environmental performance within building design.

This book reports on the physical and mechanical characterization of Recycled Aggregate Concrete (RAC), produced through a partial-to-total replacement of ordinary aggregates with what have been dubbed Recycled Concrete Aggregates (RCAs). It proposes a theoretical framework for understanding the relationships between RCAs and RCA, and for predicting the resulting behavior of RAC. The book demonstrates that in the case of RAC two additional parameters have to be taken into account than with ordinary aggregates, due to the composite nature and higher porosity of RCAs. By extending Abrams' Law for Recycled Aggregate Concrete, it represents a first step in the formulation of a general model for predicting the properties of RAC. The theoretical approach presented here addresses an important gap in the literature and is expected to stimulate new research on the use of this more sustainable form of concrete in structural applications.

This thesis studied the effect of aging of intumescent coatings (ICs) on the reliability of protected steel columns in fire condition and developed a probabilistic approach to assess the service life of ICs applied on steel columns. In the study, Monte Carlo simulations were conducted to obtain the reliability index or failure probability of steel columns protected by ICs subjected to compartment fires. The effect of aging of intumescent coatings on the failure probability of protected steel columns was investigated by using variable insulation property of intumescent coatings in the simulation. The test data on aging effect on insulation property of intumescent coatings from literature was used. Based on the reliability analysis, a probabilistic approach is given to determine the service life of intumescent coatings for steel columns. In that approach, the failure probability of the protected steel columns is compared with the target probability of the structural fire design. The approach can also be used for probabilistic analysis of steel columns protected by conventional inert fire protection materials.
