This book offers a complete diagnosis of concrete samples collected from a pile cap block of residential buildings affected by internal swelling reactions.

This book discusses the effects of soluble mineral salts on ceramic brick masonry walls in Petrolina, a city in Pernambuco, Brazil, located 780 km from the ocean.

This book provides valuable information on polymer composite manufacturing, with a focus on liquid molding processes and the resin transfer molding technique (RTM). It presents and discusses emerging topics related to the foundations, engineering applications, advanced modeling and experiments regarding the RTM process.

This short book provides an update on various methods for incorporating phase changing materials (PCMs) into building structures. It discusses previous research into optimizing the integration of PCMs into surrounding walls (gypsum board and interior plaster products), trombe walls, ceramic floor tiles, concrete elements (walls and pavements), windows, concrete and brick masonry, underfloor heating, ceilings, thermal insulation and furniture an indoor appliances.Based on the phase change state, PCMs fall into three groups: solid-solid PCMs, solid-liquid PCMs and liquid-gas PCMs. Of these the solid-liquid PCMs, which include organic PCMs, inorganic PCMs and eutectics, are suitable for thermal energy storage.The process of selecting an appropriate PCM is extremely complex, but crucial for thermal energy storage. The potential PCM should have a suitable melting temperature, and the desirable heat of fusion and thermal conductivity specified by the practical application. Thus, the methods of measuring the thermal properties of PCMs are key.With suitable PCMs and the correct incorporation method, latent heat thermal energy storage (LHTES) can be economically efficient for heating and cooling buildings. However, several problems need to be tackled before LHTES can reliably and practically be applied.

This book presents a critical review of a criterion of risk, created to assess the flood risk to heritage buildings, and evaluates this criterion by applying it to the sample Portuguese heritage buildings.

This book discusses the effect of different school building rehabilitation strategies on the classrooms' indoor environmental quality (IEQ) and presents a multi-objective methodology for school building enclosure optimization combining artificial neural networks and lifecycle costs.
