Rapid industrialization and the need for built space and constructed facilities in hostile and aggressive environmental regions necessitated a quantum jump in the performance of the construction materials. The bricks one of the largest used materials in construction today occupies a pride place. Therefore, the production of high quality and a ordable blocks/bricks is paramount to solving housing problems in developing countries. Thus, this book focused on design construction and testing of a brick making machine that produces quality bricks for low cost housing. This book presents the introduction to such masonry units through its manufacturing process and experimental work by performing compression test, water absorption test, cost feasibility and comparing it with the conventional clay bricks.
For the partitions of the building one cannot ignore bricks due to its lesser cost and flexible use. These walls are subjected to lateral loads induced by wind and inertia load produced by horizontal ground motions during an earthquake. An alternate to reinforced cement concrete water tank is a brick wall water tank, a permanent fixture of every residential house due to negligible water supply from municipal corporation. As a solution to this practical problem an effort has been made to investigate the effect of bond on the strength of brick wall subjected to lateral load. Wall panels have been constructed using English & Flemish bond. On the application of lateral load upto ultimate state the experimental study reveals some good results. Load deflection response indicates a linear relationship upto first crack load. Wall behaves elastically upto first crack, and on further increase in load due to the difference in stiffness of masonry unit and mortar (low tensile bond strength) the crack propagated and at ultimate state crushing took place followed by large central deflections.
The cost of housing has increased in recent years, posing great challenge to the engineers. By the use of traditional materials and construction methods alone, it will not be possible to construct houses at a pace matching the ever increasing demand. There is an urgent need for reducing the cost of construction by adopting some innovative techniques using traditional materials. Fired earth brick is the most popular low cost building material used in many part of the world. Some innovative techniques like the construction of brick masonry cavity walls and 190 mm thick reduced thickness wall by using the conventional solid bricks have been proposed in the recent years. Though considerable saving in the cost can be achieved by such techniques but its adoption in practice requires thorough understanding about their mechanical properties and the response of such structures to lateral loads especially the earthquake forces. This book is aimed at attaining these objectives so as to provide a rational design basis for such low cost buildings. This book is useful for researchers, practicing engineers, teachers and students who are working in the area of Civil Engineering.
