CRITICAL REVIEW ON STRUCTURAL LIGHT WEIGHT CONCRETE

Concrete is widely used material across the world for construction of large structures. Due to increase in industrialization and development of urban areas, high volume of resources is required which are available naturally. This means high volume of resources is used worldwide for production of concrete. To reduce the use of such resources and to decrease the negative impact on environment, the uses of industrial waste and artificial aggregates as a replacement of natural aggregates are increasingly used. Another focus required in material research is to reduce the concrete weight density so that the effective dead load and seismic loads can be lowered. The paper attempts to review the literature and present a state of art in making lightweight concrete as reported till now for structural application
