Concrete waste is one of the highest proportions of the total construction and demolition materials. Most of the concrete waste generated is sent to landfills. Part of the concrete waste is used as recycled aggregate for producing recycled aggregate concrete; however, recycled aggregate concrete is only used on a limited...Read More

The rapid urbanization around the world has created shortfall of conventional building construction materials and put a lot of stress on the natural resources, which are getting scarce. Also the disposal of industrial, agro and other solid waste is another serious issue of concern in developing countries. To minimize the cost...Read More

Cement Production and its environmental impact. This chapter deals with cement manufacture, cement properties, types of cements, blended cements and life cycle assessment of different types of cements. Cement is one of the most important building materials around the globe. It is used mainly as binding and strength giving medium...Read More

Exposure to severe temperatures is one of the critical effects on concrete damage. Additionally, the aggregate porosity (pores in the range of 0.1–0.5 μm) is the characteristic that influences freeze–thaw resistance due to the pore saturation resulting in the concrete deterioration. Freeze and thaw is a durability property which is the...Read More

Properties of recycled aggregate concrete (RAC) were found to be dependent on the source, its composition and consistent quality of demolished concrete waste. Many studies have shown that using recycled aggregate (RA) in concrete suffers from strength and durability problems caused mainly due to relatively porous residual mortar adhered on the surface...Read More

With the goal of achieving sustainable development, numerous research studies have been conducted aimed at reducing construction and demolition waste for improving sustainability and environment and reducing greenhouse-gas emissions.  Recycled concrete aggregate due to its residual adhered mortar has low specific gravity and high water absorption. Both of these impediments contribute in the increase...Read More
