Recycled Concrete Aggregate and the Need for Sustainability

The interest of including sustainable development in construction is on the rise due to the changing systems of the world based on its economy, its environment and society. The most immediate and obvious way to achieve more sustainable construction today is by conserving new raw materials such as natural aggregates, and reusing construction and industrial wastes. For those who may not know, recycled concrete aggregate, better known as RCA, is an example of a common construction waste that is produced after demolishing concrete structures. Technical Data used in the field explained in civil surveyor course in rawalpindi. Supplementary cementing materials (SCM) such as fly ash and slag are industrial by-products, which have a long history of use with Portland cement (PC) in concrete.

Although Portland cement is the primary source used for construction, it has been found that it is no longer feasible and the continuation of its usage will no longer supply benefits in cost management and will further deteriorate the environment, consequentially impacting global society. The study of recycled concrete aggregate is interesting because it is a new mechanism used that could potentially impact society as a whole, economically, environmentally and socially. Some more details of civil surveyor course in rawalpindi are as under. The aim of this article is to examine and provide an analysis of the technology used when recycling concrete aggregate, instead of using virgin aggregate, as is the current procedure in Canada.

Due to the high urbanization of many cities in Canada, concrete is one of the most popular construction materials used in the country. Environment Canada has identified that two thirds of the concrete's production is used in basement's foundations for commercial and residential constructions. The basic components that produce concrete are aggregates, cement, water and some chemical admixtures. Concrete consists of 75% of the weight of all construction materials. Interestingly, construction and demolition waste in Canada amounts to 15-20% of all landfill materials. Due to the increase in waste in general, there needs to be a mechanism in places where waste can be reduced and one place is within the process of recycled concrete aggregate. By finding new applications for concrete waste, and creating a market for its use, we can bypass the need to consume virgin natural aggregate and simultaneously conserve landfill space.
