Experimental Study on Recycled Concrete Aggregates Mixed in Concrete

Abstract

Concrete has been a leading construction material since its first use and will definitely retain its key role in the future due to its durability, free service health care, adaptability to any situation and size, various structural properties and cost-effectiveness. Concrete is the most important building material used in the area. It is a composite product obtained by mixing cement, water and an inert matrix of sand and gravel or crushed stone. Many activities, such as travel, storage, congestion, and treatment, are performed. The dividing material of concrete is the ability to harden underwater. Ingredients can be divided into two groups namely active and inactive. The working group contains cement and water, while the working group contains fine and strong aggregates. The inactive group is sometimes called the inert matrix. Concrete has a high pressure but its strength is very low. One of the biggest challenges for our current society is to protect the environment. Some of the key issues in this regard are the reduction of energy use and natural resources and waste management. These topics are receiving a lot of attention under sustainable development these days. The use of recycled compounds from construction waste and demolition reveals how it will be used in construction as an alternative (natural) compound. It conserves natural resources and reduces the amount of space required to dispose of waste. Any building project requires a number of materials such as concrete, metal, bricks, stone, glass, clay, mud, wood, and so on. However, cement concrete remains an important building material used in the construction industry. To be suitable and adaptable to the changing environment, concrete must be consistent in order to conserve resources, protect the environment, save and lead to efficient use of energy. To achieve this, much attention should be paid to the use of waste in the concrete used for new construction. Large quantities of demolished concrete are found in various construction sites, now causing a major problem for dumping in urban areas. This can also be easily applied as a composite and applied to concrete. Research and Development activities have been taken around the world to prove this practicality, economic efficiency and cost effectiveness.
