Green Concrete Advantages And Disadvantages

A specific subset of recycled aggregates is recycled concrete aggregates (RCA) where the masonry content is limited to not more than five per cent. The performance characteristics of RCA are better than RA and consequently there are fewer restrictions on the use of RCA in concrete (BS 8500-2)

Concrete has many effects on the environment. Concrete damages topsoil which is the most fertile layer of soil. Concrete also contributes to surface runoff, erosion, and pollution. Concrete is helpful for preventing floods by building dams. I think that using concrete is good because while it does create runoff while used in roads it won't when used in a monument. And even though it damages soil it will not matter because their are no farms in the city.

Green Buildings can help the earth in so many ways. Being certified means that you build more environmentally friendly, which means that building green friendly can reduce the negative effect buildings and operations have on the environment. Also green building greatly decreases the chances of fire, explosions, spills or splashes. Building green also reduces health problems such as allergies.

Green buildings could become one of the main factors to preserve our rapidly decaying environment. There is no easy way to define a green building, but a green building is essentially a structure that amplifies the positives and mitigates the negatives throughout the entire life cycle of the building (Kriss, 2014). There are many definitions for a green building, but all of them include the planning, designing, constructing, and operating of the building while taking into huge considerations of the energy use, water use, indoor air environment, materials used and the effect it has on the site the green building is being built on. The first green buildings dates back to as far as the 1970’s, when solar panels went from experiments to reality. Green buildings were not as popular as they are today due to their extremely high pricing. With technology rapidly growing, solar panels are becoming cheaper and cheaper, making the transition to creating green buildings more affordable. This is the primary reason for the increased growth of green buildings today. A modern company that is paving the way to the growth of green buildings named LEED, Leadership in Energy and Environmental Design, focuses primarily on new and effective ideas for environmentally friendly buildings projects. With more than 60,000 commercial projects worldwide and 1.7 million square feet being certified every day, LEED is one of the leading groups for promoting green buildings. LEED has popularized the entire

First, concrete durable. Concrete is something that will outlive other products up to three times over (“What Makes…”). In addition to durability, concrete is efficient. Concrete can be made with byproducts from power plants, and other aspects of manufacturing. Concrete is primarily made up limestone, the most abundant material on Earth. Above all of this concrete can be recycled. Concrete can be crushed and recycled into another structure or product, reducing the need to mine the limestone for production. Concrete also allows water to pass through which reduces the chance of flash flooding, erosion, and water table depletion as compared to other materials. This is a major check in the sustainability of concrete; the conservation of soil, landscape and ecosystems. Concrete is a very green option when it comes to building

The Development of Concrete

Concrete has been used to build roads in America; although this is an expensive alternative to asphalt, it holds more advantages than normal asphalt. Concrete is more durable than normal asphalt and is capable of giving drivers better gas mileage. Concrete roads have also been proven to be more skid-resistant with the addition to grooves to the concrete. It can also help drivers save more gas money since it’s been proven to be fuel efficient. With the advances of modern science, scientists and concrete manufacturers have created some ways of creating concrete in a cheaper way so it can be used more often in creating

In order to discuss concrete; one must first mention cement. Cement is a water-based binder used to bind other building materials together. It is used in the production of mortar and concrete during the construction process. Concrete is a material used in construction, made by mixing aggregate, cement, small stones and water. Cement is important because it hold structures together. Many sources states concrete was invented 1756 by a British Engineer named John Smeaton. He did so by mixing pebbles as a coarse aggregate into a powdered brick into the cement. Years layer in 1824, a English inventor named Mr Joseph Aspdin created the first true artificial cement by burning ground limestone and clay together. He is also noted for creating today’s popular concrete; Portland cement. Many buildings use concrete because of its strong element. It solidifies then hardens after mixing with water and placement due to the chemical process known as hydration. Water reacts with the cement, which bonds the other components together, eventually creating a stone-like material. Concrete is used to make pavements, pipe, various structures, foundations, roads, bridges, brick walls and so on. It is either produced site-cast or pre-cast. Site-cast Concrete is standard concrete that is poured into site-specific forms and cured on site; the concrete is created on the actually construction site. Precast concrete is a construction

Trying to decide which material to pave your driveway with can often be a confusing task when you consider that there are many different options available to you that can all prove to be very beneficial in their own ways. However, there are a few reasons to pave your driveway with concrete instead of those other options, such as the three listed below.

Manufacturers have incorporated cement everywhere, It's what many walks in, it's what supports buildings, and it’s even in a variety of houses. David Biello also mentions Lenny Bernstein, an environmental consultant and is also a leading coordinator for the IPCC, he says that energy efficiency

The definition of high strength changes over the years as concrete strength used in the field increases. Any construction activity requires several materials such as concrete, steel, brick, stone, glass, clay, mud, wood, and so on. However, the cement concrete remains the main construction material used in construction industries. For its suitability and adaptability with respect to the changing environment, the concrete must be such that it can conserve resources, protect the environment, economize and lead to proper utilization of energy. To achieve this, major emphasis must be laid on the use of wastes and byproducts in cement and concrete used for new constructions. The utilization of recycled aggregate

Millions of tons of fly ash is produced each year, with less than 50% of that total material being recycled and used in other applications. Fly ash is a fantastic substitute in the construction industry, supplementing the need to use a pure mix of Ordinary Portland Cement (OPC),

We all have a conventional roof, any of us use that roof other than shelter purpose? But this green roof has many benefits at environmental protection, social quality of life and economic development. in short benefits at sustainable development. A green roof contributes in storm-water management, reduction in heat island effects, reduction in pollution, provide habitat for plants, insects and animals, aesthetic benefits, reduction in noise level, fire prevention, energy savings ( reduction in energy bills) as well as the life of the green roof is twice than the conventional roof ( stater 2008; Kristin and D 2006; Amanda, Jim , Mcrae , Kathy , Michel 2014; Donald and Preethi 2010)

Concrete is one of the oldest and durable composite materials in building and construction engineering. Its importance cannot be overestimated. However, some of its traditional aggregates release a lot of carbon dioxide to the environment during production. In broadening the use of concrete as internal household design like countertops, exploiting the potentials of crushed waste glass as a substitute for the carbon dioxide emitting aggregate is reasonable step towards a greener and healthy environment.
