1.1 Back ground of the research
Concrete is known as a construction material which is widely used throughout the entire world. According to the research, concrete contains Portland cement and it is an essential element to concrete (Naik and Moriconi, 2010). This essential element is capable of releasing carbon dioxide significantly. As carbon dioxide is known to be a green house gas, hence it can be said that this type of concrete is damaging the environment. In order to save the environment a new technology is made by which eco – friendly concrete can be made. Such concretes are made of the concrete wastes that are known to be eco – friendly; therefore, the concrete is also eco – friendly. This type of concrete is also known as green

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
What is concrete. According to Concrete Network (1999) “Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar”. The Roman's did it a little
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

From the ancient time marble is one of the most important materials used especially for decorative purposes. However its powder has bad effects on the environment, soil, water and health problems. Marble powder is produced from processing plants sawing and polishing of marble blocks. Some factories have water recycling plants containing flocculation tank and filter press unit. About 25% of the processed marble is turn into dust or powder form. About 7,000,000 tons of marble have been produced in the world. Disposal of the marble powder material of the marble industry is one of the environmental problems worldwide today. The refining of some fresh and hardened properties of concrete is successfully and economically achieved by utilizing and
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
Road is important a route, that connect two places that has been paved. Pavement road is road design for vehicles to go on it. There are many types of rad such as municipal road, federal road, and much more. Road design with two lane for two-way direction for the not busy area. Road with three or more lanes is known as highways. Design of Highways and roads request enormous amounts of materials for their construction. The need for earth-based materials makes impacts of energy consumption, resource depletion and natural degradation. (5) (McEntire, 2004). thus, to preserve nature we can use glass cullet to replace a certain amount of natural aggregate as sates by Finkle & Ksaibati in their study Recycled Glass Utilization In Highway Construction.
Properties of concrete are governed not only by the properties of its ingredients (cement, water, sand, and coarse aggregate) but also, to a great extent, by the relative proportions of these ingredients. The proportions must be so selected as to produce a concrete mixture of desired workability, strength, durability, and economy.
Concrete is one of the most important materials to build a building. Most of people refer to cement when hear the word “concrete”. In case, the cement cause some utility problem. The main problem is to produce 1 ton of cement, it also produce 1 ton emissions. This condition triggers the scientist to solve the problem. From many years of study, then they found out the geopolymer concrete. Actually this isn’t new structure, geopolymer had been used since long time ago. The objective of this research is to show that geopolymer has been proven for its strength, and this research will show the elasticity modulus to ensure whether geopolymer concrete is suitable for each building or
On the other hand, there are concerns that come with conductive concrete. Those concerns are about the economic feasibility and environmental impact of the application of conductive concrete. When it comes to environmental impact, conductive concrete would only be positive. It eliminates the need for traditional methods of deicing, such as plowing, natural melting, traffic movement and chemical treatment. The traditional methods also have a negative impact on their surroundings, “Applying chemical
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.
At present, the number of construction waste has accounted for 30% to 40% of the total municipal solid waste. The vast majority of construction waste without any treatment, it was using open dumps or landfill processing manner, causing serious environmental pollution. According to Wang (2014) mixed waste Concrete as the most important part of the construction waste, by estimating the amount of waste in 2003, China has reached 180 million tons of concrete. It has caused a great negative environment impact. At the same time, concrete production requires a lot of sand and gravel aggregate, as natural Gravel continuous exploitation of natural aggregate resources will also become exhausted, in addition, the exploitation cost astonishing transportation fees and power , it will also cause ecological environment experienced a serious damage. However, Make full use of recycled aggregate concrete, not only can effectively reduce the amount of construction waste, but also reducing the damage of construction waste pollution to the natural environment, while taking advantage of waste aggregate manufacturing recycled aggregate concrete can reduce the exploitation of natural aggregate, reaching the aim of sustainable environment development. However, due to there are some technical limitation, the implementation of using recycled concrete cannot be popularized into the civil engineering. For example, on the performance of durability, frost-resistance, and water absorption existed
construction and backfilling processes in order to minimize the usage of natural aggregates and land filling and 5) heavy building materials with high thermal mass will result in less energy consumption and fewer carbon emissions. Nonetheless, Nielsen (2008) did not take into account other greenhouse gases that constitute a considerable amount of equivalent carbon dioxide as methane, nitrous oxide, and fluorinated gases. Valipour et al. (2014) proposed Zeolite material which is considered as a type of natural pozzolanic material. The use of this material in concrete decreases the global warming index compared to conventional concrete. They concluded that replacement of 10%, 20% and 30% of cement with Zeolite would decrease global warming
