Comparison of Plain Concrete and Lightweight Concrete and Their Impact on Climate Change

The building sector accounts for approximately 30–40% of national CO2 emissions from the use of fossil fuels. As construction activities both consume energy and cause environmental pollution/emission of greenhouse gases they consequently lead to climate change. Buildings are responsible for % 40 of total energy in their life cycle stages of buildings in the world and for one third of global greenhouse gas emissions as well, in developed and developing countries. Proper technologies and strategies would play main role to reduce embodied carbon. Besides, quality of raw material, production processes, design of buildings, development level of countries, use of local materials, transportation of produced materials. In recent years in Kosovo we have an extreme increase in air pollution and pollution of nature and natural resources. Therefore, awareness has been raised about the consequences of environmental pollution as well as the negative consequences of various human activities and various technological processes in the environment. Therefore, these phenomena caused increased interest and commitment in the study of these about the impact of these effects on climate change, water, air pollution, soil and ecosystem degradation. Sustainable development in construction engineering is generally based on reducing the use of energy and natural resources, reducing pollutant emissions to soil, air and water, increasing the sustainability and service life of structures, the use of by-products, recycling and reuse of products various which are used in civil engineering from production to their implementation in construction. In Kosovo in the last decade there is a rapid development of construction and large investments in infrastructure. One of the most used materials is Concrete which has a great use in construction, infrastructure and other sectors of civil engineering. The concrete industry is a major consumer of natural resources (aggregate, clay, lime and water) and has a major impact on the environment. Many scientists are engaged in finding alternative ingredients for concrete preparation in order to save natural resources, the importance of finding and accepting the use of alternative ingredients for concrete is clearly of particular importance about the impact of these effects on changes climate, water, air pollution, soil and ecosystem degradation. One of the main products in the preparation of concrete is aggregate, the consumption of natural aggregate as the largest component of concrete is constantly growing and with great speed, the use of alternative sources of aggregate based on this construction trend is inevitable. In the construction engineering in the last decade there has been a very high demand for the application of lightweight concrete, in order to achieve greater height and reduce the weight of construction structures. Therefore, different materials have been analyzed and lighter in weight than the aggregate, which has made it possible to replace the natural aggregate. In this paper is analyzed the impact on climate change, water, air pollution, soil and degradation of ordinary concrete ecosystem and concrete to be allowed by the preparation of concrete transport and placement in the facility. Two elements of the structure were taken for analysis and analyzed from the recipe to the final product
