Application of new green building materials in civil engineering

Abstract

About 50% of the world's energy consumption comes from the construction industry. At the same time, more than 60% of the raw materials that humans obtain from nature, such as wood, stone, sand, etc., are used to build various buildings. During the construction process, the processing of these materials can cause a large amount of pollution. For example, the production of concrete can cause an increase in greenhouse gas emissions. These phenomena urge us to improve and upgrade building materials to ensure that the basic functions of the building are achieved and its safety is guaranteed on the basis of minimum pollution. Therefore, green buildings have emerged and gradually received attention. This paper mainly introduces two new concrete materials (one is the concrete material produced by Carbicrete Company that can realize the negative emission of carbon in production and use, and the other is high-performance concrete material), photovoltaic power generation system that can be installed on various structures of buildings and new SiO2 aerogel building materials (mainly used in thermal insulation felt and concrete, which can ensure the heat resistance of materials while reducing the thermal conductivity).
