In the 1990s, sustainable development became the choice of many countries. In this context, the concept of green building has gradually penetrated into the hearts of the people. With the environmental protection products gradually becoming the leading role in the market, consumers put forward safety, health, low carbon and other requirements for building materials. It is an inevitable trend for the development of construction industry to popularize and apply green technology and use environmentally friendly building materials without pollution, pollution and radioactivity.
Causes of Pollution from Traditional Building Materials
With the continuous improvement of living standards, people pay more and more attention to the building environment. However, some traditional building materials are made of chemical materials and contain toxic substances. This building material continuously releases toxic gases into the room, which is harmful to human health. According to media reports, experts from the U.S. Environmental Protection Agency have sampled 10 new buildings. The test results show that there are more than 500 chemicals in the indoor air of buildings, many times higher than that outside.
The results show that asbestos and radon are present in 2%~3% of the houses, and viruses and bacteria are present in about 10% of the houses. Buildings with these harmful substances indoors are called “sick buildings”. These “sick” buildings will spread their “illness” to the users of houses. Facts have proved that all kinds of harmful substances released from inferior building materials are very harmful to human health. The high temperature in the enclosed building provides a favorable environment for bacterial reproduction and is more harmful to human body.
Application of Environmental Protection Building Materials
For a long time, we have always believed that China is a country with vast territory and rich natural resources. In fact, China’s per capita natural resources occupancy is far below the world average. How to make more Chinese entrepreneurs and ordinary residents realize the importance of energy conservation is worthy of everyone’s consideration.
Development of Environmental Protection Building Materials
Green building is a building that can effectively utilize resources, that is, energy-saving, environmental protection, comfortable and healthy building. The selection of building materials for green buildings should follow the following two principles: one is to use 3R (Reduce, Reuse, Recycle, reusable, renewable) materials as far as possible; the other is to select materials and products that are non-toxic, harmless, non-polluting and beneficial to human health, preferably with national environmental protection. Marking materials and products.
Compared with traditional building materials, new building materials can not only reduce building energy consumption, but also make rational use of industrial waste. New building materials not only do not pollute the indoor environment, but also benefit human health. They help to improve the building environment. They can play the roles of mildew prevention, sound insulation, heat insulation, sterilization, temperature adjustment, humidity adjustment, light adjustment, flame retardant and deodorization. The production process of new environmental protection building materials will not pollute the environment, will not generate new waste, and most of them can be recycled.
Judging from the market situation of our country, most enterprises do not know whether the building materials products they produce or sell conform to the national standards, let alone produce or sell building materials in accordance with the national standards.
With the development of modern society and economy, the scale of infrastructure and housing construction is becoming larger and larger. The large-scale production and use of building materials provide material guarantee for improving human living environment, but also pay the cost of excessive energy consumption and serious environmental pollution. Therefore, in order to protect the environment and achieve sustainable architectural design, the impact of raw materials on the environment must be included in the standard system to measure the value of buildings. Architecture comes from nature and returns to nature. The materials used should not cause harm to human body and the surrounding environment. Taking clay brick as an example, its production process will destroy the soil environment.
From the perspective of sustainable development, timber should be used more cautiously in construction. Cutting down trees in large quantities will lead to a series of problems, such as increasing transportation energy consumption, destroying local economic environment and ecological environment, etc. Environmentally friendly buildings should have outstanding durability, be easy to maintain and manage, and release little or no harmful substances. In order to achieve the goal of sustainable development and minimize the negative impact of building materials on the environment, it is necessary to develop pollution-free construction technology and environmentally friendly building materials. For example, the use of industrial waste (fly ash, slag, coal gangue, etc.) to produce cement, building blocks and other building materials, the use of waste foam plastic to produce insulation wall panels, the use of waste glass to produce veneer materials. This method can not only use industrial waste, reduce environmental pollution, but also save natural resources.
Energy-saving and environmental protection materials will become the mainstream in the future
Energy-saving and environmental protection materials have been widely used in the field of construction, and will become the mainstream of the market in the future. It is understood that Europe has set off a wave of architectural revolution. Houses in the future are expected not only to be energy self-sufficient, but also to feed the remaining electricity into the grid. This is a new requirement for the construction industry.
The use of environmentally friendly building materials has injected “fresh blood” into the construction industry. Environmental protection building materials not only solve the environmental pollution problem that people generally pay attention to, but also realize the rational use and recycling of resources, making the building more perfect in design and construction.
Environmental protection building is based on environmental protection materials. By vigorously promoting the use of environmental protection building materials, using modern high-tech tools for design and construction, using pollution-free production technology, sustainable development of buildings will gradually become a reality. Green building is in line with the concept of sustainable development, the product of harmonious coexistence between human and nature, and the symbol of human civilization. We should consciously protect the living environment, create a good living environment and create a harmonious green home.
