Nowadays, the actual service life of buildings in our country is generally 25 to 30 years. Some newly built buildings have also been demolished, which is also called the phenomenon of "building life". Not only is it causing serious waste of resources, but also polluting the environment, not only is the city dusty and dusty all the day, but also more and more cities are being hitched again and again. And more and more cities are littered with construction rubbish, The more arable land has to be "transformed" into a landfill. In fact, the construction waste is misplaced resources, it is transformed into building materials is the embodiment of circular economy.
Henan Shengtian Environmental Renewable Resources Co., Ltd. to introduce SBM mine research and development production YPS building rubbish crushing plant launched
construction waste crusher project in Zhengzhou, and several well-known domestic universities to set up Henan's first recycling of construction waste Use research demonstration base. The construction waste crusher processing capacity of 2 million tons / year. Recycled aggregate, drywall retaining wall, pavement brick, grass planting brick, permeable brick, hydraulic brick, tile and other seven major categories of products processed by the construction waste crushing station include recycled fine aggregate, medium aggregate, Coarse aggregate, small standard brick, guide blind brick, square brick, porous wall brick, single row hole wall brick, maple leaf brick, Spanish brick, Dutch brick, hollow brick, semicircular curb, Stone, single-hole grass planting brick, well-shaped planting grass brick, single-hole interlocking hydraulic brick, toothed planting brick, four hole grass planting brick, grass planting brick and so on more than 20 varieties.
Shenzhen Nankai Science and Technology Co., Ltd. adopts SBM mine construction rubble crushing and brick making equipment. The construction rubbish can be made into 15 types of green regenerated building materials products such as recycled aggregate, solid brick, hollow brick, colored Dutch brick, permeable brick and grass planting brick at the site Products will be fully used for the South Division, deep new campus construction. At present, the use of construction waste to produce new building materials has been widely used in a number of construction projects, so that enterprises have achieved good economic and ecological benefits. The new building materials produced by the construction waste treatment equipment are superior to other building materials products in terms of quality and hardness. No harmful gases are generated in the whole production process and the zero emission of local construction waste is basically achieved. It is reported that the South Branch of the building waste disposal methods used on-site, saving about 6 hectares of land resources; according to comprehensive utilization of construction waste recycling utilization of 90% total, natural sand and raw materials can reduce the consumption of 600,000 cubic meters; can save construction Disposal of landfills and landfill disposal costs more than 4000 million; to achieve the output value of more than 6,000 yuan.
After testing, construction waste made of bricks, construction waste content generally up to 70% -80%, some of the models made entirely of construction waste. The fine aggregate and grout made of such ordinary cement brick ratio, compressive strength exceeds the national standard, up to 30 MPa, much higher than the average solid brick, sintered brick. The construction waste disposal equipment can solve the contradiction problem of urban construction waste and turn waste into treasure at the same time. The construction waste can be recycled and reused, which is in line with the state's policy of developing circular economy and protecting the environment. The use of advanced dust removal equipment, noise, dust emissions fully meet the requirements of the EIA. The state encourages the comprehensive utilization of construction waste and encourages construction units and construction units to give priority to the comprehensive utilization of construction waste products.
