Crushing process of tunnel slag sand making machine
A large amount of slag is inevitably generated during tunnel construction. To deal with these slag, a large amount of…
Construction waste products mainly include recycled aggregate, ready-mixed mortar and recycled concrete. In the production of these three materials, a complete set of construction waste treatment production line equipment is required. Generally speaking, these devices mainly include tire-type mobile crushing station, construction waste shredders, etc., which can regenerate construction waste into road structural materials, energy-saving thermal insulation wall materials, sidewalk permeable materials, and composite materials for municipal facilities.
The three main recycled products of construction waste are widely used, and their use value is fully reflected. Recycled aggregate market: The development of urban construction has entered a period of rapid development. Large-scale production lines have been newly built in the cement industry, and projects such as highways, railways, and water conservancy projects have increased, and the supply of commercial concrete is in short supply. Aggregate as a raw material maintains a good supply and demand relationship. These are inseparable from the assistance of construction waste crushers.
Ready Mixed Mortar Market:
Recycled aggregate produces ready-mixed mortar, which is not much different from traditional mortar in terms of production equipment and labor. Since the price of recycled aggregate is lower than that of natural mortar products, and the transportation distance will be greatly shortened, the strength level of the mortar is not high, and the amount of cement in the unilateral cement and the amount of additives have slight changes, but the difference is not very big. Since recycled aggregate accounts for more than 50% of the total weight of mortar, income tax can be reduced or exempted according to the comprehensive utilization policy of resources. Therefore, the profit margin per ton of ready-mixed mortar products produced with recycled aggregates of the same strength grade is much larger than that of general ready-mixed mortar plants.
Recycled Concrete Products Market:
Recycled products mainly include: concrete blocks and concrete slabs. Waste concrete and bricks from construction waste can be used to make recycled bricks and blocks. The cementitious material for non-sintered products shall be cement, and shall be mixed with appropriate recycled coarse aggregate, fine aggregate and powder.
The strength of concrete bricks made by construction waste crusher is 20% higher than the national standard. Can be made into pavement and wall tiles. The price of construction waste bricks is significantly lower than that of clay bricks, which effectively saves land resources.
