Technical Field
The invention belongs to the technical field of solid waste resource utilization and the application field of building materials, and particularly relates to a method for applying waste rock wool balls to concrete.
Background
Along with the continuous development of rock wool industry, the rock wool waste material is more and more, and rock wool is as insulation material, and the quantity is big, abandons promptly after once only generally, if can't carry out effective processing, will certainly produce negative effects to the environment. Rockwool waste is made up of two parts, one resulting from the process of building demolition and the other from the process of building construction.
The waste rock wool is difficult to degrade, pollutes the environment and has the harm of causing cancer to people. At present most rock wool waste material is all dumped and is buried, and this part waste residue waste material quantity is few then thousands tons many then tens of thousands tons every year, dumps and buries not only extravagant manpower, power of transportation, faces very big environmental protection pressure moreover. How to find a reasonable recycling mode for rock wool waste materials and ensure the healthy and durable development of the rock wool industry is a problem to be urgently solved by the industry at present.
At present, many researchers are studying the comprehensive utilization technology of waste rock wool, for example, waste rock wool is used as a mineral admixture to improve the comprehensive performance of a cement-based cementing material, but the addition amount of waste rock wool fiber is small and only accounts for 2% (by volume). The waste rock wool is modified and applied to sewage treatment, although the treatment effect is good, new solid waste is finally generated, and the problem is not solved fundamentally.

The waste rock wool is made into the pellets, three disposal modes are adopted, the rock wool amount consumed by each mode is different, and the pellets with different strength and water absorption are obtained; the high-strength concrete has high requirements on the strength, the grain diameter and the mixing proportion of the pellets, so the pellet A consolidated by the organic-inorganic compound cementing material can be used in the high-strength concrete; the lightweight aggregate concrete has low requirements on the strength and the water absorption of the pellets, and the pellets C solidified by the clay can be used in the lightweight aggregate concrete; the strength of the common concrete is close to the middle of the former two types, so the inorganic cementing material and the solidified small balls B can be used in the common concrete.
The existing waste rock wool is troublesome to treat, most of the waste rock wool is discarded or stacked, the rock wool is large in size and light in weight, the occupied area is large, the long-term stacking can pollute the environment, the waste rock wool is made into rock wool fibers or rock wool powder to be added into a formula of concrete, the adding amount of the rock wool is small, and the peaceability of the rock wool in mortar is poor, so that the rock wool is easy to float on the surface. According to the invention, waste rock wool and gel material or clay are made into pellets and then are applied to concrete instead of a part of coarse aggregate, so that the mixing amount of the rock wool can be increased on one hand, and the workability of the rock wool in the concrete can be improved on the other hand. The invention provides a new method for treating rock wool solid waste. By adopting the method, the waste rock wool can be treated to the maximum extent, 25-100 kg of waste rock wool can be comprehensively treated by each concrete, and the treatment capacity of the waste rock wool is improved.
