Background

The building is an important place for activities and living of people, along with social development and urban planning change, many buildings need to be overturned for reconstruction or renovation due to old or low land utilization rate and other reasons, and building waste can be generated no matter reconstruction or renovation, particularly building solid waste is taken as a main material, and building solid waste is called building solid waste for short.

The building solid waste mainly contains concrete, bricks, wood, metal, glass and other substances, wherein due to the wide application of the concrete, the concrete material accounts for a relatively large proportion in the building solid waste, and no matter the building solid waste is pushed down for reconstruction or renovated, the generated building solid waste is damaged and mixed together, and the building solid waste and various substances are randomly mixed and mixed to form the building solid waste, so that the building solid waste is difficult to directly reuse.

Therefore, the recycling of the building solid waste is imperative, and in the recycling of the building solid waste, metal materials and large pieces of wood which are easy to sort are usually picked out to be recycled independently, and the rest of mixed materials which are difficult to sort are damaged to be used as fillers or aggregates, but due to the fact that the materials are mixed and have different performances, the performance is unstable when the mixed materials are used as the fillers or the aggregates, and in order to guarantee the engineering quality, the mixing amount is usually less, so that the consumption of the building solid waste is slow, the pollution of the building solid waste to the environment is difficult to relieve, and therefore, a space is provided for improvement.

Experiment 1

And (3) detecting the 7d and 28d compressive strengths of concrete samples prepared from the concrete mixture of each application example and the comparative example according to the standard GB/T50081-2016 of the test method for mechanical properties of common concrete.

The assay data for experiment 1 is detailed in table 2.

TABLE 2

According to the comparison of the data of the application examples 1-8 and the comparison example 1 in the table 2, when the nonmetallic waste is heated at 760-780 ℃, the compressive strength of the prepared concrete material is equivalent to that of the concrete material prepared by only using the new Portland cement when the doping amount of the obtained doping gel material is 30% of the mass of the cement, and no obvious negative effect is caused.

According to the data of the application examples 11 and 12 and the application example 5 in the table 2, when the heating temperature is too high or too low, the compressive strength of the concrete material is obviously reduced under the condition that the mixing amount of the mixable gel material is the same.

Therefore, only within a specific heating range, it is possible to separate cement waste and aggregate among the non-metal waste well and to allow the cement waste to be rehydrated for reuse.

According to the comparison of the data of the application examples 7 and 8 and the data of the application example 5 in the table 2, the addition amount of the auxiliary agent is increased within a certain range, and the compression strength of the prepared concrete material is slightly improved.

According to the comparison of the data of the application examples 13-15 and the data of the application example 5 in the table 2, the compressive strength of the prepared concrete material is reduced to a certain extent without adding any auxiliary agent or only by adding the hydroxymethyl cellulose or the cyclopentasiloxane under the condition of the same doping amount, so that the hydration reaction degree can be increased by the hydroxymethyl cellulose, the cyclopentasiloxane can reduce the condition that an interface is formed between a colloid formed by new cement and a colloid formed by the incorporatable gel material, and the compressive strength of the concrete material is increased by the cooperation of the hydroxymethyl cellulose and the cyclopentasiloxane, so that the influence of the reduction of the compressive performance of the concrete material caused by the incorporation of the incorporatable gel material is filled, and the doping amount of the incorporatable gel material is increased.

According to the comparison of the data of the application examples 9 and 10 and the data of the application example 5 in the table 2, the mixing amount of the gel material which can be mixed is increased after the glass powder is annealed, and the compressive strength of the prepared concrete material is not obviously reduced, so that the compressive strength of the concrete is improved by paying attention to the fact that the glass powder is annealed to form the toughened glass powder, and the influence of the increase of the mixing amount of the gel material which can be mixed on the concrete material is reduced.

As can be seen from the comparison of the data in Table 2 between application example 16 and comparative example 1, the mixing amount of the sand and stone wastes prepared in example 5 at 50% does not have a significant negative effect on the compression resistance of the concrete material produced. The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
