[0002] At present, the disposal of waste such as masonry, rubble, concrete beams and columns abandoned by urban construction and demolition has become a difficult problem in urban construction. It not only requires a lot of manpower and material resources to transfer these wastes, but also has disadvantages such as land occupation and environmental pollution.
The applicant's previous application "fly ash four-free brick" (application number 02103621.7) discloses a method for making industrial waste fly ash into high-strength four-free brick, which provides an effective and feasible method for the treatment of industrial waste However, there is no literature report on making urban construction and demolition waste into building materials

Embodiment 1
[0029] 1. Stir the mixture consisting of 80% urban construction demolition waste and 20% cement first;
[0030] 2. Evenly mix and react additive No. 1 liquid and No. 2 liquid at a ratio of 1.5:1 to form a silica gel solution for later use;
[0031] 3. Add the silica gelslurry into the mixture according to the weight ratio of the silica gelslurry and the mixture at 14:100, and stir for 5 minutes to make it uniform;
[0032] 4. Sent to pressing equipment for pressing, forming and stacking;
[0033] 5. It can leave the factory after two times of water curing.
[0034] The strength is MU15, which can be used as load-bearing bricks.
Embodiment 2
[0036] 1. Stir the mixture consisting of 90% urban construction demolition waste and 10% cement first;
[0037] 2. Add 7.5 parts of No. 1 liquid to 100 parts of the mixture. The components of No. 1 liquid and the percentage of bulk density are 20% sodiumsilicate and 80% water, and mix well;
[0038] 3. Then add 5 parts of No. 2 liquid according to 100 parts of the mixture. The components of No. 2 liquid and the percentage of bulk density are 10% of sulfuric acid and 90% of water, and mix well;
[0039] 4. Sent to pressing equipment for pressing, forming and stacking;
[0040] 5. It can leave the factory after two times of water curing.
[0041] The strength is MU10, which can be used as non-load-bearing bricks.
Embodiment 3
[0043] 1. Stir the mixture consisting of 90% urban construction demolition waste and 10% lime evenly;
[0044] 2. Add 6 parts of No. 1 liquid to 100 parts of the mixture. The components and volumetric weight percentages of No. 1 liquid are 20% sodiumsilicate and 80% water;
[0045] 3. Then add 4 parts of No. 2 liquid according to 100 parts of the mixture. The components and volumetric percentages of No. 2 liquid are 10% of sulfuric acid and 90% of water;
[0046] 4. Sent to pressing equipment for pressing, forming and stacking;
[0047] 5. It can leave the factory after two times of water curing.
[0048] The strength is MU10, which can be used as non-load-bearing bricks.

Abstract
The present invention relates to building material technology, and is especially one kind of high strength rubblebrick. The production process of the high strength rubblebrick includes mixing crushed and ground building rubbish and hard material in certain ratio to form mixture; adding No. 1 solution or water solution of sodiumsilicate in concentration of 1-20 wt% in 4.8-10.8 weight portions to the mixture of 100 weight portions; adding No. 2 solution or water solution of sulfuric acid in concentration of 1-15 wt%; pressing and stacking; and curing including twice water spraying. The present invention realizes the circular utilization of building material, and the product of the present invention his low cost.
