preparation example Construction

[0029] Such as figure 1 Shown is the preparation method of the above-mentioned green polymer concrete regenerated brick provided by the embodiment of the present invention, comprising the following steps:

[0030] Step S11: Mix the residual sludge, water, water glass and sodium hydroxide, and stir in a stirrer with a rotating speed of 200r / min-300r / min to form a slurry of sludge. In this step, 200-400 parts of residual sludge (mass parts, the same below), 50-150 parts of water, 200-280 parts of water glass and 100-140 parts of sodium hydroxide.

[0031] Specifically, the sand content of the residue sludge in this embodiment is 25%-60%, which can be obtained from new construction, reconstruction, expansion and demolition of various buildings, structures, roads, pipe networks, etc., and the process of residential decoration and house decoration. Spoils, waste materials and other wastes generated. Moreover, the above-mentioned residual sludge can be obtained by blending spoils,...

Embodiment 1

[0040] Prepare the green polymer concrete regenerated brick raw material (×10kg) according to the following proportions by weight: 300 parts of residual sludge, 100 parts of slag powder, 100 parts of cement, 200 parts of water glass, 100 parts of sodium hydroxide, recycled fine aggregate 350 parts, 500 parts of recycled coarse aggregate, 200 parts of water, 20 parts of admixture.

[0041]Mix 300 parts of residual sludge, 100 parts of water, 200 parts of water glass, and 100 parts of sodium hydroxide, and stir in a stirrer with a rotating speed of 240 r / min to form a slurry of sludge. Add 500 parts of recycled coarse aggregate, 350 parts of recycled fine aggregate, 100 parts of cement, 100 parts of slag powder, 700 parts of dregs slurry, and 100 parts of water into the concrete mixer and mix evenly. The mud can be cleaned with water and poured into the mixer. The stirring speed of the mixer is 60r / min, and the stirring time is 60s. Lay a silicone film with a specific pattern ...

Embodiment 2

[0043] Prepare the green polymer concrete regenerated brick raw material (×10kg) according to the following proportions by weight: 250 parts of residual sludge, 130 parts of slag powder, 80 parts of cement, 200 parts of water glass, 100 parts of sodium hydroxide, recycled fine aggregate 380 parts, 540 parts of recycled coarse aggregate, 185 parts of water, and 17 parts of admixture.

[0044] Mix 250 parts of residual sludge, 90 parts of water, 200 parts of water glass, and 100 parts of sodium hydroxide, and stir in a stirrer with a rotational speed of 240 r / min to form a slurry of sludge. Add 540 parts of recycled coarse aggregate, 380 parts of recycled fine aggregate, 130 parts of cement, 130 parts of slag powder, 640 parts of dregs slurry, and 95 parts of water into the concrete mixer and mix evenly. The mud is cleaned with water and poured into the mixer. The stirring speed of the mixer is 60r / min, and the stirring time is 80s. Lay a silicone film with a specific pattern ...

Abstract

The embodiment of the invention provides a green polymer concrete recycled brick and a preparation method thereof. The green polymer concrete recycled brick is prepared from the following raw materials in parts by mass: 200-400 parts of refuse and clay residue, 100-150 parts of slag powder, 50-200 parts of cement, 200-280 parts of water glass, 100-140 parts of sodium hydroxide, 200-400 parts of recycled fine aggregate, 400-600 parts of recycled coarse aggregate, 160-220 parts of water and 10-30 parts of an additive. According to the embodiment of the invention, the refuse and clay residue generated by engineering construction and the industrial waste slag powder are directly used for producing the green polymer concrete recycled brick, the construction waste such as the refuse and clay residue and the recycled coarse and fine aggregates can be directly utilized, the production cost is reduced, the industrial waste slag powder is utilized, the phenomenon that the construction waste encircles a city is avoided, and the green polymer concrete recycled brick has good environmental benefits, economic benefits and social benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a green polymer concrete regenerated brick and a preparation method thereof. Background technique [0002] "Remaining mud and slag" refers to the spoils, waste materials and other wastes produced by construction units, construction units, new construction, reconstruction, expansion and demolition of various buildings, structures, roads, pipe networks, etc., as well as residents' decoration and house decoration process. . With the large-scale construction of the city, the construction projects such as high-rise buildings and rail transit have increased sharply, and the residual mud and slag generated have also greatly increased. The discarded sludge and slag have seriously affected the surrounding environment, causing air pollution, water pollution, and affecting the appearance of the city. At present, the main measures adopted in our country are site backfilling, mountain land...
