Embodiment 1

[0020] Take stone powder sludge with a water content of 60%, preliminarily settle in the sedimentation tank, release the water on the surface of the sedimentation tank, and filter the water for later use. Excavate the stone powder sludge in the sedimentation tank, the water content of which is 50%, and apply mechanical dehydration to the stone powder sludge to reduce the water content of the stone powder sludge to 5%, and the water obtained by mechanical dehydration is filtered for use. This stone powder sludge 60kg, label is 9.4kg of cement 42.5R, sand 6kg, length is 0.1kg of fiber for construction engineering of 2cm, particle diameter is less than 20kg of stone material waste slag of 1cm, mortar king (national standard is called: masonry mortar increased Plasticizer) 0.5kg, SPP-100 high-performance reinforcing agent 1kg, quick-setting agent 3kg mix, then add appropriate amount of water, stir and mix evenly, add to 3m 3 In the mold, extrusion vibration vacuumizes, demoulding ...

Embodiment 2

[0023] Take stone powder sludge with a water content of 65%, preliminarily settle in the sedimentation tank, release the water on the surface of the sedimentation tank, and filter the water for later use. Excavate the stone powder sludge in the sedimentation tank, its water content is 30%, and apply mechanical dehydration to the stone powder sludge to reduce the water content of the stone powder sludge to 10%, and the water obtained by mechanical dehydration is filtered for later use. This stone powder sludge 62kg, the cement 8.4kg that label is 42.5R, sand 5kg, the fiber 0.1kg that length is 2cm, the stone waste slag 20kg that particle diameter is less than 1cm, mortar king (national standard is called: masonry mortar increases Plasticizer) 0.5kg, SPP-100 high-performance reinforcing agent 1kg, quick-setting agent 3kg mix, then add appropriate amount of water, stir and mix evenly, add to 3m 3 In the mold, extrusion vibration vacuumizes, demoulding after curing, and then harde...

Embodiment 3

[0026] Take stone powder sludge with a water content of 70%, preliminarily settle in the sedimentation tank, release the water on the surface of the sedimentation tank, and filter the water for later use. Excavate the stone powder sludge in the sedimentation tank, its water content is 45%, and apply mechanical dehydration to the stone powder sludge to reduce the water content of the stone powder sludge to 20%, and the water obtained by mechanical dehydration is filtered for later use. This stone powder sludge 50kg, label is 28kg of cement of 42.5R, ZL205 modifier 1kg, length is 0.1kg of fiber for construction engineering of 2cm, stone material waste slag 14.4g less than 1cm in particle diameter, mortar king (the national standard is called: masonry) Mortar plasticizer) 0.5kg, SPP-100 high-performance reinforcing agent 1kg, quick-setting agent 5kg, add appropriate amount of water, stir evenly, add to a 3×1.5m mold, squeeze and vibrate to vacuum, Release the mold after curing, t...

Abstract

The invention discloses a concrete product prepared from stone sludge waste residues and a preparation method thereof. The concrete product is prepared from the following raw materials in percentage by mass: 50 to 62.5 percent of fine aggregate sludge with moisture content of 5 to 20 percent, 8 to 28 percent of cement, 0.1 to 0.3 percent of fibers for constructional engineering, 13 to 20 percent of stone waste residues with grain diameter of less than 1 centimeter, 0.3 to 0.7 percent of masonry mortar plasticizer, 0.5 to 2 percent of intensifier, 3 to 5 percent of accelerating agent and 5 to 7 percent of sand or 0.5 to 1.5 percent of modifier. By the method, the concrete product with the economic benefit can be prepared from the stone sludge waste residues, the problem of pollution discharging in industry of stone sludge and residues is solved effectively, the aim of recycling wastes is fulfilled, precious occupied earth resources for stacking the stone sludge and the residues are reduced and even eliminated and resources and funds are saved.

Description

Technical field: [0001] The invention relates to a concrete product and a preparation method thereof, in particular to a concrete product prepared from stone sludge and a preparation method thereof. Background technique: [0002] The stone industry in Yunfu City has a development history of more than 200 years. It is currently the largest stone distribution center in the country, and it is also a characteristic industry and a pillar industry in Yunfu City. There are nearly 5,000 stone production and processing enterprises, and the sludge and waste generated by stone production and processing reach 3 million tons every year. [0003] The sludge and waste residue containing stone powder can neither be directly landfilled, which will cause secondary pollution, nor can it be used as a substrate for agriculture. The current treatment method is to free up part of the land specially for stacking these sludge and waste residues. But this kind of treatment is only a short-term beha...
