Description
Technical field
The present invention relates to discarded construction material process fields, and in particular to a kind of light bone prepared using discarded clay brick
Expect concrete.
Technical background
According to reports, China produced 20,000,000,000 m in total in past 50 years3The clay brick of left and right, and these clay bricks
It will be discarded with removal, and account for about the 30%~50% of total amount of construction waste according to estimation.Meanwhile with domestic infrastructure
Development, sand and stone resources are also increasingly deficienter.How building castoff is being solved with finding a stationary point in resource recycling,
It is current urgent problem.
It can alleviate the sand and stone resources gradually political affairs of the situation of scarcity and national energy-saving emission reduction there is presently no a kind of
Plan, and not only there is the effect of light thermal-insulation, the lightweight aggregate coagulation of clay brick preparation is discarded in the utilization for also having both sound absorption effect
Soil.
Invention content
The present invention be exactly in view of the above-mentioned problems, provide it is a kind of can alleviate sand and stone resources gradually deficient situation and
The policy of national energy-saving emission reduction, and not only there is the effect of light thermal-insulation, clay brick is discarded in the utilization for also having both sound absorption effect
The lightweight aggregate concrete of preparation.
In order to achieve the above objectives, the present invention uses following technical scheme.
The lightweight aggregate concrete prepared using discarded clay brick, including major ingredient, auxiliary material, it is characterised in that major ingredient includes clay
Brick coarse aggregate, clay brick fine aggregate, auxiliary material include cement, flyash, silicon powder, water-reducing agent, water, and each component mass percent expires
Foot is claimed below：Clay brick coarse aggregate 35%~45%, clay brick fine aggregate 25%~35%, cement 15%~25%, flyash 1%~
2%th, silicon powder 0.3%~0.8%, water-reducing agent 0.5%~2%, water 5%~10%.The clay brick coarse aggregate is 10~20mm by grain size
Clay brick aggregate and grain size be 4.75~10mm clay brick aggregate in mass ratio 4:1 ratio is uniformly mixed, and makes gained grain
Diameter grading meets the requirement of 5~20mm continuous gradings.The clay brick fine aggregate grain size is 0.5~4.75mm.The cement is preferred
Density is the portland cement of 3.0g/cm3.The flyash preferred density is the Class F fly ash of 2.4g/cm3.The diminishing
Agent needs to meet：Solid content is 10.55%, water-reducing rate 26%.
The present invention also provides a kind of methods for preparing lightweight aggregate concrete using discarded clay brick, include the following steps：First,
Aggregate crushes, discarded clay brick is crushed by movable crusher, sieves, clean, dry after obtain particle size range point
It is not：10~20mm, 4.75~10mm, 0.5~4.75mm regeneration clay brick aggregate；2nd, prepared by major ingredient, will be in step 1
Particle size range for 10~20mm and 4.75~10mm regeneration clay brick aggregate by certain mass than mixing as the thick bone of clay brick
Expect it is spare, particle size range be 0.5~4.75mm regeneration clay brick aggregate it is spare as clay brick fine aggregate；3rd, it feeds intake, it will be glutinous
Cob brick coarse aggregate, clay brick fine aggregate, cement, flyash, silicon powder after metering system is weighed by bucket elevator are put into and stirred successively
It mixes and is stirred in advance in machine 60 seconds or more；4th, spice adds in a certain amount of water in the powder stirred in advance excessively in step 3 and subtracts
Aqua is stirred for 120 seconds or more.
The present invention can not only solve to build to give up using discarded clay brick as regeneration lightweight aggregate to prepare lightweight aggregate concrete
The problem of gurry processing, and the gradual deficient situation of sand and stone resources can also be alleviated, and prepared as aggregate by broken common brick
Lightweight aggregate concrete there is the effect of light thermal-insulation, meet the policy of national energy-saving emission reduction.Meanwhile matched using of the present invention
The lightweight aggregate concrete just produced has good mechanical performance, while anti-freezing property meets existing professional standard JGJ 51-2002
《Lightweight aggregate concrete technology regulation》Regulation.
