Description
Technical field
The present invention relates to discarded construction material process fields, and in particular to a kind of to utilize the permeable of discarded clay brick preparation
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 pervious concrete of clay brick preparation is discarded in the utilization for also having both sound absorption effect.
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 pervious concrete of preparation.
In order to achieve the above objectives, the present invention uses following technical scheme.
The pervious 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, silicon powder, additive, water, and each component mass percent meets following want
It asks：It is clay brick coarse aggregate 65%~80%, clay brick fine aggregate 2%~5%, cement 15%~25%, silicon powder 0.3%~0.8%, additional
Agent 2.5%~2.0%, water 4%~10%.The clay brick coarse aggregate size is 4.75~10mm.The clay brick fine aggregate grain size
For 0.5~4.75mm.The cement preferred density is the portland cement of 3.0g/cm3.The additive needs to meet：Solid content
It is 13.55%, water-reducing rate 26%.
The present invention also provides a kind of methods for preparing pervious concrete using discarded clay brick, include the following steps：First, bone
Material is broken, discarded clay brick is crushed by movable crusher, sieves, clean, dry after obtain particle size range difference
For：The regeneration clay brick aggregate of 4.75~10mm, 0.5~4.75mm, wherein, grain size is thick as clay brick for 4.75~10mm
Aggregate, grain size are 0.5~4.75mm as clay brick fine aggregate；2nd, it feeds intake, by clay brick coarse aggregate, clay brick fine aggregate, water
Mud, silicon powder after metering system is weighed by bucket elevator are put into and are stirred in advance in blender 60 seconds or more successively；3rd, spice, in step
A certain amount of water and additive are added in the powder stirred in advance excessively in rapid two, is stirred for 120 seconds or more.
The present invention can not only solve construction waste using discarded clay brick as regeneration lightweight aggregate to prepare pervious concrete
The problem of object processing, and the gradual deficient situation of sand and stone resources can also be alleviated, and prepared by crushing common brick as aggregate
Pervious concrete has the effect of light thermal-insulation, meets the policy of national energy-saving emission reduction.Meanwhile it is given birth to using formula of the present invention
The pervious concrete of production has good mechanical performance, while the intensity of pervious concrete meets existing country's mark GB/T 50107
《Standard for inspection and assessment of strength of concrete》Regulation, coefficient of permeability meets existing professional standard CJJ/T 135《Permeable cement coagulation
Soil surface technical regulation》Regulation.
