Description
Technical field
The present invention relates to a kind of paving bricks prepared using discarded clay brick and preparation method thereof, belong to construction material neck
Domain.
Background technology
With China's economic development and the quickening of ur- banization speed, large quantities of old buildings, building waste are all removed every year
Increased, wherein clay brick accounts for sizable ratio, and huge pressure is brought to environment and land resource.According to statistics, I
State discards about 52,000,000 tons of the quantum of output of clay brick every year, therefore the efficient utilization of clay brick can improve construction refuse resource
Integral level, effectively save energy resources reduce the destruction to limited arable land, reduce the pressure to environment.
The utilization for discarding clay brick is concentrated at present and prepares recycled aggregate, regeneration filler etc., overall regeneration is horizontal
Low, the product actual use of regeneration is range-restricted big.For example, patent is " to discard clay brick as the regeneration for substituting coarse aggregate
Concrete and preparation method thereof（CN201510487381.5）" and the patent " regeneration of the discarded clay brick of use and discarded concrete
Aggregate concrete and preparation method thereof（CN201510487349.7）" report by discarded clay brick be made aggregate re-use,
But the adding proportion 10%~30% of discarded clay brick, and as the raising of additive amount, water absorption rate gradually increase, affect coagulation
The intensity of soil.Patent " a kind of to utilize alkali-excited cement of discarded clay brick powder and preparation method thereof "（CN 105399353 A）Report
Clay brick grinds using alkali-activated carbonatite, are prepared geopolymer by road.This method needs to add high-calcium fly ass, and one
Maintenance obtains, while belong to clinker-free cement under fixed condition, part of cement can only be replaced to use in a certain range.
Invention content
The purpose of the present invention is in view of the deficienciess of the prior art, in order to realize efficiently using for discarded clay brick, make
Standby high-performance paving brick, proposes a kind of paving brick prepared using discarded clay brick and preparation method thereof, and discarded clay brick can be with
Primary full utilization, utilization rate 100%, and the paving brick prepared is had excellent performance.
For this purpose, the present invention using technical solution it is as follows, using discarded clay brick prepare paving brick, it is raw materials used by weight
Part is counted：Discarded 100 parts of clay brick, 10-20 parts of cement, 0.3-0.5 parts of reinforcing agent, 0.5-1.0 parts of surface modifier, water
10-15 parts.
The reinforcing agent is any one or a few of acrylic acid ester emulsion, styrene-butadiene emulsion, styrene-acrylic emulsion or silicone acrylic emulsion,
Solid content is 45-55%.
The surface modifier is cationic surfactant：Diethanol amine, triethanolamine or lauric acid amide of ethanol
Any one or a few.
The cement is scenery with hills and waters P × O425 portland cements.
Preparation method step of the present invention is as follows：
（1）Discarded clay brick is crushed into shaping sub-sieve, discarded clay brick Powder Particle Size is distributed as：＜ 0.15 mm, 15%-20%；
0.15mm-1.5mm, 50%-65%；4.75 mm-9.5 mm, 20%-30%；The discarded clay brick powder of size distribution ＜ 0.15mm
Middle addition surface modifier, is uniformly mixed；
（2）Cement, reinforcing agent, water are added in discarded clay brick to be mixed evenly；
（3）In 50-60 MPa forming under the pressure, demoulding, standard curing 28 days obtain tile product of paving the way.
The beneficial effects of the invention are as follows：
（1）Discarded additive amount of the clay brick in the paving brick of preparation is in 80-85%, and the primary profit completely of discarded clay brick
With utilization rate 100% does not generate secondary byproduct, the useless environmental protection of profit.
（2）Cationic surfactant and addition lotion reinforcing agent are added in brick powder, it can be with electronegative emulsion particle phase
Mutually absorption, so as to change the electrical of lotion surface, raising and the combination on broken clay brick surface.Cation and broken brick powder simultaneously
When being used together, the viscosity of emulsion particle can be reduced, so as to inhibit the accumulation of emulsion particle, improves the property that paving brick is made
Energy.
（3）Prepared by the present invention paves the way tile product in unit weight 1900-2000 kgmm-3, the performance indicators such as intensity are superior to
National standard.
