Specific implementation mode
Embodiment
With jaw crusher by discarded paving brick, as shown in Figure 1, broken, being then sieved into grain size with sieve is
Two kinds of specifications of 0.35~4.75mm and 4.75~32mm are used as thick, the fine aggregate of regeneration concrete.Object is carried out to above-mentioned aggregate
Performance test is managed, it is as a result as follows：
Table 1 discards paving brick aggregate physical property
The above items aggregate physical performance index unit is kg/m3.All Sand for Concrete stone all meets common mixed
The requirement of solidifying native sand, stone quality and test method standard.
Regeneration concrete charge ratio is designed according to test result, i.e. their mass ratio is：Gel rubber material：Regenerate thin bone
Material：Regenerated coarse aggregate：Water：Additional water：Fiber=1:1.66:2.5:0.5-0.6:0.1:0.003.Table specific as follows：
2 charge ratio (kg/m of table3)
Wherein, gel rubber material is the mixture of cement and flyash, and cement is 42.5R Portland cements, polypropylene
Fiber is as shown in Fig. 2, physical data is as follows：
3 polypropylene fibre property of table
Under room temperature, various raw materials are mixed with 30L concrete mixers, can be cast in model after mixing,
It can become prefabricated test specimen through maintenance.
The size and curing condition of the making test specimen of this experiment are references《Normal concrete mechanical property test side
Method standard》(GB/T50081-2002) requirement in, test specimen making make according to standard test mode, die trial inner surface brush releasing agent.
Test specimen is all made of standard curing method, is counted from stirring plus water time, and curing age is 28 days, and there are plastics on surface in maintenance processes
Film blanket, conserved in laboratory test specimen is numbered again within 1 to 2 day, form removal.The surface of test specimen keeps moist in maintenance, supports
Water test block surface is not poured into directly during shield.
The every of test block is detected see following table：
Table 4 detects specimen Design list
Table 5 is using discarded paving brick as the concrete dense angle value of aggregate
The density of the density ratio normal concrete of studied concrete herein as can be seen from the above results
(2500kg/m3) want low, have the characteristics that lightweight.
6 Compressive Strength of Recycled Concrete test data of table
As can be seen from Table 6 in water/gel rubber material ratio is respectively 0.5 (A groups), 0.55 (B groups), 0.6 (C groups), cube
Higher body compression strength value is A groups, the cubic compressive strength value (30MPa) of normal concrete is above, wherein highest
It is that A3 group 33.9MPa improve 13% compared with normal concrete cubic compressive strength (30MPa).
7 shaft center compression resistant test data of table
It can be seen that from table：In discarded paving brick regeneration concrete test block shaft center compression resistant experiment, being averaged for fiber is mixed
Stress highest is 23.2MPa, and discarded brick recycled aggregate concrete of paving the way has met normality condition.The test specimen plane of disruption is in X
Type, the plane of disruption is more uniform, and for Surface layer's concrete without large area obscission, globality is preferable after experiment.
Table 8 is using discarded paving brick as the modulus of elasticity of concrete test value of aggregate
It can be seen that from table：Using discarded paving brick as the elasticity modulus of the regeneration concrete of raw material, more general C30 coagulations
Soil wants lower.The reason is that because：(1) recycled aggregate itself intensity being used in regeneration concrete is relatively low, makes regeneration coagulation
The ability that soil bears deformation is smaller to affect the size of elasticity modulus；(2) porosity of raw material is higher, it is prone to non-ballistic
Property deformation.
According to scholar Mellmann through overtesting and analysis, it is proposed that concrete when recycled coarse aggregate contents are 100%
Formula E is closed in elasticity modulus and the conversion of its compression strengthc=378fcu+8242
In formula：Ec--- elasticity modulus MPa fcu--- cubic compressive strength MPa
It is computed：Ec=21056MPa, the calculated value of the formula is close with obtained numerical value is tested, therefore with discarded
Paving brick, which is the elasticity modulus of the regeneration concrete of aggregate, has certain practicability and reliability.
9 flexural strength test data of table
It can be seen that from table：Using discarded paving brick as the flexural strength of the regeneration concrete of raw material with vertical load by
It is cumulative plus, test specimen bottom surface starts the minute crack for occurring small, the position in crack be located at two applied loads it
Between.Continue to increase load, crack is vertically extending to be then broken off through test specimen.In the regeneration concrete of three kinds of match ratios, mix
After entering polypropylene fibre, flexural strength is that 3.1MPa raisings are more apparent.
10 splitting tensile test data of table
It can be seen that from table：Using discard paving brick as the tensile splitting strength value of the regeneration concrete of aggregate it is whole compared with
It is low, after mixing polypropylene, slightly improved compared to other two groups.Such regeneration concrete tensile splitting strength value it is lower the reason is that
Regenerated coarse aggregate and cementitious material cohesive force are relatively small, and cohesive effect is not strong enough, are easily sent out in concrete under tension
There is small minute crack in raw cracking, and recycled aggregate inherently has some defects (such as crack etc.) so that its test block
Destruction is easy tod produce when reeling.Although the tensile splitting strength value of such regeneration concrete is relatively low, concrete is led in the structure
If playing resistance to compression, and such Compressive Strength of Recycled Concrete is higher, therefore there is higher practical value.
In conclusion to that can be drawn a conclusion as the testing result of the regeneration concrete of aggregate using discarded paving brick：
1, by test data it is found that thick, fine aggregate apparent density, loose bulk density, clay content meet《Normal concrete
With sand, stone quality and detection method standard》, but discarded paving brick is after artificial treatment is broken, and fine aggregate belongs to coarse sand, and thick,
Fine aggregate water absorption rate is larger, and when mix-design will consider big water absorption rate problem.
2, there is certain reduction than the general concrete of same levels by the density of aggregate of discarded concrete, thus may be used
To find out, the regeneration concrete studied herein is light compared with the general concrete of same levels, has the characteristics that lightweight.
3, the damage -form of regeneration concrete cubic compressive strength experiment is similar to normal concrete.It is different to be,
It is the concrete of aggregate in compression damage using discarded paving brick, other than having the destruction between coarse aggregate and cementitious material,
The situation that also part of coarse aggregates is rived.This is related with the intensity of paving brick aggregate.When water/gel rubber material ratio is 0.5, then
The cubic compressive strength value highest of growing concrete.After incorporation flyash and polypropylene fibre, the fundamental force of regeneration concrete
Learning performance test value has certain variation.It is added after fiber, each mechanics parameter value raising of regeneration concrete is more apparent.
And the regeneration concrete of a certain amount of fiber of addition, in stress destruction, the peeling of few fragments has preferable whole
Property.But after flyash is added, a part of mechanics parameter value of such concrete reduces, and the constituent of reason and paving brick has
It closes.
Although the elasticity modulus of regeneration concrete, flexural strength and tensile splitting strength value are relatively low.But consider concrete
Component has been mainly compression effect in the structure, and the cubic compressive strength value of two class regeneration concretes and shaft center compression resistant are strong
Angle value is all higher.Therefore it is aggregate using discarded concrete and there is certain reality as the regeneration concrete of aggregate using discarded paving brick
With value.
