Abstract
This invention relates to a rubber concrete technology of reducing vibration and noise that used in civil engineering, road works. The invention use the largest diameter of 15mm rubber block instead of part aggregate, rubber volume content is 13 ~ 17% of coarse aggregate volume content. Though compare with ordinary concrete of same configuration, this invention has little lower slump, but in the construction process slump can be adjusted by the amount of slurry, make this concrete easy for construction and meet the construction requirements; Also reached reducing vibration and noise effects. In addition, the incorporation of scrap rubber, solve the high cost of handling scrap rubber and pollution problems.
Description
Technical field
The present invention relates to civil engineering work, a kind of rubber concrete for reducing vibration and lowering noise technical field that road engineering is used.
Background technology
Along with development and national economy, waste rubber product is increasing, according to statistics, nearly 2,000,000 tons of the present year consumption of rubber of China, recovery utilization rate is less than 30%.Waste rubber is difficult for degraded, and the pollution to environment behind the landfill is bigger, burns and also can bring topsoil, how to handle the waste rubber that increases day by day and become a serious environmental problem, simultaneously, if can not the reasonable use waste rubber, also can cause a kind of waste of effective energy.
With rational particle diameter, rational proportion adds in the concrete, substitutes the part aggregate in the concrete, can allot the rubber concrete that satisfies the highway construction requirement rubber.Characteristics such as the flexible modulus of this kind concrete is low, and it is effective to consume energy, and plastic property is good are used for the impact force that highway pavement can alleviate vehicle and road surface, can play the function of vibration and noise reducing.This concrete on intensity a little less than normal concrete, but can satisfy the requirement of strength of highway concrete, this concrete has better deformability than normal concrete, prevents that aspect such as thermal cracking also is better than normal concrete.
The rubber concrete rubber powder volume of existing report is generally all bigger, and the conclusion that different investigators draws differs also very big, but all can not be applied in the actual engineering.
Summary of the invention
The purpose of this invention is to provide a kind of rubber concrete for reducing vibration and lowering noise that can be applied to actual engineering road surface, this kind concrete makes waste rubber turn waste into wealth simultaneously, the high problem such as big for environment pollution of expense when having solved waste rubber and handling.
Rubber concrete for reducing vibration and lowering noise of the present invention is the block rubber instead of part coarse aggregate of 15mm with the maximum particle diameter, and wherein the volume content of block rubber is 13～17% of a coarse aggregate volume content.
Rubber concrete for reducing vibration and lowering noise of the present invention, other set of dispense is than getting final product according to the technology that requires among " highway cement concrete pavement design specifications " (JTG D40-2002).
Described coarse aggregate is meant the stone that the road surface is used always with concrete, and its volume requires to remove part alternate block rubber, and other is all according to the routine techniques requirement.
Beneficial effect of the present invention: be mixed with the rubber concrete that maximum particle diameter is the block rubber of 15mm, though the slump of its mixed material can slightly reduce than the normal concrete of identical configuration, but in construction process, can adjust slump by the consumption of regulating grout, make this concrete be easy to construction, satisfy the engineering construction requirement; Also reached simultaneously the effect of vibration and noise reducing.In addition, in concrete, mix the waste old piece, problems such as expense height and environmental pollution when having solved the waste rubber processing.
Description of drawings
Fig. 1 is the size distribution figure of concrete medium sand, stone, rubber grain.Containing ratio is the accumulative total sieve percent of pass that standard sieve is analyzed among the figure.
Embodiment
According to " highway cement concrete pavement design specifications " (JTG D40-2002), concrete design objective strength grade is C35.Through experimental study, draw following proportioning and meet the demands, the configuration raw material is: cement uses ordinary Portland cement, label 425; Sand is river sand, maximum particle diameter 4mm, cobble-stone diameter 5-31.5mm; Admixture is N-5 high efficiency water reducing agent (water-reducing rate is 10%-15%).Rubber is the 15mm block rubber.The embodiment of concrete proportioning sees Table 1, and various material permissible variations see Table 2 in the layoutprocedure.The set of dispense ratio that process is joined in the examination that is mixed with the rubber concrete of 15mm particle diameter block rubber sees Table 3.Sand, stone and block rubber particle size range are seen Fig. 1, containing ratio is the accumulative total sieve percent of pass that standard sieve is analyzed among the figure.

| Admixture (kg/m 3) | 1180 | 4.01 |
| 15mm block rubber (kg/m 3) | 1147 | 75.8 |
The volume content of block rubber accounts for 15% of stone volume content in the foregoing description.

| Intensity | 53.54 | 43.51 | 29.83 | 21.92 | |
By above each example as seen, be mixed with after the block rubber in the concrete, intensity also can reduce than normal concrete, under the proportioning of block rubber volume 15%, the rubber concrete cubic compressive strength is 43.51MPa, and prismatic compressive strength is 25.3MPa, Young's modulus is 23.6GPa, tensile splitting strength is 3.84MPa, and folding strength is 4.53MPa, Poisson's ratio 0.28.
Concrete stirs and making is all carried out by " highway cement concrete pavement construction technique normalizing " JTG F30-2003.Be mixed with the rubber concrete of 15mm particle diameter block rubber, the slump of its mixed material can reduce than the normal concrete of identical configuration, can adjust slump by the consumption of regulating grout in construction process, makes this concrete be easy to construction.
The vibration situation of vehicle mainly is subjected to the excited frequency and the road surface natural frequency influence of vehicle, and the excited frequency of vehicle road pavement is generally than road surface frequency height.Theory and practice proves that it is far away more that vibrating object natural frequency and excited frequency differ, and object is not easy to vibrate more, so reduce the pavement concrete vibrational frequency vibration of vehicle is reduced.After the road surface reduced the vibrating effect of vehicle, under identical vehicle and surface evenness situation, the friction noise on vehicle and road surface will reduce.
With the block rubber volume content of 15mm (maximum block rubber particle diameter is 15mm) particle diameter be coarse aggregate altogether the concrete of 15% this embodiment of volume content do test, concrete sample is 100mm * 100mm * 1000mm.Rubber concrete sees Table 4 to the effect that reduces of vibration.The rubber concrete road surface can reduce 2-3 decibel than Common Concrete Pavement noise.
Table 4 rubber concrete damping test result
| Concrete | Fundamental frequency | Second order frequency | Three order frequencies | |||
| Simply supported beam | Socle girder | Simply supported beam | Socle girder | Simply supported beam | Socle girder | |
| Common | 173.84 | 72.36 | 646.61 | 424.21 | 1329.19 | 817.04 |
| Rubber concrete | 157.55 | 65.02 | 691.73 | 411.50 | 1254.66 | 785.64 |
By above test and test result as seen, the block rubber volume is that about 15% rubber concrete can satisfy actual road simultaneously with the effect that requires with vibration and noise reducing at the coarse aggregate volume content.
