Description
Technical field
The invention relates to porous concrete and constructional method thereof with high-voidage, be particularly suitable for using at rivers and creeks shore protection that takes the form of inclined plane and the construction of inclination physical features place, because it has necessary strength and water-permeable, and after construction, can reduce alkali components effectively, make construction place can grow plant in a short time.
Background technology
Up to the present concrete is widely used in civil structure engineering and buildingss such as road as social infrastructure, railway, bay, upper and lower water course, and its use has been made very big contribution for economical, cultural development really., this concrete that is intended to pursue its building function has but caused the destruction to physical environment, human lives's influence actually, has also harmed vegeto-animal existence, so, it is believed that concrete has caused environmental problem.Thereby, recently in city development and make aspect the scape engineering, in order to realize allowing rainwater infiltrate naturally and revert to the purpose among the soil, people making great efforts to develop apparatus have specific characteristics can the technology of concrete laying construction.
The porous concrete is meant by coarse aggregate and adds what grout or the adhesion of mortar things such as (mortar) formed that contain continuous gap and independent space mostly, therefore according to air gap characteristics, concrete characteristic also is very different.
The major requirement of previously used permeable concrete is: have certain bending and stretching intensity and draw Zhang Qiangdu, and can prevent to lay surface generation be full of cracks.
In the ordinary course of things, permeable concrete is that the component ratio according to the size-grade distribution of the aggregate of tight setting and water and cement concerns synthetic, so it is showing full intensity and higher coefficient of permeability.
This aggregate size-grade distribution that is used as the permeable concrete on laying road road surface is: be on the sieve of 13mm in the aperture, the percentage of throughput is 100%; In the aperture is on the 10mm sieve, and the percentage of throughput is 70~100%, is on the 5mm sieve in the aperture, and the percentage of throughput is 10~50%.
On the pavement of road function of being laid, if voidage is too big, though water-permeable is good, bonding force is fragile, and outward appearance is also very coarse, therefore causes the vibration of vehicle easily; Otherwise,,, can cause water-permeable bad again though outward appearance is good if voidage is too little.So above index is a selected optimum granularity after considering multiple factor such as like that., this permeable concrete mainly is that the pavement construction for road etc. provides as everyone knows, rather than it is used to aim at the construction at rivers and creeks shore protection and inclination physical features place.
The construction at rivers and creeks shore protection and inclination physical features place should be considered to allow plant grow.Up to the present, although various porous concrete is being developed always,, the still untapped pavement material that goes out to be suitable for as inclination physical features places such as riverss and creekss.So up to the present, the construction at rivers and creeks shore protection and inclination physical features place relies on the bulk barrier (block is hereinafter to be referred as " bulk noncombustibility ") that shore protection is used always.Before the concrete exploitation that the space is arranged, with on the history of bulk noncombustibility, be to use general concrete to make at this shore protection always.So just merely in order to prevent the etch of dykes and dams, and the condition that can not provide plant to grow up.Recently, environmental protection problem is on the rise, so the bulk noncombustibility that shore protection is used is also seriously proposed as destroying rivers and creeks environment and natural reason.
In order to address the above problem, we once proposed the technical scheme of " be suitable for plant and give birth to the porous concrete bulk barrier of planting ".(Korean Patent Publication No.: 10-2001-27247 " is suitable for as the porous concrete bulk barrier of giving birth to the phytyl plinth "; " the Korean Patent number of declaring: 10-1999-35489: " ecological stabilization bulk barrier ").
These porous matter bulk noncombustibilities are a kind ofly to be formed by the concrete manufacturing, have 15% the voidage and the structure of specified shape, therefore, can allow native sand fill its space, and plant just can rely on the native sand of filling in the place, space and take root growth.; in order on the rivers and creeks, to use this living concrete bulk noncombustibility of planting of plant that is suitable for; at first to make bulk noncombustibility; for this reason, the space that can produce and store must be ready to, also the working-yard will be transported to then; and bulk noncombustibility in the plane connection or up and down the construction operation such as stacked between the aspect all be that existing machinery can not be finished; therefore must rely on fully manually,, and in construction, need to expend the considerable time so construction itself needs great amount of manpower and labor force.Especially plant can't take root growth at the concrete place of bulk noncombustibility, and only the Tu Shachu in being filled into the formed space of bulk noncombustibility just can take root growth, so when construction, must need considerable labor force and time in order to fill native sand, if because wind and rain so cause the native sand flow of being filled to lose, plant just can not regrowth so.
Generally make the used concrete bulk noncombustibility of scape or be the living porous matter bulk noncombustibility of planting usefulness of plant, another problem that they have bar none is exactly when interconnecting, have the space between piece and the piece, so, the earth below the porous matter bulk noncombustibility is often just from slowly having run off here.Also have, general fluid is when mobile, the section that fluid passed through is narrow more, it is fast more that velocity of flow will become, therefore, and the shore protection place that is not being had by water logging, when current flowing or reflux course in, when passing through the connection gap of bulk noncombustibility, tend to cause native sand flow to lose, cause caving in of dyke fortification so probably because of flow velocity accelerates.So they do not possess the shore protection function.
Summary of the invention
The objective of the invention is to utilize existing material, having under the matching requirements of qualification, develop porous concrete and the constructional method thereof with new effect different with former permeable concrete, it is used at the construction material as rivers and creeks shore protection and slope physical features place, during construction, can fully demonstrate outstanding physical properties, especially the soil that makes the paved surface below is under the maintenance of new concrete, alkalinity reduces day by day, and can make plant give birth to the special efficacy of planting and taking root growth early.This special efficacy is produced by the present invention who portland cement (portland cement) and blast furnace slag (slag) cement mixing is got up and form.
With reference to the accompanying drawings the present invention is described in detail:
The present invention's effect in the construction at as shown in Figure 1 rivers and creeks shore protection or inclination physical features place (especially at inclination physical features place) is the most remarkable.
Produce according to the present invention and the concrete constitutive characteristic of porous be: every cubic metre concrete material is by 260kg/m
3~340kg/m

3Mixture constitute.Promptly; porous concrete among the present invention is a mixing effect of utilizing portland cement and blast furnace slag cement; make its " maintenance " (promptly refer to when concrete construction place lay finish after; need its paved surface covering protection get up be waited for its stiff and be combined as a whole fully protection stage with plastics film) in or after " maintenance "; make the alkali components neutralization in during one, thereby can make plant can take root growth in a short time.Originally simple with portland cement during as embankment material, can emit certain alkali components in during certain, neutralize this alkali components and obtain the effect of needed intensity thereby just reached after anti-growth that does harm to plant and the blast furnace slag cement mixing.
In the present invention, the ratio of grout approximately with account for 24~35% of weight constitute the most suitable.This is meant the portland cement that comprised in every cubic metre the concrete mix and the weight of water, should be equivalent to 260~340kg, if it is ideal to remain on 270~320kg.If cement amount is about more than the 340kg, so, can be said to be passable as the requirement of strength of general People's Bank of China or motor road, still,, will make effective porosity reduce, and cause the life of plant to plant difficulty if as purpose of the present invention; Otherwise, if the not enough 260kg of cement amount will cause insufficient strength.
The present invention compares with general porous concrete, and cement weight is reduced more than 10%, and, the usage quantity of water is also reduced simultaneously, thereby can keep needed intensity.
If the shared weight of the water yield, will can not be guaranteed the plant that can make that the present invention will obtain owing to the increase of the water yield up to more than 35% and give birth to the space of planting; If but the shared weight of the water yield is below 24%, the difficulty that stirs in the time of then can causing the mixture preparation again.
Table 1 and table 2 have shown the present invention's best example in use and the result who measures according to such example.

Said aggregate among the present invention is that the percentage with the sieve throughput limits, and on the granularity category, with approaching numerical value and the water permeability of lower limit confidential relation is arranged, and especially the condition of planting with the plant life has direct relation.Therefore,, on the one hand plant can be grown, just must fully take into account the blending ratio between the different aggregates with fine granularity and coarsness, and carry out suitable adjusting if want to improve on the one hand the essence voidage.
In layings such as road, in the general employed rubble, comprising the rubble of a large amount of disengaging nominal granularity categories, and this there is one of condition of substantial connection just with water permeability.So the material that uses as aggregate according to the present invention is adding man-hour, need consider that this situation decides the cooperation ratio of whole aggregates, perhaps earlier rubble is washed, fine-grained sand mentioned above is disposed in advance.In addition, on the granularity category of the aggregate that the percentage with the sieve throughput limits, the intensity of concrete structures near the numerical value major decision of the upper limit.
Required interpolation mixture among the present invention, can use and it is generally acknowledged all jointing materials (binder) that are applicable to as cement plaster interpolation mixture, wherein, comparatively it is desirable to from AE water reducer, high-performance water reducing agent, retarding agent, flowing agent, SBR latex rubber (1ater), acrylic resin (acrylicresin), silicon-dioxide (silica fume), and select one or more in the material such as cellulosic toughener, use as adding mixture.
The possible feature that the present invention brings the permeable counting of porous concrete structures is: can have 20~40% high voidage.The structures that use the high-voidage porous concrete produced according to the above-mentioned ratio of mixture of the present invention to be built simultaneously not only as previously mentioned, demonstrate very high voidage and water-permeable, and under the field condition after construction finishes, make and can bear 100kg/cm
2~300kg/cm
2Pressure.
The mixture of portland cement proposed by the invention and blast furnace slag cement accounts for 50~99% of gross weight with portland cement, and blast furnace slag cement accounts for 1~50% ratio of gross weight for the most desirable.Because blast furnace slag cement has the weakness that reduces concrete strength,, only under the condition identical, just can reach only intensity and counteragent with above-mentioned mixture ratio so it is extremely important with the mixture ratio of portland cement.
According to such ratio and multiplying power, can fully guarantee the tolerances of above-mentioned pressure, guarantee desirable high voidage simultaneously, and can also prevent the generation of alkali components, thereby, could make plant can take root growth early as shown in Figure 2.
