Description of the Invention: [Technical Field of the Invention] The present invention relates to a concrete composition, and more particularly to an alkali/toned pervious concrete composition. [Prior Art] In recent years, urban development has been rapid, and forests and bare land have been reduced. Instead, urbanization of high-rise buildings, tarmac, and reinforced concrete has been replaced. These tar, reinforced concrete and other materials have a fast heat absorption and a small heat capacity; therefore, compared with the general soil below, after absorbing the same solar radiation, not only the temperature rises quickly but also the heat is easily stored; And the hot air and exhaust gas emitted by the traffic, and the flow of hot air is blocked by the buildings that are everywhere. Moreover, due to the use of a large amount of concrete and tar, the soil is seriously lacking in gas permeability, regulating heat and rainwater penetration, resulting in urban temperatures much higher than in the suburbs, forming the so-called urban heat island effect; therefore, development The permeable concrete is made into a pervious pavement, which is one of the main methods used by civil engineering related fields to solve the aforementioned heat island effect. Generally, the structure of the permeable pavement is based on the aggregate as the main skeleton, and the aggregate between the aggregates is cemented as a binder, so that the adjacent aggregates are cemented together in a point-to-point manner, wherein the cement is cemented together. The layer is attached only to the surface of the aggregate and leaves pores between the aggregate particles to form a water permeable passage to allow moisture to flow out through these permeable paths. In general, in order to achieve high water permeability (water permeability coefficient > 0.01 cm/sec), the slurry filling porosity is controlled to be 7 〇 to 9 〇%, so that the permeable permeable surface has enough pores of 201136860 to form permeable water. Path to increase water permeability. However, since the aggregate particles are connected to each other via the slurry as a cement layer, when the permeable pavement structure is subjected to an external force, the external force is mainly transmitted through the cement layer, so that the porosity is increased in order to maintain high water permeability. At lower slurry dosage, the failure surface is likely to occur at the interface between the aggregate particles, which may cause the disadvantage of insufficient compressive strength. Therefore, generally the permeable concrete cannot be used in structural concrete or the compressive strength is high. The road surface is mostly applied to pavements with low compressive strength requirements such as pedestrian walkways, parking lots or parks; for example, the 28-day compressive strength of general permeable concrete is about 1.4 to 14 MPa, and the structural concrete required for the project is 28 The compressive strength of the day should be above 21 MPa, and the 28-day compressive strength of the rigid pavement used on highways or airstrips should be above 35 MPa. In order to solve the shortcomings of the above-mentioned water-permeable concrete, Yang Zhixiang and others (the 2004 industrial environmental protection X-process practical technology seminar papers, the electric arc furnace furnace resources resource in the permeability of the pavement construction # feasibility study) revealed a The electric arc furnace furnace is composed of permeable concrete with the size distribution of 19 and the fine aggregates. The test results show that the water permeability of the permeable concrete floor tiles made of the permeable concrete is It meets the specifications of the High Performance Permeable Green Building Materials of the Ministry of Interior Architecture (permeability coefficient > MO 2cm/sec) and reaches η~12χ1〇-2(10)/coffee, and its 28-day anti-wear strength can reach about 26MPa '·however' The results of compressive strength show that although the compressive strength is higher than that of the concrete-like material of the phase-like material, it is still only applicable to the pavement of the sidewalk or bicycle lane with less resistance to the strength. Wide range of applications are used on other roads with higher strength requirements on 201136860 roads, and because permeable bricks are prefabricated unit components that cannot be used with steel bars, their flexural strength is not Meet the requirements of the road pavement. According to the above description, how to develop a water-permeable concrete with good water permeability and high compressive strength can be widely applied to various road surfaces, so that the soil can maintain sufficient water content more effectively, in order to promote the earth. The ability to recycle water and improve the ecological environment is an important issue that the technical field needs to study.

Furthermore, the unit pore volume (V) algorithm is that after the aforementioned bone material having a predetermined particle diameter is densely filled with a unit volume of the container, the 201136860 container: the weight of the aggregate is weighed again. The weight of the material is divided by the specific gravity of the aggregate p%% to the volume occupied by the monthly material, and the unit pore volume is obtained by subtracting the volume of the aggregate from the unit volume. The aggregates of the crucibles used in the examples: A and granules; ^ B, after calculation, respectively, the porosity per unit pore volume was 45.14% and 36.77%, respectively. The alkali activation liquid is obtained by mixing an alkali activator with water, wherein the alkali activator is selected from the group consisting of sodium citrate, sodium carbonate, sodium hydroxide, sodium hydrogen hydride, or sodium fluoride, and an alkali activator is used. The dissociated anion reacts with the aggregate formed by the furnace, and the slurry and the aggregate can be tightly combined, and since the furnace is a porous material, the slurry penetrates into the furnace before it is hardened. Within the pores, when the slurry is hardened, an indentation effect is formed, which further increases the strength. In the present embodiment, the alkali activation liquid is prepared by sodium citrate and sodium hydroxide, SiO 2 = l 〇 6 g / L, Na 2 O = 105 g / L, alkali modulus: Si02 / Na20 =1 · 01. Since the permeable concrete composition of the present invention uses the granitic slurry activated by the alkali as a bonding material, it has a higher bonding strength than the general cement slurry, and because the furnace itself has an alkali-activated slurry. The ability of the hydration product to produce a pozzolan reaction is more closely combined with the reaction between the grit and the slurry, and the strength can be further improved. Moreover, since the slag itself is a porous structure, the slurry can further penetrate into the pores of the furnace itself, and after the reaction is solidified, a calaming effect is formed, and the strength can be effectively increased, and the amount of the slurry is also used as a unit pore volume ( V) is 0.7 to 0.9 times, and the expansion amount of the absorption furnace in the void space 201136860 can be reserved to reduce the expansion problem after the furnace reaction is solidified. In addition, it should be noted that in order to meet the construction requirements of the project, the permeable concrete composition must have sufficient viscosity. When the test activates the slurry of the permeable concrete composition, the alkali activation liquid (w) and the furnace stone powder (s) When the ratio of content (w/s) is too low, Gu Yi will cause the permeable concrete composition to be too dry and hard at the time of mixing, resulting in the difficulty of using the 5 permeable concrete composition in the foundation project, and also causing the aggregate. The cluster phenomenon makes the overall structure uneven, and the valley leads to the pores of the subsequently obtained permeable product being blocked and losing its water permeability; on the contrary, when the ratio of the alkali activation liquid (w) to the whetstone powder (s) content If the (w/s) is too high, the fluid permeability of the permeable concrete composition is too high, and it is easy to cause a vertical flow phenomenon due to its own weight during sintering or pouring, resulting in the upper half of the overall structure of the permeable product obtained. The slurry coating is insufficient, and the pores in the lower half are completely filled by the slurry element, thereby losing the water permeability. Therefore, preferably, the ratio of the alkali activation liquid (w) to the whetstone powder (s) content (w) /s) is between 0.3 and 0.45 More preferably, the ratio (W/S) of the alkali activation liquid (w) to the calcined powder content is between 0.35 and 0.4. In detail, the permeable concrete composition is prepared by mixing an alkali activator with water and uniformly obtaining an alkali activation liquid for use; and then mixing the aggregate with the hearth powder, stirring to sufficiently uniformly mix the same, and then The alkali activation liquid is added to the agitation to form a slurry of the alkali activation liquid and the hearth powder, and the slurry is uniformly coated on the circumferential surface of the aggregate to obtain the pervious concrete of the present invention, and the product and the water permeation of the present invention The concrete composition can be directly paved for pavement laying, or it can be prefabricated into a permeable unit such as a permeable brick, and then spliced into a plurality of permeable bricks to form a permeable paving surface, and is composed of the water-concrete composition of the present invention 10 201136860 The permeable product has reached the target of 28 days compressive strength of 35 MPa, so it can be widely used on road pavements with different needs. It is worth mentioning that the permeable concrete composition of the present invention may further comprise an additive to meet its specific needs, for example, a retarder, a thickener, a reinforcing agent, a water reducing agent, or a combination thereof may be added, thereby adjusting the The efficacy requirements of the hardening rate, viscosity, bonding strength and the amount of water used for the permeable concrete composition are selected because the structure type of the thickener, the reinforcing agent, and the water reducing agent is well known to those skilled in the art. It should be noted that, in this embodiment, the alkali-activated permeable concrete composition may further comprise a retarder selected from the group consisting of 0.74 M phosphoric acid to slow the phenomenon of rapid solidification of the alkali-activated furnace stone slurry. Since the whetstone itself is a porous material, the permeable product composed of the alkali-activated permeable concrete composition of the present invention, the external water can be formed not only by the pores formed by stacking the furnace The outward flow out can be seen through the pores of the furnace itself, and the water permeable path made by the traditional permeable concrete can only be different through the pore flow between the aggregate particles, therefore, The water permeable product composed of the alkali-activated permeable concrete composition of the present invention can have superior water permeability. The present invention utilizes a furnace stone slurry activated by alkali as a bonding material, and the chemical composition of the hardened solid is formed into a zeolite-like structure in addition to the calcium silicate hydrate similar to the cement slurry currently used. The strength of the slurry can be stronger than that of the general cement slurry. In addition, with the single-stage furnace granule selection and the porous nature of the furnace itself, the polymer can be infiltrated into the furnace 11 201136860. And after the reaction is solidified, a click effect can be formed, which can be more effective to raise the south strength, and a water-permeable product which can simultaneously have both water permeability and high compressive strength can be obtained; and the permeable concrete composition of the present invention can be cast. It can be used in combination with steel bars, so that the anti-f strength required for pavement design can be achieved, so the object of the present invention can be achieved. However, the above is only the preferred embodiment and the specific examples of the present invention, and + can limit the scope of the implementation of the present invention as a simple equivalent change according to the scope of the invention and the description of the invention.
