Description

Non-slip color polymer cement composition and packaging method thereof {Colored and nonskid cement composition and pavement method of the same}

The present invention relates to a color polymer cement composition for road paving and a road paving method using the same, as well as long construction periods, disadvantages in driving comfort, degradation of cracking and plastic deformation, which are disadvantages of conventional cement concrete or asphalt concrete roads. The present invention relates to a road paving material and a method of paving the same, which improves a problem in which color expression, which is a disadvantage of color asphalt concrete, cannot be sustained. In the present invention, it is excellent in clarity and can be aroused by the driver's alert through the color, the high friction has the feature that can be suddenly stopped in the event of a sudden occurrence of the school zone around the school, frequent crosswalks, crossroads, intersections, etc. The present invention provides a color polymer cement composition for paving the road and a method for paving the road, which is suitable for the following and is excellent in durability, so that it can be applied to roads with high traffic volume, especially roads with heavy vehicles.

In areas where special attention is required for traffic safety, such as school zones around schools, signs, speed bumps, etc. are installed, and the roads are paved with colored asphalt concrete to help drivers control the speed. In addition, even in areas where only specific vehicles can enter, such as bus lanes, the road is paved with colored asphalt concrete to attract the driver's attention. However, in the case of the conventional color asphalt road pavement material, not only the color appearance period is not long, but also there is a problem that is vulnerable to plastic deformation, so that the identification ability decreases over time and the risk of an accident due to the deformation of the road increases, so that frequent maintenance is required. There was a difficulty in managing the roads, such as the inconvenience caused by traffic jams.

In addition, pavement using color semi-rigid road pavement is increasing in parks, bicycle paths, sports facilities, sidewalks, etc. in order to revitalize the city's aesthetics and to ensure the safety of pedestrians. Not only fall, but the color appearance period is short and there was a problem in plastic deformation.

On the other hand, rigid color road pavement has the advantage of excellent durability, but there is a limit that the color expression ability is significantly reduced in addition to the disadvantages that the bending performance can be cracked on the road and a lot of dust and noise occurs.

Therefore, to improve the shortcomings of the color road paving material, the development of color cement paste excellent in warpage and excellent in colorability, brightness, adhesiveness is urgently required.

The present invention is to solve the problems of the conventional road paving material, and because of the high frictional force is possible to sudden braking in the event of an accident, not only suitable as a bus stop or road entrance, intersection, roadway paving material, but also excellent in color The purpose of the present invention is to provide a packaging material suitable for a safety zone including a school zone, a bus lane, a bicycle lane, and a method of packaging the same.

In addition, the present invention has excellent load resistance and abrasion resistance, as well as pavement such as roads, loading docks, parking lots, garages, factories, etc., which are heavy in traffic, and also suitable for places where aesthetics such as parks, plazas and rest areas need to be considered. The purpose is to provide a method.

In order to achieve the above object, the present invention provides a color polymer cement composition and a road paving method using the same in two forms: color semi-rigid paving and color anti-slip paving.

Color polymer cement composition according to the present invention has the characteristics of anti-stiffness, anti-slip in common, but in the case of color semi-rigid paving, it is suitable for the surface pavement of the road, anti-slip paving is used on the surface of the existing road It is suitable for processing. Of course, the color semi-rigid packaging and the anti-slip packaging according to the present invention may be used in parallel, and after applying the color polymer cement composition of the present invention, the surface may be roughened by using a surface treatment material to further increase the anti-slip effect. Improve.

The color semi-rigid packaging color polymer cement composition of the present invention is composed of 60 to 75% by weight cemented carbide cement mixture and 25 to 40% by weight water-soluble polymer mixture.

The cemented carbide cement mixture is ultra-fine cement (cement having 4000 ~ 6000 ㎠ / g powder) 50 ~ 60% by weight, blast furnace slag 20 ~ 30% by weight, calcium carbonate 10 ~ 15% by weight, aluminate rapid economic 5 ~ It consists of 10% by weight, 1 to 2% by weight of aluminate expanding agent, and 1 to 2% by weight of fluidizing agent. The ultra fine cement is characterized in that the powder is 4000 ~ 6000 ㎠ / g and the powder is high compared to the powder of 2500 ~ 3500 ㎠ / g of the general cement, and because of this the hydration reaction proceeds quickly when contacted cement The initial strength of is very high. Blast furnace slag and calcium carbonate are inorganic fine powders to enhance the long-term strength of cement and
Dense hydration tissue enhances chemical durability. In the case of aluminate rapid economics, the reaction rate is very fast when contacted with water, and when mixed with cement, it can obtain the compressive strength obtained over several tens of days from ordinary cement, and the aluminate expanding agent dries due to rapid hydration reaction. By suppressing shrinkage, it serves to prevent the occurrence of cracks and the deterioration of durability.

The water-soluble polymer mixture is 75-82% by weight of a polymer dispersion (50-60% by weight aqueous solution) selected from acrylic resin or SBR resin system, pigment 6-12% by weight, antifoaming agent 1-2%, dispersant 0.5-1 It consists of weight%, thickener 1 to 2% by weight, water reducing agent 1 to 2% by weight, hydrating delay agent 1 to 2% by weight, leveling agent 2 to 3% by weight, shrinkage reducing agent 0.5 to 2% by weight. The polymer dispersion selected from the acrylic resin or the SBR resin gives a ductility when the color polymer cement composition is cured, thereby expressing flexural strength as much as possible, and improves adhesion strength and chemical durability, thereby improving durability of the color polymer cement composition. Do it. Antifoaming agent minimizes bubble generation when mixing and injecting materials to make the structure of color polymer cement composition dense, and dispersing agent can maintain uniform quality by dispersing cemented carbide and color pigment evenly. It helps workability, smoothing agent serves to improve the self-filling effect, shrinkage reducing agent is added to prevent the dry shrinkage phenomenon when the color polymer cement composition is cured. In the case of pigments, various color pigments are used for road identification, and inorganic pigments are used to prevent discoloration by ultraviolet rays.

In the present invention, the above-described mixing ratios are not absolute, but if the ratio is out of the above range, the compressive strength, the bending strength, the adhesion strength, the clearness, etc. may fall, so it is preferable not to depart from the above range.

Asphalt concrete for color semi-rigid paving consists of 3-7% by weight of asphalt binder, 65-80% by weight of coarse aggregate, 10-25% by weight of aggregate, and 3-10% by weight of filler material. When laying the asphalt concrete on the road, the porosity is preferably within the range of 15 to 25% in consideration of the saturation, stability, and plastic deformation of the road, the cost increases if a large amount of asphalt binder is added, too If a small amount is added, it does not play a role of the binder, so it is preferable not to deviate from the above range. In addition, the coarse aggregate particle size 13mm ~ 4 mesh to directly support the load serves to suppress plastic deformation, fine aggregate aggregate particle size 4 ~ 200 mesh serves to fill the gap between the aggregate and transfer the load, the fill material particle size Is 200 to 500 mesh, and serves to adjust the porosity at an appropriate ratio, in order not to deviate from the range of the porosity, the weight ratio of coarse aggregate, fine aggregate, and filling material (3 ~ 7) :( 10 ~ 25) :( 65 ~ 80) It is desirable not to deviate from the range of.
