The present invention relates to a method for manufacturing an environmentally friendly low-toxic revetment block and a relieving block thereof, and more specifically, the revetment block contains minerals that can neutralize the toxicity of cement, while preventing the pollution of rivers. The present invention relates to an invention capable of activating the composition of a vegetation colony growing in a block.

In general, a shelter block is installed to protect the slopes of slopes and cuts of slopes and roads of rivers and coasts, and is a slope in response to the flow velocity of the river or concentrated rainfall. Soil is effectively prevented from falling down the soil.

However, since the above-mentioned revetment block is formed to be bonded to each other on the inclined surface after injecting the concrete into the form and molded into a specific shape, the closed end such as causing toxicity by cement.

In other words, the cement emits a large amount of carbon dioxide when it comes in contact with water, and is composed of strong alkalis to elute toxic substances for a long time. Therefore, the cement pollutes the river until the toxicity of the cement is completely discharged. In addition, the creation of vegetation colonies growing in Hoan Bloc could not be made actively.

Furthermore, the cement when the moisture given cement cured body of water-soluble components are CaCO3, Ca (OH) in the process of moving to the surface 2, Na2SO4, K2SO4, hydroxyl toxins, such as CaSO4, Na2CO3, K2CO3 to water (OH ^-) contained in the By the hydration reaction to react with ions, whitening precipitates and slowly whitening of toxic substances occurs.

This bleaching is to weaken the structure of the revetment block by corroding the reinforcing steel frame embedded in the concrete. Therefore, after the installation of the relieving block, the reinforcing bars are corroded after a certain period of time. Occurred.

The present invention was devised in view of the above problems, and its object is to contain minerals that can neutralize the toxicity of cement in the raft block, thereby preventing pollution of the river, and growing in the raft block It is to provide an environmentally friendly method for the production of low toxicity lanthanum block that can activate the composition of the community.

A feature of the present invention for achieving the above object is illite which is a monoclinic mica family mineral, and chlorite which is a mineral belonging to a monoclinic system ( Grinding dolomite, which is a mineral of trigonal and trigonal systems, into fine powder and filtering the fine powder by sieving the particle having a particle size of 150 mesh or less; 19 to 21% by weight of cement, 19 to 21% by weight of sand, 29 to 31% by weight of aggregate, 9 to 11% by weight of illite, 6 to 8% by weight of chlorite, 3 to 5% by weight of dolomite, admixture 1.5 After mixing evenly-2.5% by weight 6 to 8% by weight of water to knead evenly; Molding the kneading block by applying vibration while putting the kneaded concrete into the mold of the sieve block; It can be achieved by the environmentally friendly low-toxic anti-foam block manufacturing method characterized in that it consists of a step of curing for 3 to 5 days by putting the molded relief block into a curing room maintaining 30 to 40 ℃.

The vibrator was placed on the top of the support to be supported by the coil spring, the concrete is injected into the mold and the vibration is mounted on both sides of the support by vibrating the support to give a vibration to the concrete to be compacted, the vibrator is eccentric cam on the rotating shaft of the motor This mounted normal vibration device was used.

Subsequently, the molded relief block was put into a curing chamber maintained at 30 to 40 ° C. to cure for 3 to 5 days to complete the relief block.

On the other hand, in some cases, the molded revetment block 10 may be put into a curing chamber maintained at 25 to 65 ° C. to cure for 12 hours while spraying steam for 5 to 7 minutes every 1 hour. It is not limited to.

Compressive strength of the finished revetment block by the above-described manufacturing process is more than 180kg / cm2 appeared to be good durability and wear resistance, the natural stone pattern is formed in the mold formed by the engraved and embossed natural stone pattern is well represented natural stone texture The high quality revetment block is completed.

2 to 3, as shown in Figure 2 to 3, the natural stone texture is expressed on the surface of the body constituting the rectangular parallelepiped, and the outer surface is formed around the coupling spheres (11) forming a triangular coupling sphere other revetment block Engaged in combination with each other (11) of the coupling holes (11), the guide holes 12 are vertically drilled on both sides of the body to form a cover for the vegetation (覆土), through the sides of the body The drilled hole 13 is coupled to the binding rod 20 and the wire is configured to firmly bind the raft block 10 is continuously coupled.

Test Example 1 Measurement of Deodorizing Effect

The deodorization effect was measured by requesting the ban block completed by the manufacturing process of the present invention to the Korea Far Infrared Ray Evaluation Institute, and the test method is to inject the ammonia gas 500ppm into the container containing the sample and the container without the sample to increase the deodorization rate. Test KFIA-FI-1004 test standard was used.

As a result, as shown in the deodorization rate (%) test result of Table 1, the gas concentration was measured every 30 minutes by using a gas detector tube, and the container into which the sample was put showed a deodorization rate of 88% after the first 30 minutes. Deodorization rate 91% in 90 minutes, 93% deodorization rate in 90 minutes, 94% deodorization rate in 120 minutes, gradually increasing the deodorization rate (%). After about 2 hours, most of the ammonia gas was adsorbed and removed, and the deodorization efficiency was very high. Appeared.

In addition, the deodorization rate (%) was not changed in the container into which the sample was not injected, except for the amount of ammonia gas that naturally disappears as the sample was collected by the gas detector tube.
