The present invention relates to a concrete walkway block that is impregnated in a multilayered structure of a closed shell including a shell and a photocatalyst coated on the surface is exposed to a sustained release to reduce fine dust and surface pollution by the photocatalyst, and to maintain an atmospheric purification function.
일반적으로 콘크리트 보차도블럭은 도시미관과 보행 또는 자동차 주행의 편의성을 고려하여 보도나 차도, 주택단지, 광장, 공원, 주차장 등에 연속적으로 배열하여 서로 맞대어 포장된다.In general, concrete pedestrian road blocks are paved facing each other by successively arranging sidewalks, roadways, residential complexes, plazas, parks, parking lots, etc. in consideration of the aesthetics of the city and the convenience of walking or driving.
이러한 콘크리트 보차도블럭으로는 정육면체, 직육면체, 다면체 등 다양한 형태와 점자블럭, 유도블럭, 보도블럭, 차도블럭, 주차장블럭, 광장블럭, 공원블럭 등 다양한 용도로 사용되고 있으며, 통상 보차도블럭은 대부분 시멘트와 모래, 자갈 그리고 물을 일정비율로 적절하게 혼합시킨 후, 그 혼합물을 진동가압성형기를 이용하여 성형하고 양생시켜 제조된다.These concrete pedestrian road blocks are used in various shapes such as cubes, rectangular parallelepipeds, and polyhedrons, braille blocks, guide blocks, sidewalk blocks, driveway blocks, parking blocks, square blocks, park blocks, and so on. , Gravel, and water are properly mixed in a certain ratio, and then the mixture is molded and cured using a vibration pressing machine.
그러나, 현재 보차도에 사용되는 콘크리트 블럭은 단지 포장블럭으로 기능으로만 사용되고 있는데, 최근 대기 중에 부유하는 미세한 입자로 이루어진 미세먼지로 인한 문제가 점점 심각해지고 있으며, 질소산화물(NOx)은 미세먼지를 유발하는 물질로 알려져 있는 바, 특히 도로에서의 자동차 운행 과정에서 상당량이 배출되고 있어 이러한 미세먼지, 질소산화물(NOx) 등의 오염물질이 보차도블럭에 반복적으로 축적되고 오염되고 있다However, the current concrete block used for the sidewalk is only used as a pavement block, but the problem due to fine dust composed of fine particles floating in the air is getting serious recently, and nitrogen oxide (NOx) causes fine dust. As it is known as a substance that, in particular, a significant amount is discharged in the process of driving a vehicle on the road, and contaminants such as fine dust and nitrogen oxides (NOx) are repeatedly accumulated and contaminated in the sidewalk block.
이에 최근 들어 광촉매가 함유된 블록을 이용하여 대기오염물질들 특히, 자동차 배기가스중에 포함되어 있는 질소산화물(NOx)을 제거하기 위한 기술이 개발되고 있는 바, 광촉매 소재가 사용된 부재를 보도블록에 삽입하는 내장식 보도블록 또는 성형 시 시멘트몰탈에 광촉매입자를 첨가하는 일체식 보도블록 등의 제조방법이 알려져 있다. In recent years, a technology for removing air pollutants, particularly nitrogen oxides (NOx) contained in automobile exhaust gas, has been developed using a block containing a photocatalyst. There is known a manufacturing method such as an embedded sidewalk block to be inserted or an integral sidewalk block in which photocatalytic particles are added to a cement mortar during molding.

그후, 굴껍질 폐각을 이산화티탄(TiO2) 미세분말을 물에 혼합한 에멀젼에 침지한 후, 상기 폐각의 다층구조에 이산화티탄(TiO2) 에멀젼이 충분히 합침되도록 2기압으로 5시간 동안 가압한 후, 건조하고 1~8mm 범위의 입자크기로 분쇄하여 광촉매가 폐각의 다층구조에 함침되고 표면에 코팅된 굴껍질 또는 조개껍질을 포함하는 폐각을 제조하였다.Thereafter, the oyster shell closed shell was immersed in an emulsion mixed with titanium dioxide (TiO 2 ) fine powder in water, and then pressed at 2 atmospheres for 5 hours so that the titanium dioxide (TiO 2 ) emulsion was sufficiently incorporated into the multilayer structure of the closed shell. Then, it was dried and pulverized to a particle size in the range of 1 to 8 mm, so that a photocatalyst was impregnated into the multi-layered structure of the closed shell, and a closed shell including oyster shells or shells coated on the surface was prepared.
다음, 백색시멘트 130 중량부, 잔골재 500 중량부, 상기 제조된 광촉매가 폐각의 다층구조에 함침되고 표면에 코팅된 굴껍질 또는 조개껍질을 포함하는 폐각 50중량부, 물 50중량부를 혼합한 표층몰탈조성물을 형틀에 안치된 상기 기층부 상부에 주입하고 진동 가압하여 표층부를 200x200x60mm의 크기로 성형하고 양생하였다.Next, 130 parts by weight of white cement, 500 parts by weight of fine aggregate, a surface mortar in which the prepared photocatalyst is impregnated in the multi-layer structure of the closed shell and 50 parts by weight of closed shell containing oyster shells or shells coated on the surface, and 50 parts by weight of water are mixed The composition was injected into the upper part of the base layer placed in a mold and subjected to vibration pressure to form the surface part into a size of 200x200x60mm and cured.
[본 발명의 콘크리트 보차도 블럭의 물성시험][Physical property test of concrete sidewalk block of the present invention]
상기 성형된 블록의 휨강도[KS F 4419:2001)] 및 NOx 제거 효율 실험(KSL ISO 22197-1)을 측정하고 하기 [표 1]에 나타내었다.The flexural strength of the molded block [KS F 4419:2001)] and the NOx removal efficiency test (KSL ISO 22197-1) were measured and shown in Table 1 below.
상기 [표 1]에서 알 수 있는 바와 같이, 본 발명의 광촉매가 폐각의 다층구조에 함침되고 표면에 코팅된 굴껍질 또는 조개껍질을 포함하는 폐각을 표층골재로 사용한 미세먼지 및 표면오염저감과 대기정화 기능을 가지는 콘크리트 보차도 블럭은 굴껍질 또는 조개껍질을 포함하는 폐각의 다층구조에 함침되고 표면에 코팅된 광촉매가 서방성으로 노출되어 광촉매에 의한 미세먼지 및 표면오염저감과 대기정화 기능이 지속되는 우수한 효과가 있음을 알 수 있다.As can be seen from the above [Table 1], the photocatalyst of the present invention is impregnated in the multilayer structure of the closed shell, and the surface is coated with oyster shells or shells containing shells as a surface aggregate to reduce fine dust and surface pollution and reduce air quality. The concrete walkway block with a purification function is impregnated in the multi-layered structure of the closed shell including oyster shells or shells, and the photocatalyst coated on the surface is exposed to a sustained release, so that the photocatalyst reduces fine dust and surface pollution and maintains the air purification function. It can be seen that there is an excellent effect.
