Description

TECHNICAL FOR PAVING ROAD OR FOR MANUFACTURING BLOCK WITH CEMENT COMPOSITION TO REVEAL NATURAL STONE TEXTURE}

The present invention relates to a road paving method, and more particularly, to a road paving method and a method for producing a block having a natural stone surface to protrude to the surface such natural aggregates contained as aggregate.

The present invention relates to a method for paving soil and a method for producing blocks having natural stone surfaces protruding from natural stones.

The pavement of modern roads should be durable in human traffic, bicycle and car traffic, free from natural damage in winter and summer, which are natural conditions where climate change is relatively large, and should be composed of pavement that is beautiful and harmless to human body. do.

Conventional road pavement materials include cement pavement, asphalt pavement, resin pavement, etc. When looking at the double pavement, cement concrete pavement, colored (color) permeable concrete pavement, natural stone pavement packaging and the like. Cement concrete pavement and colored permeable concrete pavement using cement are pavement used by mixing cement as an inorganic binder of the aggregate with aggregates of predetermined particle size (such as soy gravel or crushed stone). It is widely used as a pavement pavement in the same safe driving area (slow driving area).

Aggregate with a certain particle size distribution, such as soybeans or crushed stone, is mixed with cement and placed as a packaging material. If the natural aggregate is exposed to the surface where it is visible and visible to the naked eye, the aggregate is a natural natural material. Although it is useful in terms of improving aesthetics, the pavement method of soil having natural stone surfaces with natural stones protruding has not been actively applied to roads.

The natural stone protrusion packing method generally uses aggregates having a size of about 10 mm or less such as natural stones and soybeans, and after mixing cement and water with these aggregates, paving them on the road and spraying them on the surface. It is a paving method that peels off the inorganic material, that is, the cement, which acted as a binding material to bind the aggregates together from the aggregate exposed on the surface of the pavement, so that natural stone protrudes.

However, when spraying water, aggregates float during spraying, so the strength of the surface of the pavement becomes weak, so that it is difficult to walk after curing, and cement + water does not fall off the aggregate so that the amount of water sprayed or high pressure spraying Too many pavements are lost, making them worthless as road pavement. Also, due to the large amount of water spraying, the natural stone pavement packages were hardly activated due to problems such as the pavement being easily damaged in winter.

In addition, as a binder, there is a natural stone resin package that is packaged on the site by mixing organic resins (epoxy, acrylic, urethane) with aggregates, but not with inorganic cement. Falling, the cost of construction is expensive, natural stone should be used to dry, and construction by plastering is slow construction speed, it is recognized as cumbersome packaging.

Therefore, to construct a durable packaging with a natural, natural stone surface,

First, in order to form a variety of particles of natural stone particles to 40mm or less, after installation, compacted by screed compactor, Laura, the lower layer (base layer) to be firmly embedded in the natural stone to reduce the lifting during spraying.

Second, it is required to use as little water as possible when spraying, so it is necessary to spray the cement dispersant so that the cement can be easily separated from the natural stone even if less water is used. Cement dispersions should be compacted after spraying to ensure uniform penetration into cement.

Third, the packaging surface should not be affected by winter with the appropriate amount of AE. The use of AEs allows the cement to separate well from natural stone.

Fourth, in the pasted dough, the cement is less likely to fall off the aggregate surface than the thin dough. Considering the construction year and strength, it is necessary to keep the slump of the packing cement paste within a predetermined range so that the cement can be easily separated from the natural stone when spraying.

Fifth, if necessary, the far-infrared rays are radiated from the pavement surface, and if you want to make the color of the pavement natural, the pavement composition consists of ocher, red clay, black soil, white clay, elvan, mica, charcoal, etc. It can also be used, mixing as one of the materials to make.

Six, the natural stone may be paved only, but the material cost may be high, so the natural layer may be 10 to 70 mm, and as a lower layer (base layer), for example, a concrete layer may be provided. At this time, the material of the lower layer,

① How to lay general concrete and wrap natural stone on top

② Method to install porous or nonporous compacted concrete with slump of 0 ~ 3㎝ by mixing water, cement, sand and gravel, then compacting with Laura or compactor and packing natural stone on it.

③ In the mold, ② is the lower layer, and after vibration or vibration pressurization, natural stone and cement mixture is put into the upper part, and the cement dispersion is sprayed by vibration or vibration spraying to sprinkle the natural stone protrusion block. Can be.

 The present invention provides a road paving method of natural stone protruding and beautiful and far infrared stone is radiated to become a natural-friendly pavement or a method of producing a natural road-friendly paving block by natural stone protruding and beautiful and far infrared is radiated. It is.

The road paving method and the manufacturing method of the block having a natural stone surface according to the present invention is made through the following process.

That is, in the road paving method having a natural stone surface, the lower layer is at least one of an auxiliary base layer, a crusher layer, a concrete layer, a porous concrete, a recycled ascon and a recycled cement concrete layer. Particle size is 2 mm or less with respect to 1 part by weight selected from at least one of natural stone of steel, color aggregate, abrasive stone, feldspar, silica sand or elvan, which passes 100% in mm and passes 0-30% in 2mm. And far-infrared rays are irradiated with soil at least one of ocher, red clay, black soil, white clay, elvan, mica, zeolite, charcoal, and silica sand, to give birth to cement. Mix 0.1 to 0.5 parts by weight of water so that the slump is 5 to 20 cm.

In addition, AE agent is used for entraining air. The amount of AE agent compared to cement is less than 2%, air entrainment is used to be 4-12%, and water-soluble resin is used in the range of 5-30% by weight of cement usage. Used as. This mixed material is installed in the field and the high fluidizing agent is sprayed. The high fluidizing agent is used by mixing with water, and the amount used is 1 to 20 parts by weight of water mixed with 1 part by weight of the high fluidizing agent. It is sprayed 0.01 ~ 0.1kg per m2 of floor area (packing area), and the second compaction makes it easy to separate cement from natural stone by high fluidizing agent.

After the second compaction, spray water to separate the cement from the aggregate so that the protrusion rate of natural stone after spraying is 50% or more.The surface is covered with vinyl, etc. Leave the joint to complete the natural stone overhang pavement.

By the road paving method and the manufacturing method of the block having a natural stone surface according to the present invention it is possible to obtain a block having a natural pavement surface or a pavement having excellent durability or a pavement such a road.

The road paving method and the manufacturing method of the block having a natural stone surface according to the present invention, the subbase layer, crusher layer, concrete layer, porous concrete, recycled ascon or recycled cement concrete layer on the basis of the weight percentage on the lower layer 100 in a 100 mm sieve 100 Percent of 1 parts by weight of at least one natural stone selected from steel gravel, color aggregate, abrasive stone, jongseok, silica sand, and banban stone that pass% and pass 0 ~ 30% in 2mm sieve, the particle size is 1mm or less and far infrared rays are radiated and cement As soil for coloring the site, at least any one of 0.001 ~ 0.2 parts by weight, 0.2 ~ 1.0 parts by weight of cement, slump of ocher, red soil, black soil, white clay, elvanite, mica, zeolite, charcoal or silica sand Use 0.1 to 0.5 parts by weight of water, if possible.

In addition, the road paving method and the manufacturing method of the block having a natural stone surface according to the present invention can further use the AE agent for entraining the air, in this case the air volume by weight percent compared to the mixture of cement and natural stone 4 It is used to be ~ 12%, and water-soluble resin can be used more in the range of 5-30% of the cement usage. Water-soluble resins promote cement bonding, impart elasticity, and prevent cement cracking. If it is less than 5%, it is ineffective. If it is more than 30%, the viscosity is too high and construction is difficult.

As described above, the mixed material is installed on-site, and then a high fluidizing agent is applied to fluidize the cement thereon. The high fluidizing agent is mixed with water. In the mixing ratio with water, 1 to 20 parts by weight of water is mixed with 1 part by weight of the high fluidizing agent to spray 0.01 to 0.1 kg per m 2, and the second cement is cemented on the surface by cement. Easily separated from Cement admixtures with excellent cement dispersing power can be used as various components such as naphthalene polymer, naphthalene formalin condensate as the main ingredient, or melamine formaldehyde polymer as the main ingredient. , M2 and the like can be used.

The compaction is either compacted with a roller or rubbed with a paint roller so that the high fluidizing agent disperses the cement so that the cement can be easily peeled off from the natural stone during spray spraying in the subsequent process.

At the end of the second compaction, spray water to spray the cement away from the aggregate.

By sprinkling in this way, the surface protruding rate of the natural stone is 50% or more, and the pavement surface is covered with vinyl, etc., and then cured for 1 day or more, and then the joint cutting with a diamond cutting machine completes the natural stone protruding pavement.

On the other hand, in addition to the composition (material) as described above, in order to increase the cement strength, workability and strength as necessary, mixed materials such as natural materials and crude steel materials are used, and fly ash, silica fume, pigments, etc. Can be used additionally.

In the present invention, the lower base layer (base layer), such as auxiliary base layer, crusher layer, concrete layer, porous concrete, recycled ascon or recycled cement concrete layer, may be placed below the upper layer to which natural stone is applied for economical packaging. will be. In this double-layer pavement, the upper layer thickness of natural stone pavement is 1 ~ 7cm, and the lower layer is economical by laying compacted concrete or porous concrete mixed with water, cement, gravel admixture, and immediately after compacting. Natural stone overhang pavement can be configured.

In the present invention, the maximum size of the natural stone included in the upper layer is limited to 40 mm because aggregates of 40 mm or more are difficult to produce and construct, and when the 5 mm or less is used by 30% or more, the content of fine aggregates is too high. This increases the number of aggregates during watering and causes surface peeling of natural stones.

If the use of ocher and the like is less than 0.01 parts by weight, there is no change in color and there is no use effect.

If the amount of cement used is less than 0.3 parts by weight, the strength of the package decreases and the protrusion of the natural stone becomes larger, thereby reducing the durability of the pavement. If the cement is used more than 1 part by weight, the cement section becomes larger and the natural stone protrusion rate decreases.

The amount of water is adjusted according to the required slump, and the amount of water used is adjusted according to the slump of the natural stone mixture. When the slump is 3 cm or less (in the case of the bibimb), the cement is not washed well when the natural stone is protruded. It will be used, and the washed water and cement overflows between the natural stone and the natural stone to be discharged to the outside cause of pollution, causing the natural stone to be lifted by a large amount of watering. However, when the slump is 20 cm or more (too thin bibeam), it is not preferable to drop the strength in an excessive amount, so that the water is preferably used in the range of 0.1 to 0.5 parts by weight so that the slump is in the range of 5 to 20 cm.

The use of AE prevents winter frosts, improves the workability of natural stone and cement mixtures, and facilitates natural stone protruding. If the air volume is less than 4%, the effect is weak. Durability is poor.

After laying and compacting natural stone concrete, watering is applied. After the first compaction, the surface is sprayed with a high fluidizing agent and the second roller is compacted. When spraying high fluidizing agent and compacting with Laura, the surface slump of cement + water attached to the surface of natural stone is increased by high fluidizing agent, and more than 30% is peeled off by the water sprayed during compacting. The natural stone will protrude. If the amount of the high fluidizing agent is increased, the surface strength may be affected, so it is necessary to spray the proper amount.The high-plasticizing agent is mixed with water at 1: 1 to 20 parts by weight, and the amount of the high fluidizing agent is applied in the range of 0.01 to 0.1kg per ㎡. Good to use at 0.01 kg or less has no spraying effect, and 0.1 kg or more has a large surface natural stone protrusion rate, which affects the surface strength.
