In order to solve the above problems, the present invention provides a method for paving ground, comprising: a construction preparation step of arranging the ground flat and installing pavement stones at both edges of the ground to display the paving position; Preparing a pavement by stirring 260 kg of zeolite mixed powder consisting of zeolite and quicklime and an aqueous solution of water and an AE sensitizer per 1500 kg of masato; Laying the prepared pavement on the ground between both boundary stones and compacting by pressing the paved pavement with a vibrator; It comprises a curing step; covering the pavement with a curing material so that the pavement compacted on the ground to maintain a wet state for a certain period of time. The present invention may include a step of evenly finishing the surface using a mechanical device such as a vibrator in the case of the wet packaging. Only on dry days, surface finishing should be done using a mechanical device such as a 3.5 ton roller.

The present invention is a natural-friendly packaging method using a zeolite mixed powder that melts well in the Masato component more than cement and is superior in elasticity, adhesive strength, strength, etc. when the components of the existing cement and Masato are fused and cured.

The present invention having such a feature will be more clearly described through the preferred embodiment accordingly.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a packaging process according to the present invention.

As shown, the ground paving method according to the present invention comprises a construction preparation step, pavement manufacturing step, laying and compaction step, curing step, surface cleaning step.

In the construction preparation step, as in the conventional ground pavement construction, the ground is flattened using manpower or construction equipment, and boundary stones (or paving position setting marks) are installed at both edges of the ground.

The pavement manufacturing step is a process for manufacturing pavement to be laid on the ground smoothly arranged through the construction preparation step, wherein the pavement is made of a mixture of the preferred mixture in Masato that can be obtained directly from nature The bar will be described in detail as follows.

According to the present invention, the pavement is made of a mixture of zeolite powder mixed with zeolite (made of zeolite and quicklime), aqueous solution containing AE water reducing agent and then stirred.

Hereinafter, the present inventors exemplify the test values carried out to obtain the desired content and size of the additives. (In the following tables, the contents of each additive is the amount contained per 1,500 kg of masato (volume: 1 m 3)).

In this experiment, the group A and the group B and C having values above and below the group A were compared with the group A, which is an optimal estimate of the content and size of the additive.

First, the test data regarding the zeolite mixed powder content is as follows.

A B C Zeolite Mixed Powder 240 ~ 280㎏ Less than 240kg More than 280㎏ Performance Maintain proper strength, ground and fusion Difficult to expect sufficient strength Increasing strength but creating ground and heterogeneity

           <Performance Comparison According to Zeolite Mixed Powder Content of Paving Soil>

That is, as can be seen in the above table, if the zeolite mixed powder content is less than 240kg, it is difficult to expect sufficient strength, on the contrary, if too much more than 280kg, the strength is increased, but it is difficult to expect the texture of the soil, and existing ground The heterogeneity of the excess occurs, and the problem of incompatibility occurs. In addition, as the amount of expensive zeolite mixed powder used increases, the construction cost also increases.

In addition, the most preferable content of cement in the above range (240 ~ 280kg) was found to be 240kg.

The zeolite mixed powder is a weight ratio of zeolite 7: quicklime 3, and it is important to mix it correctly and evenly by a mechanical apparatus such as a vacuum mixer. Quicklime is alkaline and neutralizes acid, resulting in fine expansion and precision when in contact with moisture. The hardening property takes a seal, but once hardened, the hardening property becomes harder. Zeolites absorb moisture and increase adhesion to minimize cracks.

A B C Quicklime / Zeolite (weight ratio) 3/7 3/7 or less 3/7 or more Performance Proper Strength and Crack Prevention Crack formation and strength drop Titration timeout

        <Performance Comparison According to Content of Quicklime in Comparison with Zeolite>

That is, the quicklime is determined in relation to the zeolite, and the content thereof is determined. In this case, when the ratio of the quicklime and the zeolite is 3: 7, cracking is prevented and the optimum strength is maintained. If the ratio of the zeolite is 3: 7 or less, there is a problem that the strength to the load such as compressive strength is lowered and cracks are generated, and if the ratio of the quicklime and zeolite is 3: 7 or more, the curing time is too long. .

On the other hand, the aqueous solution in the additive is made by adding a certain amount of AE reducing agent to the water, wherein the water is 200l if wet per 1500kg (about 1㎥) Masato, 30l if dry and the AE reducing agent compared to the amount of zeolite It is added to have 0.7% by weight (ie, 0.7% by weight of AE reducing agent based on 100% by weight of zeolite).

Here, the AE water reducing agent will be briefly described. The AE water reducing agent is a surfactant having remarkable foaming properties, and evenly generates small independent bubbles in concrete to prevent freezing and thawing. It improves durability such as disintegration and corrosion resistance, improves the fluidity of concrete, facilitates pouring work, lowers thermal conductivity of hard concrete, and improves water tightness. It is also known to have a secondary effect.

However, if too much is used, it is not only economical, but also various obstacles such as a decrease in compressive strength, a decrease in adhesive strength with other additives such as aggregate and masato, and thus, the amount of addition must be maintained.

In addition, according to the present invention, the pavement contains a certain amount of iron oxide (5 kg per 1500 kg of Masato) or ocher powder (5 kg per 1500 kg of Masato), so that the color of the pavement has a color similar to ocher by the iron oxide contained For sake. Therefore, in order to maintain the color similar to that of yellow clay, yellow iron oxide and red iron oxide constituting the iron oxide should be mixed in an optimum ratio, and the most preferable mixing ratio of yellow iron oxide and red iron oxide is 3: 1 based on volume ratio. to be. Do not use iron oxide when using ocher powder.

Again, in the above-described laying and compacting step, the pavement prepared by the above process is laid on the ground between the boundary stones (packaging position indication) installed at both edges, and the paved pavement is added by using a construction machine. It will be prepared.

In addition, the curing step is to keep the pavement compacted through the laying and compacting step for a certain period of time, for this purpose to cover the surface of the pavement with a curing material. Here, PE film (polyethylene film) may be adopted as the curing material.

After the curing step as described above, when the pavement is hardened, the surface cleansing step is performed, in the surface cleansing step to check the occurrence of cracks and the presence of foreign substances, and to clean the surface of the pavement smoothly.
