KR20000072274A - Forming method of porous lava stone concrete - Google Patents

Abstract

PURPOSE: A method of shaping a concrete in the form of porous lava stone is provided, which can impart the feeling of a natural rock to a concrete shaped article by forming myriad porosities on the exposed surface of the concrete shaped article. CONSTITUTION: A method of shaping comprises the steps of : mixing fine stone powder, cement mortar, crushed styrofoam particles, and the coloring water containing a rock color; feeding the mixture to a mold and solidifying the mixture; separating the solidified concrete shaped article from the mold and removing the mortar film on the surface layer of the shaped article to expose the incorporated styrofoam particles; coating a dissolving agent on the exposed particles to form myriad porosity in the exterior layer of the shaped article.

Description

Porous Lava Forms Concrete Forming Method {.}

The present invention is a concrete molding method in which the characteristic natural form of natural porous lava stone is implemented similarly in appearance by combining the present method with the existing concrete method, and the method is made through a simple process that can be easily implemented.

In other words, a cement is added to the cement mortar mixed with the crushed styrofoam particles and solidified by a model frame to form a concrete model and then dissolve the styrofoam particles scattered on the object.

By doing so, it is possible to create a form similar to natural porous lava stone, thereby providing electricity to compensate for the unrealistic part.

In reality, there is a limit to the supply of natural rock resources, and inevitably, countermeasures are inevitable in order to meet the infinite demand.

Therefore, it is a handicap of natural rock because it takes a lot of burden to commercialize natural materials.

Therefore, by using the molding method according to the present invention, it is possible to easily create quantities and shapes with a small burden, as well as to be applied to the fields of landscaping, building decoration materials, various stone shapes, etc., taking advantage of the ability to produce a variety of natural images. It will be the basis to activate the harmony between living environment and nature.

Process diagram

In order to form porous lava-shaped concrete, fine stone powder, cement, and crushed styrofoam particles, which are the main components, are prepared in a ratio of 1: 2: 3. You also need colored water to agitate these ingredients.

Adding color to the water is to express the color of the rock in the concrete model.

The prepared materials are added to the stirring vessel at the same time and stirred in a thin dough.

After the stirring, the mortar is poured into the prepared mold, and it is solidified by compacting so as not to leave a void.

Care should be taken to maintain the appropriate hardness as the hardness of solidification affects the following processes.

The solidified concrete form is dismantled and separated from the mold.

At this time, the surface of the concrete model body is a state in which a coalesced film of mortar is formed and the styrofoam particles scattered in the entire area of the concrete object are in a state of being removed.

In order to remove the film, it is necessary to select a work tool according to the hardness of concrete, but in most cases, brushing with an iron brush can remove the film without difficulty.

When the coating is removed, the styrofoam particles scattered from the subcutaneous layer are exposed.

The next step is to apply the solvent to the entire area of the object where the Styrofoam is exposed.

As the styrofoam particles contained in the concrete tissue are dissolved, the cavitation state is changed and the entire surface area is transformed into the porous cortex.

The present invention can be duplicated by the model frame, so that the production effect can be maximized, as well as the natural aesthetic appearance, which is inferior to natural stone, and the durability of concrete is considered to be semipermanent in terms of durability. Is enough.

In particular, it is considered to be highly preferred because it is similar to the form of natural porous lava that is rare, and its visual response is different compared to generalized rocks. In that sense, you can get another effect.
