Description

COMPOSITION OF HYDRAULIC MORTAR USING YELLOW SOIL AND SLAG AND PRODUCING METHOD THEREOF

The present invention relates to mortar and in particular to a mortar for finishing the walls or floors of buildings as hydraulic mortar using ocher and slag.

Ocher is a honeycomb structure with a large surface, and a large number of spaces make up a multi-layer structure. In the sponge-like hole formed by the multi-layer structure, far infrared rays are absorbed and stored in large amounts, releasing when heated and stimulate the rich activity of other objects.

And, ocher radiates beneficial far infrared rays to human body, and thus the absorbed far infrared rays are absorbed by the human body, so metabolism is good and activates blood circulation to activate cell activity, thus preventing aging, promoting metabolism, and chronic It is already widely known that it is effective in preventing various diseases such as fatigue.

In order to construct the walls or floors of the building using the known loess, the cement, which occupies most of the modern buildings, contains alkaline ingredients that are harmful to the human body. By constructing the floor, it was used to provide a pleasant living space in our residential environment by removing odors with the excellent adsorption power of ocher and suppressing the growth of bacteria such as molds with excellent antibacterial activity.

In many cases, yellow blocks were used to make building blocks and panels, and to use them for furniture such as beds.

In order to use it as a mortar for construction as such ocher, so far, it has been possible to increase the bonding strength by mixing ocher and cement, but since the cement is mixed, it contains an alkaline ingredient harmful to the human body, which is harmful to the human body.

In order to solve these problems, in order not to be harmful to the human body, only the sand was mixed with loess to make mortar, which caused problems such as bubbles and cracks on the surface after construction.

The present invention has been invented in view of the above-mentioned problems, and prevents the formation of bubbles and cracks on the surface after construction, and also uses the industrial waste slag as a curing agent to prevent the problem of polluting the natural environment caused by industrial waste. By using fly ash or blast furnace slag as a hardening material, it is possible to save drying energy by the heat of combustion generated when unreacted hydrocarbon of fly ash is burned during drying, and bubbles and cracks are generated on the surface by using antifoaming agent and resin. To prevent the surface finish.

Referring to the composition of the hydraulic mortar using the loess and slag of the present invention in detail.

Hardener 10-25% of yellow soil 50-60 dried at 40 ° C and ground to 40-60 mesh, 15-20% by weight of sand, and fly ash or blast furnace slag generated in the converter to remove sterilization and moisture. 2% by weight, 2-5% by weight of antifoaming agent to prevent bubbles from forming on the surface after construction, 10-25% by weight of gypsum as curing agent, and 2-5% by weight of resin to prevent surface cracking after construction And, it consists of 5-7% by weight of activated carbon for dehumidification and deodorization.

Hereinafter, a method for preparing mortar comprising the composition will be described in detail.

The first drying process of drying the ocher and the fly ash or slag hardener made by removing the foreign matter such as gravel by the sorting machine at 600 ° C. by the dryer, and the ocher and the curing agent dried in the first drying process by the grinder 40 And a second drying step of removing the foreign matter from the sand, which is aggregated in the state of being stored in the cyclone, and then drying the powder pulverized in the grinding process at -60 mesh to 600 ° C. by a dryer. It consists of a process of mixing the crushed ocher powder and the sand dried by the second drying process, the antifoaming agent, gypsum and the resin.

Hereinafter, an embodiment of the present invention will be described in detail.

The collected loess usually contains 20% moisture, and the gravel or other foreign matter contained in the loess is sorted by a sorter.

The selected ocher and the curing agent fly ash and blast furnace slag are dried at 600 ° C. by a dryer, and the dried ocher prevents mold from occurring on the surface after construction due to sterilization and moisture removal and prevents natural hardening. To do that.

In addition, unreacted hydrocarbons of the fly ash are burned in a dry fixation, whereby drying energy can be reduced by the heat of combustion.

Thus dried loess and hardener are pulverized into a 40-60 mesh by a crusher is transported to the cyclone and stored.

At this time, in the other line, the foreign matter is removed and the sand which is the selected aggregate is dried by a dryer.

The aggregate and hardener thus dried are transported and stored in a cyclo.

Thus, in the state of being stored in the ocher powder and aggregate and cyclo, 50 to 60% by weight of ocher, 15 to 20% by weight of aggregate, 10 to 25% by weight of hardener, 2 to 5% by weight of antifoam, and 10 to 25% by weight of gypsum %, 2 to 5% by weight of resin, and 5 to 7% by weight of activated carbon are mixed by a mixer.

The composition formed by mixing in this way becomes mortar when mixed with water.

Such mortar can be used as a wall finishing or floor finishing agent of the building, it can also be used as a mortar used as a finishing agent for finishing the floor surface of furniture such as beds.

Since the mortar formed in this way does not contain cement as in the prior art, it can remove harmful elements to the human body and also smooth out the finished wall or floor surface by preventing bubbles or cracks on the surface after construction. It is a useful invention.
