The ocher ball mortar of the present invention is made by mixing the ocher ball and cement and water made by calcining the ocher to 600 ~ 1200 ℃ can be used immediately in the field. The mixing ratio of cement and ocher balls is suitable from 1: 3 to 1: 4.5, and the mixing water is 25-30% of the combined weight of cement and ocher balls. The loess mortar of the present invention can be used as a finishing material of the floor and walls of the building because it is very solid and excellent adhesion. It is very good for health because it has good absorbency and breathability and neutralizes the toxicity of cement.

Description

Manufacture of the loess ball mortar}

The present invention relates to the production of ocher ball mortar, the object of the present invention is to make a mortar that has a high water absorption rate and breathability, good for health, can be easily manufactured at the construction site.

Ocher is known to be very good for health by emitting far infrared rays as well as its ability to control humidity, heat storage, heat insulation, breathability, deodorizing effect, antibacterial effect, and harmful gas due to absorbency and hygroscopicity. Therefore, loess has been used for a long time as building materials such as high-rise walls, floors, kitchen arches, ceramic raw materials such as red bricks, earthenware, roof tiles, soil improvers, fish farm floors, barns, etc. It is used for building materials such as wall materials, cosmetics, ocher jjimjilbang, ocher bed, medicine, and red tide removal.

In particular, many ocher mortars have been developed for finishing floors and walls of high-end apartments, all of which are made by mixing various inorganic and organic materials with ocher powder. According to the Republic of Korea Patent Publication (B1) registration No. 10-0230569, the high-mobility ocher mortar is a loess binder consisting of ocher, pozzolanic, quicklime, swelling agent, sand and water, polycarboxylic acid and naphthalin, polyol derivatives, melamine, It is made by mixing organic materials such as aminosulfonic acid, and used as floor finishing material for ondol room for hot water heating. It is made by mixing various inorganic materials and organic materials. Complex and organic materials may have harmful effects on the human body. Might hurt. According to Korean Laid-open Patent Publication (A) Publication No. 2001-0054071, Plastering ocher mortar is prepared by mixing powder vegetable adhesive with ocher and applying an aesthetic material to give texture and gloss after plastering, There is a drawback that the beauty of the lodge blocks the pores of the loess and loses all the inherent characteristics of the loess. According to Korean Patent Laid-Open Publication No. 1999-0031507, the method for preparing ocher mortar cracking agent is made by mixing an aqueous solution of chromic acid alumina, hydrated silicon silica, and acrylic ester with ocher, which is complicated to use in construction sites. Do. According to Published Patent Publication (A) Publication No. 10-2001-0038156, the admixture for preventing cracking ocher mortar and its manufacturing method are suitable mixture ratios of blast furnace slag, limestone, gypsum and hydrated lime at an appropriate blending ratio. It is a complicated method to make a mixture of admixture and ocher mortar. According to Korean Patent Laid-Open Publication No. 2001-0089914, non-condensing high-strength ocher mortar that emits far infrared rays is made of potassium aluminate expansion hardener, gypsum, and aggregate in loess. According to the Republic of Korea Utility Model Publication (A) No. 1998-019640, the crack-resistant ocher motor is made by combining the swelling agent, sand, textile material, water mixture, water reducing agent in the loess. According to the Republic of Korea Patent Publication (B1) No. 10-0245469, the self-leveling ocher mortar composition for buildings is made of admixture that is a high-performance susceptor for ocher, lime, aggregate, naphthalene-based high-condensate.

As mentioned above, ocher mortar is made by mixing various inorganic and organic materials with ocher powder, which is inconvenient to use immediately in the construction site due to complicated process.

Therefore, in order to solve this problem, it was succeeded to make the ocher ball mortar by mixing the ocher ball and cement made by baking the ocher at 600 ~ 1200 ℃ and kneading with water. It is very simple to use, so anyone can use it easily at the construction site, and the characteristics of the loess are still intact.

The present invention is to make a loess ball mortar by mixing a small bead-shaped ocher ball and cement made by baking the loess at 600 ~ 1200 ℃ and kneading with water, the weight ratio of cement and ocher ball is 1: 3 to 1: 4.5 The degree is appropriate, and the mixing water is suitable for 25 to 30% of the combined weight of cement and ocher balls. When the mixture weight ratio of cement and ocher balls is less than 1: 3, the ocher ball mortar is applied to the wall or floor and dried to cause cracking. When the compounding weight ratio of cement and ocher ball is 1: 3 or more, the higher the compounding weight ratio is, the more beautiful the surface shows the color of ocher. When the mixture weight ratio of cement and ocher balls is 1: 4.5 or more, it is difficult to apply the ocher ball mortar because of its compressive strength and adhesion to walls.

Hereinafter, a method of manufacturing the ocher ball mortar according to the present invention will be described with examples.

<Example>

Cement and ocher balls are mixed in a weight ratio of 1: 2, 1: 2.5, 1: 3, 1: 3.5, and 1: 4 respectively. After 28 days, compressive strength test, water absorption rate measurement, specific gravity measurement, and surface crack test were obtained.

Looking at the table above, we can see that: The optimum weight ratio of the blended water to the combined weight of cement and ocher balls is 27-30%. The compressive strength is 139 ~ 303kg / ㎠, and when cement and standard sand are mixed in a weight ratio of 1: 2.45, when the age is 28 days, the KS standard compressive strength of ordinary portland cement mortar is slightly lower than 290kg / ㎠ However, it is thought that the ocher ball mortar has sufficient strength to be used as the mortar on the floor and inner wall of the house. The water absorption rate is 19-24%. As the weight ratio of the ocher balls to cement increases, the water absorption rate increases slightly. The specific gravity is 1.56-1.64 g / cm 3 and it can be seen that the weight ratio of the ocher balls to cement becomes somewhat smaller. Importantly, when the ocher ball mortar was widely applied on the concrete surface and the surface crack was examined after 28 days, the weight ratio of cement and loess should not be more than 1: 3.

The ocher mortar has been developed so far that it is inconvenient to use by adding various inorganic and organic materials to the ocher powder, so it is inconvenient for workers to use it.However, the ocher ball mortar of the present invention is made of cement, ocher ball, Water can be used in combination. In addition, the compressive strength of the specimen made of ocher ball mortar is also large and can be used on the inner wall and floor of the building, and the ocher ball mortar component neutralizes the cement poison and is very good for human health.
