Description

[0001] Construction material composition comprising pine nuts [0002]

An environmentally friendly building material composition is disclosed herein.

Pine nuts are the fruit of the pine tree and are known to be either non-baked foods or fresh foods, and are one of the nuts most popular for their abundant nutrition and taste. According to the Ministry of Agriculture and Forestry statistics, 2,680 tons of pine nuts are produced in Korea in 2005. However, pine nuts are used only for pine nuts after harvest. Therefore, byproducts other than pine nuts are discarded as they are left as environmental pollutants, and some of them are used as firewood, but their degree is small. Therefore, it is necessary to study the effective recycling method of pine nuts.

On the other hand, in the case of roads packed with asphalt or cement, there is the aspect that it meets the strength required for the road and it is convenient for maintenance. However, the rocks, There is a limitation in that it gives an emotionally stale feeling and causes discomfort due to the released harmful components.

Asphalt and cement are non-eco-friendly construction materials. When people use the asphalt or cement trails to exercise or walk for health maintenance and relaxation, the walking impact of people walking and walking is transmitted to the joints and backs. The use of such building materials is also a health hazard. Furthermore, in the case of construction materials used in the past, in particular concrete, environmental problems are caused by damaging the natural environment in the process of securing the landfill, and some of the waste concrete is buried or dumped without permission.

Accordingly, in recent years, there has been a lot of efforts to construct a walkway, a playground, and building interior / exterior materials utilizing environmentally friendly materials. Typically, there is a building material made using loess, which is often insufficient to substitute for existing building materials because the construction material is severely damaged by drying shrinkage and rainwater. In addition, most of the emerging construction materials, which are eco-friendly, require a large amount of artificial coloring matter because they are based on dark aggregates and cement. Therefore, a vicious cycle in which more cement than ordinary concrete is used Is repeated. In particular, the construction material by the above method has a problem that it is easily damaged by rain or sunlight.

Accordingly, the present inventors have conducted studies to produce building materials having excellent compressive strength, bending strength and water absorption ratio as compared with road pavement materials using cement while having environment friendliness, and have found that by using pine nut except for nutshell, And the present invention has been completed.
