Description

Construction material composition comprising pine nuts shell}

Disclosed herein are environmentally friendly building materials compositions.

Pine nut is a fruit of pine tree, and it is known as a food of firewood or fresh food since ancient times. It is one of the nuts loved by many people because of its rich nutrition and savory taste. According to the Ministry of Agriculture and Forestry, 2,680 tons of pine nuts are produced in Korea in 2005. However, pine nuts are only used for food after harvest. Therefore, by-products other than pine kernels are discarded as it is, and left as an environmental pollution source, and some of them are used as a firewood, but the degree is insignificant, and research on an effective method of recycling pine nuts is required.

On the other hand, in the case of roads paved with asphalt or cement, there is a side that satisfies the strength required for the road and there is convenience in maintenance. There is a limit to feeling emotionally depressed and causing discomfort due to the harmful substances emitted.

Asphalt or cement are non-eco-friendly building materials.If the construction of asphalt or cement is used to build a walking or walking trail for people's health and rest, the walking impact of the walking and walking people will be transmitted to the joints or waist. The use of the building material may be a health hazard. Furthermore, in the case of the existing building materials, especially concrete, in the process of securing a landfill site, the natural environment is damaged, and some of the waste concrete is causing environmental problems such as unauthorized landfilling or dumping.

Accordingly, in recent years, there has been an active movement to construct walkways, playgrounds, and interior and exterior materials using environmentally friendly materials. Representatively, there is a building material manufactured using loess, and the building material is severely damaged by rainwater due to severe drying contraction and is insufficient to replace the existing building material. In addition, most of the building materials appearing in an eco-friendly way are based on dark aggregates and cements, and therefore require a large amount of artificial pigments, and due to the degradation of the building materials, more cement is used than normal concrete. This is being repeated. In particular, the building material according to the above method has a problem that is easily damaged by rain or sunlight.

Thus, the inventors conducted environmental studies to produce building materials having excellent compressive strength, flexural strength, and absorption rate compared to road paving materials using cement, and excellent construction materials using pine bark except pine kernels. It was confirmed that can be prepared and completed the present invention.
