Description

Packaging with earth and recycled concrete {Pavement with earth and recycled concrete}

The present invention relates to a packaging material using soil and waste concrete.

Waste concrete waste, which is generated in large quantities every year, damages nature during landfilling, and the collection of rocks, gravel, and sand, which are raw materials of aggregates, also causes damage to nature. Some of the waste concrete is even landfilled or dumped, causing pollution to the environment. Therefore, by using the aggregate recycled waste concrete, it is possible to reduce the natural damage caused by the collection of aggregate or the landfill of construction waste and to reduce the pollution of the environment due to the disposal of illegal waste.

In addition, when the soil is used as a packaging material, the cost can be reduced, and the color of the soil is reflected in the color of the packaging material, which can provide emotional stability, and can also help maintain health through far-infrared rays emitted from the soil. . Therefore, various techniques for using the soil as a packaging material have been developed.

As a technology for paving materials using soil, Korean Patent Registration No. 10-0408594 Ocher road paving material and its manufacturing method mix the clay powder and cement which are baked and crushed to 100-150mesh at a weight ratio of 0.75-1.42: 1, Road paving material mixed with sand and water was provided.

The present invention provides a packaging material exhibiting excellent quality without requiring complicated processing in using soil.

In the present invention, environmentally friendly packaging materials that can reduce the damage to nature due to the collection of aggregates or landfill of construction waste, reduce the pollution of the environment due to the disposal of illegal waste, reduce the cost and improve the health of far-infrared radiation To provide.

The present invention relates to a packaging material using soil and recycled aggregates, and includes recycled aggregates, soil, cement, waterproof admixtures, and water.

The recycled aggregate is manufactured by crushing the waste concrete in a jaw crusher, passing through the aggregate sorter, sorting it, and then removing foreign substances using a blower. The manufactured recycled aggregate is sifted and coarse aggregate of 25mm or less. Separated into fine aggregate of 8mm and less.

Soil is used to collect high quality soil that does not contain foreign substances such as stones or various wastes. If it contains a large amount of water, the strength of the packaging material may fall, so the moisture content of the soil is preferably about 10% by weight, and if necessary, prepare through a natural drying process. In addition, even if the size of the particles is too large, the quality of the packaging material may be deteriorated, it is preferable to use the crushed to a particle size of about 100 mesh. Including soil in the packaging material not only reduces the cost, but also gives the emotional stability by showing the color similar to the natural environment in the color of the packaging material, and can also help maintain health through far-infrared rays emitted from the soil. . If the mixing amount of the soil is less than the above effect, if the mixing amount is too much, there is a disadvantage that the strength of the packaging material falls, in the present invention, it is mixed to 20 to 40% by weight.

Cement generally uses one or two types of portland cement, but there is no restriction on the types of specially available cements. For emergency repairs that require high strength in a short period of time, cemented steel cement or alumina cement can be used. Cement etc. can also be used. If the cement content is low, the strength is low, if the content is too high, flexibility is poor, in the present invention, 10% by weight of cement is mixed.

Waterproof admixtures increase the basic strength of concrete structures by preventing water permeation. Generally, oil-based or polymer-based materials affect the permeability of concrete by the waterproofness of the material itself. It is known to exhibit an effect by changing the density. In the present invention, as a waterproof admixture, a conmix (Handong Regeneration Corporation, Korea) product manufactured and sold by synthesizing from a water-soluble salt of polycarboxylic acid and an extract monomer of petroleum naphtha is used. The waterproof admixture is used to prepare a waterproof admixture by diluting it to a concentration of 8% by weight in water for convenience of mixing. When the content of the waterproof admixture is low, the effect of waterproofing and strength increase is reduced, and the content is too high. The water and admixture weaken the bonding strength of the concrete, rather the strength is lowered, so mix to 5% by weight of the total packaging material.

The packaging material of the present invention is composed of 45 to 65% by weight of circulating aggregate, 20 to 40% by weight, 10% by weight of cement, 5% by weight of waterproof admixture, and the waterproof admixture is composed of 92% by weight of waterproof admixture of 8% by weight. Consists of% water.

EXAMPLE

Dilute the waterproof admixture (Conmix, Handong Regeneration) in water at a concentration of 8% by weight to make a waterproof admixture, prepare coarse aggregates of 25mm or less, fine aggregates of 8mm or less, fine aggregates of 100 mesh in size, and cement of Portland. It was. The packaging materials 1 to 3 according to the following Table 1 was formulated and laid on the road and samples were taken one week later.
