The present invention relates to a method of manufacturing a water-permeable interlocking block, and more particularly, water permeability by using recycled aggregate separated from waste concrete and solidified charcoal crushed material to maximize waste recycling. The present invention relates to a method for manufacturing an interlocking block having a plurality of storage spaces capable of maximizing and storing water permeated in a block.

Reinforced concrete structures, which began to increase with industrial development, are dismantled by projects such as urban redevelopment or urban environment maintenance, and are rapidly increasing construction waste.

These construction wastes are simply landfilled in the disposal method, and require a new landfill site, but the site selection and environmental pollution are a big problem when landfilling.

It is well known that, as a counter-concept, research on the regeneration of construction waste causing environmental pollution and applying it to various fields is also active at the same time. The Act on the Promotion of Effective Use of Resources and the Construction Recycling Act "Is enacted.

As well-known examples, Korean Patent Application No. 2001-15124 "Method for manufacturing water purification concrete using industrial by-products" and Korean Patent Application No. 2002- 57418 "Environmentally Friendly Concrete for Water Purification Using Recycled Aggregates" has been disclosed and uses industrial waste products or waste concrete, which are construction wastes.

The above known examples have been attracting attention by simultaneously purifying water quality by forming excellent porosity within 13% to 40% at the same time, but it was insufficient to neutralize various impurities generated from recycled aggregates or waste concrete.

In addition, as another well-known example, Korean Patent Application No. 2000-69179 "Manufacturing method of environmentally friendly high-performance aggregate viscous continuous void-absorbing concrete using recycled aggregates and new materials" is disclosed using construction wastes. By providing phosphorus concrete, construction waste is recycled and the recycling is maximized.

However, the other well-known examples are limited to sound absorption only, and can be used only to clean water quality or to recycle only simple building materials that cannot release functional materials such as anions and applied to sidewalk blocks or indoor road paving. There was room for it.

As another known example, Korean Patent Application No. 2001-29295 "Ocher Concrete Composition" and Korean Patent Application No. 2003- for providing concrete composition using artificial reef, block or loess using recycled aggregate which is construction waste No. 18962 "Concrete composition including recycled aggregate and artificial reef manufactured by the concrete composition", Korean Patent Application No. 2004-68179 "Manufacturing method of multifunctional environment block for constructing using recycled aggregate and industrial by-product", Korean patent Application No. 2005-24650 discloses a composition for concrete admixture using industrial waste, concrete composition and concrete structure comprising the same.

However, the other known examples as described above are intended for the purpose of the application of recycling resources or increasing the strength of concrete.
