Manufacturing method for ground paving materials using bottom ash

Abstract

The invention relates to a manufacturing method for ground paving materials including bottom ash using a forming device, the materials being environmental-friendly and having water permeability and compression strength and durability. The forming device includes a primary mortar supply part, a secondary mortar supply part, a tertiary mortar supply part, and a forming part including a pressing unit. The method includes: a mixture supply step of supplying a mortar mixture, including bottom ash having different particle sizes, to each of the primary to tertiary mortar supply parts; a primary mortar discharge step of discharging a mixture of the primary mortar supply part; a secondary mortar discharge step of discharging a mixture of the secondary mortar supply part to stack the mixture on themixture of the primary mortar supply part; a tertiary mortar discharge step of discharging a mixture of the tertiary mortar supply part to stack the mixture on the mixtures of the primary and secondary mortar supply parts; and a forming step of pressing the mixtures of the primary, secondary, and tertiary mortar supply parts into the mold through the pressing unit of the forming part.

Description

technical field [0001] The present invention relates to a method of manufacturing floor covering materials using bottom ash, and more specifically relates to manufacturing floor coverings using a molding device including a mechanism capable of supplying three types of mortar and a pressurizing mechanism capable of pressurizing a mold. A method of manufacturing a floor covering material using bottom ash, which contains bottom ash in the material mixture and has a three-stage internal structure, is environmentally friendly, and has water permeability, compressive strength, and durability. Background technique [0002] Driveways paved with asphalt or concrete or sidewalks paved with ordinary floor tiles, because rainwater does not penetrate into the ground, not only cause water seepage disasters, but also distort the city's water circulation system and cause various environmental problems. Specifically, there are problems of non-point source pollution of initial rainwater cause...

AI Technical Summary

Problems solved by technology

[0007] However, permeable floor tiles, which are conventional water-permeable floor covering materials, have a problem of poor durability due to the need to have a porous structure.

This shows that there is a technical limit to replacing asphalt roads with permeable floor tiles as a water-permeable floor covering, that is, the following dilemma occurs: if the strength is increased for permeable floor tiles as a water-permeable floor covering, the porosity decreases While the water permeability is reduced, if the strength is reduced, the porosity increases but cannot bear the load
