PRODUCE METHOD OF LIGHTWEIGHT AGGREGATE FOR LIGHTWEIGHT AGGREGATE CONCRETE

摘要

The present invention is processed clay and deciduous leaves, food waste, sawdust, rice straw, etc. according to the mixing ratio as clay mineral sludge and natural general soil and organic materials generated when processing and washing the raw stone collected from various underground trench construction and river sites After the mixing process mixed with the kneader and the wet injection method, molding, drying, pulverizing, and storing process, the finely divided material of 0.074mm or less is formed into a spherical body by spraying water droplets with a rotating plate molding machine to prevent the bonding during firing. Spheroid molding process to apply limestone kaolin paper sludge, etc. to somewhat high refractory inorganic materials, and high temperature firing process to reduce the specific gravity to 0.5 ~ 0.8 as the spherical body expands by firing with 1020 ~ 1200 ℃ rotary kill Environmental pollution by providing artificial lightweight aggregate using organic and inorganic materials that are disposed of When it is used in concrete, it is a method of manufacturing ultra-lightweight artificial aggregates that can be made of light concrete while keeping the compressive strength at a comparable level with less density than natural aggregates.
