Artificial Lightweight Aggregate

Aggregate is used for the purpose of reducing the weight of concrete and improving a wide range of functions required in the industrial field such as insulation, sound absorption, heat resistance, process ability, economic feasibility. According to the production method, it is classified into natural light-weight aggregate, Busan light aggregate, and artificial light aggregate. SJ produces pumice, tailing and bottom ash.

Artificial Lightweight Aggregate

Low density and higher compressive strength

Artificial Lightweight Aggregate

Severe environmental pollution due to industrial waste generation

Product and Business Overview

Characteristics of artificial lightweight aggregate

Used for the purpose of reducing the weight and improving a wide range of functions required in the industrial field such as insulation, sound absorption, heat resistance, process ability, and
economic feasibility

Insulation and fire resistance

Better insulation and fire resistance than ordinary aggregate

Lower Density

50-500% lighter than
ordinary aggregate

Excellent sound absorption

Excellent sound insulation effect than ordinary aggregate

Compressive strength

Higher compressive strength than natural lightweight aggregate

Excellent antibacterial effect

Prevents atopy and has excellent antibacterial effects

Cross section reduction

Thinner than ordinary concrete

High Strength

2-3 times higher strength than
normal cement

Seismic performance

Applicable to the seismic design of structures

Application

Concrete-structural

Main demand field of artificial lightweight aggregate
Slab for Skyscraper superstructure
Reduce construction cost

Concrete-non structural

A secondary product used as a lightweight panel, and sound insulation material
Cost reduction due to physical properties, sound absorption and fire resistance

Civil engineering

Used in various civil engineering fields such as bridge decks, bridge piers, roadbeds, road paving

Water purification

Providing the best environment for microorgan- isms to live, including high strength advantages of common rocks and good surface area
Demand of current domestic redundant member market for imported goods

Heavy water reactor

Easy for microorganisms to live such as internal space and superior penetration of artificial lightweight aggregate
Excellent in initial rainwater treatment and used in heavy water reactors because of the advantages of securing water resources

Petrochemistry

Low weight contributes to weight reduction in distillation columns
Soil reinforcement technology contributes to stabilization of the ground
Excellent weight reduction effect for offshore
concrete structures
