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
