Bata Ringan
BUILDING MATERIALS & CONSTRUCTIONbeginner
Definition
Lightweight concrete block — similar to batako but with reduced density (typically 600–1000 kg/m³) achieved by incorporating expanded clay, pumice, or foam. Bata ringan provides superior insulation and is easier to cut and handle than batako. It is preferred in high-rise construction to reduce structural loads and in thermal-conscious residential design.
Example
The Graha Citra tower in Jakarta (2000s) uses bata ringan for all partition walls — the lightweight blocks reducing the total structural load, allowing a more efficient structural frame and lower material and energy costs compared to traditional masonry.
