Hollow Blocks vs Autoclaved Lightweight Concrete (ALC) Wall Panels
Hollow Blocks ALC Wall Panels
Feature Hollow Blocks Autoclaved Lightweight Concrete (ALC) Wall Panels
Material Composition Cement, aggregate (sand or gravel), water Fine aggregates, cement, lime, gypsum, aluminum powder, water
Manufacturing Process Molded and cured by air drying or steam curing Mixture poured into molds, then autoclaved (high pressure & temperature)
Physical Characteristics Rectangular with hollow cores Lightweight, solid with uniform fine texture
Standard Sizes Varies, but standardized for uniformity Large, prefabricated panels
Weight Heavier Lightweight
Thermal Insulation Good (due to hollow cores) Excellent (high thermal insulation properties)
Sound Insulation Good Excellent
Fire Resistance Moderate High
Moisture Resistance Moderate High
Applications Walls, foundations, structural elements Load-bearing and non-load-bearing walls, partitions
Construction Speed Moderate Fast (due to prefabrication)
Cost Cost-effective More expensive
Handling and Installation Easy to work with and modify on-site Requires specialized handling and installation techniques
Surface Finish Often requires additional finishing (plaster/paint) Smooth surface, less need for finishing
Availability Widely available Limited in some regions
Environmental Impact Moderate Generally lower due to better insulation and reduced weight
