Brikolite AAC blocks are lightweight, cement-based, steam-cured blocks made with fly ash, lime, cement, gypsum and aluminium as the aerating compound in a 100% automatic plant with German technology (Lohia Group / KD Infra, Assam). Oven-dry density is 550-650 kg/m3. The brochure recommends minimum 125 mm wall thickness for internal and 150 mm for external walls and lists approved use in government, institutional and commercial projects across North East India.

Key features

• Lightweight
• reduces dead weight and steel consumption
• High compressive strength from high-pressure steam curing
• Can be cut, grooved, nailed, drilled and chased with simple tools
• Faster construction
• lighter blocks and less setting time
• Qualifies for LEED/GRIHA green building points
• fly-ash based
• Meets seismic Zone IV and V requirement (as stated)
• Fire resistant
• pest and termite resistant (inorganic)
• Acoustic insulation
• STC-44 class (as stated)
• Premix thin-bed mortar joint of 3-4 mm vs conventional 10-12 mm

Applications

• Internal walls (min. 125 mm thickness recommended)
• External walls (min. 150 mm thickness recommended)
• Green buildings
• Buildings in seismic Zones IV and V
