IT IS OUR DIFFERENCE THAT MAKES US UNIQUE. Comparison Table for AAC Blocks to Red Clay Bricks Parameters Brik-O-Lite AAC Blocks Burnt Red Clay Bricks 1 Basic raw materials & other inputs Cement IS-12269, IS-8112, Sand/PFA-IS-383,High Quality Lime IS-712,Gypsum,Water-IS-456, Fly Ash-IS-3812(PT-1) & aluminium as aerating compound Top Soil & Energy 2 Dry Density kg/m3 550 - 650 kg/m3(dry oven) IS-2185(PT-3) 1900 kg/m3 3 Compressive Strength in kg/cm3 30-45 kg/cm3, IS-2185(PT-4) 40-75-kg/cm3 4 Aging Gains strength with age No gain in strength with age 5 Thermal Conductivity (W/m-k.) 0.24 W/m.k.(for 551-650 kg/m3) 0.81 W/m.K. 6 Sound Insulation Superior than burnt clay & hollow concrete Normal 7 Ease of Working Can be cut, nailed & drilled Normal 8 Fire Resistance 4 to 6 Hours (depending on thickness) 2 Hours 9 Sound Reducing Index 45 db for 200 mm thick wall 50 db for 230 mm thick wall, for the frequency ranging from 200 to 2000 hz 10 Pest & Rodent Resistance No fungus & algae germination due to non organic properties Algae Susceptible 11 Process Casting-rising-Precuring-IS-456, IS-2185(PT-4) Moulding heat treatment 12 Pre-cast Brick Size 600X200X75 To 300mm-IS-2185(PT-3,4) 230X100X70mm 13 Pre-cast Elements Any size of elements Not feasible 14 Water Absorption % by weight Less than 20% by volume-IS-2185(PT-3) 20% by volume 15 Drying Shrinkage mm/meter Shrinkage after maturing 0.011 (for 600 kg/m3) IS-2815(PT-3) No shrinkage 16 Productivity Output 100% more than brick work Normal 17 Eco Friendliness Pollution free, normal energy requirement, open process uses fly ash or sand lime Creates smoke, uses high energy, wastes agricultural land 18 Structural saving due to dead weight reduction 55% reduction in weight of walls. Tremendous structural saving for high rise buildings in earthquake/poor soil area No additional saving 19 Delivery Pre-Cured and ready for delivery-IS-456 Seasonal 20 Automization Automated manufacturing process-accurate design mix Manual 21 Labour involvement for 10x10 ft wall 1 Labour 2 Labours 22 Construction Speed Very high due to bigger size, light weight Comparatively lower 23 Quality Uniform and finished Normally varies Savings Comparison Of Brik-O-Lite vs Red Clay Bricks PARAMETERS BRIK-O-LITE AAC CONVENTIONAL BRICKS Savings in Steel 15-20 % due to lower dead-weight/load No Saving Savings in Cement 10%-15% No Saving Savings in Mortar 70%-80% reduction in use of Mortar. Less joints results in lesser quantity of mortar for building. No Saving Savings in Plaster 60%-70% reduction in the cost of plastering. AAC blocks have uniforms shape and texture, which gives even surface to the walls. No Saving Savings in Labor 10%-15% saving in Labour cost More Labour required Savings in Operational Cost 25% saving in Operation cost No Saving Savings in Construction Time Installation time 3 to 3.5 times faster. Speedy construction due to big size Slow construction due to small size Savings in Energy Approx 30% Air-condition load, both heating and cooling will come down No Saving Savings in Carpet Area More Carpet area is available in same built-up area due to less thickness of walling – 2%-3% Less carpet area available due to more thickness of walling
