CASE STUDY:AERATED CONCRETE

LIGHT|STR0NG|ADVANCED

Submitted by: Kholia Chajiinamei Zoya Matin B.ARCH Vth SEM ASAP, AUR

INTRODUCTION

• Developed in Sweden combining Wood and concrete.• Is a Green Building material with benefits like high

strength to weight ratio, high thermal and sound insulation.

• Easy workability, Low carbon footprint during application and manufacturing etc is said to revolutionize the construction industry in India.

How is it made?

• Lime (8-10%), Gypsum(4-5%), Fly Ash(60%), Cement(25%), Aluminium(0.08%)

• Release of CO2• Saves Steel(15-18%) • No seepage problem• 1 m3 bricks = 1 to 1half bag cement; 1 m3 AAC bricks = half bag cement

FEATURES• Fast and Easy Construction

Big & Accurate sizeLightweight

Excellent Workability

• Energy Efficient & comfortable livingHigh Thermal Insulation

Good Sound Absorption

• Safe LivingFire ResistantHigh Earthquake resistanceWater BarrierPest Resistant

GREEN BUILDING MATERIAL• Least consumption of energy• Utilization of waste materials• Reduction of fuel and CO2 emissions• Reduction of green house gas

emissions and air conditioning requirements
