COST EFFECTIVENESS OF USING AAC BLOCKS FOR BUILDING CONSTRUCTION IN RESIDENTIAL BUILDING AND PUBLIC BUILDINGS

Abstract

Red bricks are one of the most pre-eminant construction material used for construction. The carbon dioxide emissions in the brick manufacturing process has been certified as a relevant factor to global warming. Therefore, it becomes necessary to focus more on pursuing environmental solutions for greener environment. To fulfill this objective, new construction materials can be used for construction. One such material i.e., AAC blocks can be used as an alternative material for construction. This paper highlights the comparative statistical analysis of cost effectiveness of using AAC blocks instead of traditional red bricks. The use of AAC blocks gives an eventual solution to the construction industry about the environmental related issues. In this study, an attempt has been made to replace the burnt clay red bricks with the autoclave aerated concrete blocks. The different types of tests were performed to determine various properties of AAC blocks as compared to others. The 6” and 9” thick wall building were designed using Staad pro software and the cost calculation for different component parts of the building were carried out. From the experimental results, it is observed that the compressive strength of AAC block is comparatively more than traditional bricks and the density of AAC block is comparatively less which helps in reducing the dead load of structure. It is found that upto 15 to 20% , the cost of construction can be reduced by using AAC blocks.
