Autoclaved Aerated Concrete [AAC] Block

Autoclaved Aerated Concrete (AAC) is a lightweight concrete building material cut into masonry blocks or formed larger planks and panels. Aerated concrete is relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase, yet shows vast variation in its properties. The properties of aerated concrete depend on its microstructure (void± paste system) and composition, which are influenced by the type of binder used, methods of pore- formation and curing. Although aerated concrete was initially envisaged as a good insulation material, there has been renewed interest in its structural characteristics in view of its lighter weight, savings in material and potential for large scale utilization of wastes like pulverized fuel ash. Many researchers have been done in the last few years however a deeper understanding is still needed to improve the quality of autoclaved aerated block in the construction industry by studying the current market behavior. The aim of this study is to get the latest information and to identify the key factors that affect on autoclaved aerated block. Data’s are collected through questionnaires and distributed to respondents who work on various projects in wide areas in the charotar region of central Gujarat. Respondents were required to rate and analyze using their experience and the factors were identified from past researches, which affects the project performance and then the level is measured based on their effect. The data collected are analyzed using Microsoft Excel or Statistical Package for the Social Sciences (SPSS Statistics 17.0) software which is analytical software.
