In the Development of construction materials Sustainable use of natural resources has become a necessity in India. In this project work, an LCA study is carry out for an AAC block production for environmental assessment. In addition to the LCA, the Life Cycle Cost (LCC) analysis is also applied for economic assessment. The LCA is performed according to ISO 14040. Firstly, a cradle to gate LCA method performed for one meter cube of Autoclaved Aerated Concrete Block. The LCCA method include in the OpenLCA software which is choose to calculate impact categories i.e. abiotic depletion, global warming potential, acidification potential, eutrophication potential, Eco toxicity, ozone depletion potential and photochemical oxidation potential. The last few decades, several approaches have been developed by agencies and institutions for Bricks Life Cycle Cost Analysis (LCCA). The LCC analysis was performed by developing a price model for internal and external cost categories within the software.

Non-linear analysis of autoclaved aerated concrete (AAC) block masonry composite wall with column has been conducted using finite element software ABAQUS. First, the finite element results were verified with laboratory results of full-scale specimens. Effects of horizontal reinforcement ratio on seismic performance were investigated. The analysis indicates that shearing strength of the wall is affected by the openings greatly. Seismic performance is improved with the increase of horizontal reinforcement ratio. The effect of vertical stress on wall without openings is more than that on wall with openings. Bearing capacity of walls without openings has a linear relationship with the horizontal reinforcement ratio. And bearing capacity of walls with openings is related to the place where the reinforcements are installed as well as the horizontal reinforcement ratio.

Fluidized fly ash has different physical and chemical properties compared to fly ash emerging from classic combustion. It contains amorphous phases resulting from a dehydration of clay minerals as well as unreacted sorbent of CaCO3, free CaO and anhydrite (CaSO4). Work targets the possibilities of production of an autoclaved aerated concrete (AAC) from fluidized fly ash, and its influence on particular physical-mechanical properties of autoclaved aerated concrete.

Aerated Concrete

Nowadays, the type of foamed concrete performs a group of cemented composite materials that can compete with conventionally used autoclaved aerated concrete. Improving microstructure of the foamed concrete by inventive mixing technology allows to homogenizate the mix of foamed concrete. This original research is applied to inspection on mixing technology of foamed concrete by using a planetary ball mill. The objective of this paper is to clarify the correlation between physical-mechanical properties and intensive mixing time.
