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.

The phase change energy storage aggregate was prepared with the eutectic mixture of capric acid (CA) and stearic acid (SA) as phase change energy storage material (PCM) and waste autoclaved aerated concrete as skeleton. The results showed that the appropriate mass ratio of CA to SA is 9:1, with melting temperature 26.8°Cand latent heat of 96.4 J/g. The optimal load of PCM on waste autoclaved aerated concrete was 55%. In order to reduce leakage and increase strength of the aggregate, slag-water glass-gypsum binder was used for encapsulation, which also helped increase the compatibility with the main building materials. The simulation test showed that the phase change energy storage aggregate possesses good temperature control and energy storage performance.
