This article takes an actual public building in Changchun City as an example to field test the heat transfer coefficient of fly ash autoclaved aerated concrete exterior wall. By analysis the field test value, theory calculation value, and the maximum value of the design standard for energy efficiency of public building (GB50189-2005), I concluded that fly ash autoclaved aerated concrete self-thermal insulation building envelope exterior wall fully meet the energy-saving standard requirements, which does not need additional insulation material. And further as heat transfer coefficient of wall test and energy saving standard maximum heat transfer coefficient as the main parameter, I used DeST-c software simulation to calculate the building energy consumption. The simulation results showed that the heating energy consumption of fly ash autoclaved aerated concrete self-thermal insulation building envelope is 16.32% lower than the standards required value, which has the advantage of energy saving property.

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.

In this paper, the low-silicon coal gangue fly ash is used to produce autoclaved aerated concrete. The influences of water binder ratio, coal gangue fly ash content, calcareous content and conditioning agents on the compressive strength of the autoclaved aerated concrete are investigated. Optimal raw material formulation and procedure are determined for the autoclaved aerated concrete. The compressive strength and frost resistance of autoclaved aerated concrete made by the optimal raw material formulation and procedure meet with the requirements of autoclaved aerated concretes of B05 grade, and its thermal conductivity, drying shrinkage reach the requirements of the relevant national standards of China.
