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.

In this research, a new Thermal Insulating Concrete Block (TICB) is produced via “sandwich” structure by spent polystyrene foam, cement and other raw materials. According to the concerned China Standard Test Method for Building Material, the main properties of this TICB are measured successfully. By comparing its properties with those of autoclaved aerated concrete block as wall material, it can be concluded that comprehensive properties of this concrete block is better than those of autoclaved aerated concrete block. The extrusive advantage of producing this TICB is that large amount of spent polystyrene foam which is hard to be decomposed as industrial waste can be consumed. This is propitious to environmental protection and energy conservation. Therefore, TICB studied in this paper is one kind of green environmental wall material with bright prospect.

Through the mix ratio optimization test, the appropriate autoclaved aerated concrete block may be prepared for the production demand, whose technical indexes could satisfy the requirement of national specification. Furthermore, in the light of the research on the property of autoclaved aerated concrete block for this mix ratio, the strength of concrete block would decrease with the increase of total porosity among the pore diameter from 0.5mm to 1.5mm. The autoclaved aerated concrete block possessed the strong capability of absorbing water, so the volume water absorption rate increased quickly at first and then went down furiously, which could make the shrinkage of autoclaved aerated concrete block augment because of the decrease of its water absorption rate.

The Difference

As a common threat to the public safety, gas explosion and its damage on structures have drawn more and more attention in the academic fields. In this paper, a series of numerical simulations are conducted to study the behavior of autoclaved aerated concrete block infilled walls under gas explosion loading. Firstly, considering the difference between the blocks and the mortar, a refined numerical model is established, and the constitutive model of Brittle Damage in LS-DYNA is hired to describe the material behaviours of both materials. Based on the laboratory material test data, the parameter of the material model are selected reasonably. Then, massive numerical calculation is carried out and the dynamic response of autoclaved aerated concrete block infilled walls is captured and discussed. At last, the anti-blast ability of block infilled walls is compared with that of clay infilled wall of the same thickness. It is found that the anti-blast ability of block infilled walls is weaker than the clay infilled walls for the difference of material density and boundary conditions.
