Preparation and properties of porous aerated concrete
INTRODUCTION Porous concrete, especially Aerated Autoclaved Concrete (AAC) was first developed by a Swedish engineer between the years 1920 and 1932 [1]. He was searching for a material with the properties of wood, but without the disadvantages of wood. Near the end of World War II, AAC became widely used. Vast areas of cities and industries lay in waste and tremendous rebuilding became necessa...
متن کاملNumerical simulation for the drying shrinkage of autoclaved aerated concrete
A mathematical model for the description of drying shrinkage of autoclaved aerated concrete (AAC) is presented, bringing together the hygrothermal and mechanical considerations. The verification of the model is done using an approximation of a real laboratory experiment. Then, the applicability of the model is demonstrated by a numerical simulation of drying shrinkage and wetting expansion of A...
متن کاملMaterials, Production, Properties and Application of Aerated Lightweight Concrete: Review
Aerated lightweight concrete have many advantages when compared with conventional concrete such as advanced strength to weight ratio, lower coefficient of thermal expansion, and good sound insulation as a result of air voids within aerated concrete. This paper is attention to classified of aerated lightweight concrete into foamed concrete and autoclaved concrete. Also, it is exhibits the raw ma...
متن کاملFibre reinforced autoclaved aerated concrete studied by computed tomography
The production process of fibre reinforced autoclaved aerated concrete results in a preferential orientation of the fibres. The fibre orientation largely influences the strength and the deformation behaviour of this building material, therefore information on the fibre orientation is highly desirable. Computed tomography measurements allow for the non destructive investigation of the material. ...
متن کاملGrowth of indigenous organisms in aerated filtrate of feedlot waste.
Filtrates from feedlot waste were incubated under aerobic conditions to evaluate the availability of nutrients for cell production and to assess the capacity of indigenous flora to produce stabilized effluents. Incubation was carried out in 9-liter aerated jar fermentors. Three-fourths of the organic material and one-third of the nitrogen were taken up in 4 days; 90% utilization of organic mate...
