In the manufacture of clay bricks, the topsoil is depleted and natural resources are eroded, resulting in ecological imbalances. But by utilizing fly ash which is the waste material generated by thermal power stations, we will be saving the natural resources on the one hand and putting the industrial waste into productive use.
This makes #AACBlocks one of the best examples of a truly “green product”, in every sense of the term. Sand is another alternative to fly ash for manufacturing AAC Blocks. However, sand cannot be recycled like fly ash and therefore, manufacturing #AACBlocks using sand cannot be considered a green process and the resultant product a green product. Using sand will only erode the natural river bed, thereby changing its course and result in ecological imbalances.
As every structural engineer knows, adequate care must be given to masonry wall members since it gives full shape and structure to the building. I have realized that everyone neglecting the wall member in the structure will mean that importance of the masonry wall will have been neglected by all parties concerned – structural consultants, builders, promoters, contractors, etc. This will mean not following the specifications laid down in BIS 6041 of 1985 and BIS 1905 of 1987, which will lead to problems like shear crack, horizontal crack and settlement crack, etc., in the wall at a later date. I, therefore, appeal to all friends, contractors, constructors, builders, etc, to follow certain essential guidelines given below before and during the construction of the AAC masonry wall for better achievement.
