      Hello Raag,
      Self cementing means it has the ability to behave like a bonding agent. It has the ability to make good bonds. The bonding material required to fill the joints reduces to a great extent.

    I have used Fly Ash bricks for house construction. Vertical and Horizontal cracks are appearing on walls. Almost all walls cracks are appearing, day by day cracks are increasing. Red or clay bricks wall this much cracks will not appear. Expert comments are required. Kindly advise me how to construct with fly ash bricks with out cracks.

      Flyash bricks are better than regular bricks. If the walls are cracking, then that would mean structure is weak, and is causing beams to sag. Just a case of bad design.

    Dear mam,

    I am constructing an STP tank at the site its depth is 1.0 m x 7.0 m x 3.0 m…3.0 m being its depth.. Now my question is ..is it necessary to keep this tank away from boundary by 3.0 m..?? As the bounday wall is already constructed i dont want to use the wall of the tank as the foundation for the bounday wall… plz suggest the best posiible way. i consulted a senior and he made a reference to angle of repose..because of which the pressure exerted by water on tank wall should not be transmitted to boundary wall foundation.. but i am not clear with the concept.

      Hello Sriram,
      If you are so curious to find out the quantity of raw materials, then you should contact the manufacturer for details. That would be helpful.

      No. Over reinforced or Under reinforced sections are unsuitable for any kind of construction.
