   I am from North east india(NEI) and I have recently introduce this techonoly. and I am yet  to understand the details of consrtuction. I am producing blocks using stone dust(coarse and fine mix together) and the ratio  with cement ratio of (1:8). NEI fall under high seimic zone and most people who have seen this technology often ask me wether it is possibe to have two floors. I am constructing a 30 ft by 30ft single storey building as demo. I would like some info on how to raise columns and tie beams for floor slab. We don get percast slab in this part of the world.
  I would like to mail photos of the construction for more feedback

Dear Lalboy,
I admire your courage in using a technology that is new in your area.

  • For some construction information (mainly for non-earthquake construction) you can see
  • Which state are you in and what is your seismic zone classification?  What is your expected ground acceleration?
  • You can have two floors, you just need to do your structure well.  The best thing is to check with a structural engineer.  They will calculate the masses of your building, the forces that will act on it, and the size of the walls you need and the reinforcement you'll need.
  • 30 ft x 30 ft.  That would be 10 meters by 10 meters.  Single story.  You need a wall layout that provides some structural stability (intesecting walls or buttresses).
  • Are you asking about the bottom floor slab or the top floor slab?  As an alternative to precast you can use joists and cast insitu floor.
  • I believe you can post photos or attach photos to posts or plans (pdfs are good) to this forum.
