ULTRA BRICKS
 
ULTRA BRICKS are Cement Concrete Bricks (closed cavity), manufactured in accordance with IS IS 2185 (Part1-1979, re-approved in 2003). As it is load bearing it is substitute for the conventional bricks (clay).

ULTRA BRICKS are in different sizes and grades as mentioned below:
The different grades are,
ULTRA A - 8 N/ Sq.mm
ULTRA B - 5.5 N/ Sq.mm

What is the difference between Conventional Cement Concrete Hollow Bricks and ULTRA BRICKS?

There are lot of differences ...

ULTRA BRICKS

 Ingredients

  • 12 mm metal, 6mm metal, M-sand & cement 
  • Designed mix for minimum voids & maximum density, as such the bricks will take more loads.

 Shape

  • Designed in such a way that the cross walls of successive layers will come just one above the other so that the web will also take the load. There for it will have more area per brick to take the vertical load.
  • As there is no notch vertical joints can be filled properly. 
  • Vertical reinforcement can be provided to make the wall ductile as envisaged in IS 4326 :1993
Are there advantages over conventional brick (clay) work?
Yes, there are:

Conventional Hollow Blocks

 Ingredients

  • Generally 6 mm metal & crusher dust.
  • Not Designed mixed, as such voids are more and not suitable for load baring walls.
 Shape
  • Cross walls (web) will not take the load (only the long walls will take the load) hence less area per brick to take the vertical load. As there is notch vertical joints has to be filled from the top, and filling will be laborious and will not be proper.
  • Vertical reinforcement cannot be provided. 
  • Five sizes (Ultra 22, 20, 19, 16 and Ultra 10) and three grades (A- 50 kg / cm2, B - 35 kg / cm2, C- 20 kg / cm2) to choose for different types of works.
  • Vertical reinforcement can be provided as envisaged in IS 2185 (Part1-1979, re-approved in 2003) to make the wall ductile and EARTH QUAKE RESISTANT with out additional work expense and expert labor force.
  • As joints (both horizontal & vertical) are less compared to the conventional bricks, ULTRA BRICK work will take more loads and the consumption of cement and sand are also low.
  • As the unit weight is less compared to the conventional brick work, the structural design will be cheap.
  • About 6 % more carpet area will get for the same plinth area.
  • Wiring can be done with out chasing the brick work.
  • Inside room temperature will be less by about 4 to 5 degree C.
  • Brick sizes are suitable for adopting Vasthu Sasthra.
