Soil Cement Interlocking Blocks
Brick masonry is well proven building material possessing excellent properties
in various terms, for example appearance, durability, cost etc. However, the quality of masonry in a building depends on the materials used and hence all brickwork materials must confirm to certain minimum standards. The basic components of brickwork are brick and mortar. The latter being in itself a composite of cement, lime and sand and sometime of other constituents.
All these bricks either produced by machines or manually using skilled or unskilled labor require mortar joints and some degree of skill for placement when building walls. It also consume labor's time. Furthermore, since bricks are mostly solid, the wall becomes rather massive and oversized for single storey load bearing construction while being insufficiently stable for multi-storey construction. In addition, conventional mortar joints allow only light reinforcement to be used, making the wall an unstable structural component for use in earthquake zones.
Interlocking Brick is inexpensive and can be used without cement or mortar, easy to handle, mould and manufacture. Even unskilled or semiskilled labor can easily and quickly construct a wall.
The interlocking blocks are different from other normal bricks. They are rectangular in shape as regular bricks, but they do not require mortar for the masonry work. They are interlocked with each other by means of positive and negative frogs on the top and bottom of the bricks which do not allow horizontal movement between them. They can be used for all kinds of structures like load bearing walls, lintels, sills, walls corners etc.
The interlocking bricks can be produced with stone dust or laterite soil and cement.
The general steps are as follows:
Construction costs are 30-50% less than conventional systems
1. Half Size Brick 2. Regular Shaped Brick
3. U- Shaped Brick
