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:
Reinforcing the hollow concrete brick Masonry, by taking advantage of hollow spaces of brick.
In Reinforced Hollow Concrete Brick Masonry, elements are designed both as load bearing walls for gravity loads and also as shear walls for lateral seismic loads, to safely withstand earthquakes. This structural system of construction is known as shear wall - diaphragm concept, which gives three-dimensional structural integrity for the buildings.
Due to the uniform distribution of reinforcement in both vertical and horizontal directions, through masonry element, increased tensile resistance and ductile behavior of elements could be achieved. Hence, this construction system can safely resist lateral or cyclic loading, when compared to other conventional masonry construction systems. This construction system has also been proved to offer better resistance under dynamic loading, when compared to other conventional systems of construction.
Reinforced Hollow Concrete Block Masonry (RHCBM) is a feasible disaster resistant building construction system.
The extensive experimental programme has revealed that RHCBM construction technique is structurally more efficient, not only because of its higher ultimate load capacity, but also due to its improved ductility when compared to the conventional reinforced or un-reinforced brick masonry. Hence, RHCBM can be adopted as a disaster resistant construction system for box type construction.
