Procedure of RCC roof flooring

RCC stands for Reinforced Cement Concrete. To enhance the load carrying capacity of concrete it is reinforced with steel bars (Rebars) of different diameters provided in an appropriate manner. Such concrete is called Reinforced Concrete and the rebars are called the reinforcement. These rebars are provided at various locations in the required number and diameters to resist the internal forces, which are developed due to the loads acting on the structure. The brick tiles being porous and moreover laid on mud and mud-plaster duly grouted with cement sand mortar do not gain too much heat in summer and thermo-action is negligible, therefore cracks do not occur in the joint of brick tiles. Whereas the marble/ kotah stone or terrazzo tiles which are generally laid over a bed of cement mortar after laying brick-ballast concrete on R.C.C. roof, gain heat too much and due to thermo-action, hair cracks occurs in the joints of stone slabs and tiles even in the first summer. When there is a continuous rain, the water penetrates in the roof through the hair cracks in the joints and dampness will appear under the roof slab. Slab under the bed of stone slabs and tiles in terrace floors and floors of bathrooms etc. The rich concrete without proper re-enforcement is prone to cracks due to thermo-action. Some professionals and masons suggest the laying of "Kuba" i.e. brick-bats grouted with sand mortar on the R.C.C. Slab which is also not suitable.
Low Cost Housing is a new concept which deals with effective budgeting and use environmentally friendly materials which are substitute for conventional building components like use R.C.C. Door, floor and window frames in place of wooden frames.
Generally, the stone/tiles laying contractors and masons mix the cement sand mortar with water minimum for half day work, when the ordinary Portland cement mortar begins to set after 30 minutes and completely set after 600 minutes. When the setting of cement mortar starts, the unused cement sand mortar will start to loose strength gradually.
It is not out of mention here that even the stone flooring of toilets & kitchen washbasin give dampness in walls due to leakage through the joints of junction because their back surface is not made water/damp proof. Similar is the case of stone cladding of outer walls during the rains. It happens because stone has no cohesive property being of plain surface and gaining more heat being homogeneous. In outer walls it some time disintegrate during summer and causes fatal accidents.
Waterproof coating system goes deep into providing classy performance along with minimum disturbance, waste & pollutants to the occupants and surroundings. The range covers right from New RCC Roof Waterproofing up to Load-free Waterproofing on old porous Lime-terrace. Even in standalone cement modifier range, the Products stands out in quality by technical advantages like sub-zero-tg, non-migrating plasticizer & core-shell molecular structure.
The Waterproofing systems are conveniently made up of unit modules, which are permuted and combined to build various Systems depending on required service and conditions. The 'Solution' System approach and uncompromised quality of Products deliver foolproof reliable performance
