For centering platforms, rough planks suitably supported and leveled up with earth and finished at the top with cement plaster with neat cement punning should be done as directed by the Engineer-in-Charge. All forms should conform to line and shape according to the requirement of design of the finished RCC works. The whole assembly should be strong and rigd enough to stand any incidental load, including wind pressure without any vibration, deflection and distortion. The form must be strong enough to remain such disturbed during vibration of concrete. 2.7.3. Before arranging reinforcement in the forms the interior surfaces of the later which have to remain in contact with the concrete shall be very lightly smeared with non staining material approved materials to prevent them from adhering to the concrete.

2.7.4. In some locations RCC is laid over or between masonry of concrete or over ground. In such cases forms are not required and reinforced concrete is to be laid over existing masonry or concrete. The later being previously moistened to prevent from stacking any water from the cement concrete. When laid directly over earth in foundation the bed shall be watered and rammed hard. 2.7.5. REINFORCEMENT: The steel bars shall be free from any loose scale or loose rust. The bars must not be painted or oiled. The bars shall be cut and bent cold to the required shapes and placed in position according to drawings and ties firmly in their places with the help of plain soft annealed iron wire 15 S.W.G. unless otherwise shown in the drawings.

Bars of sufficient length should be obtained so as to avoid the necessity of joints but when this is not possible joints should be staggered and located at points of low stresses and a lap splice provided as per the direction of the Engineer-in-Charge. The minimum cover of concrete shall be as per drawing. The cover shall be accurately maintained by small percent of concrete chairs under the bars to be incorporated with the work or lying from above. Bars of required diameter will be utilized as per direction of the Engineer-in- Charge.

2.7.7. The reinforcement after it has been placed and arranged in the forms and tied in position by wire shall be checked and finally passed and measured by the Engineer-in-Charge or his authorized agents after which only the concrete shall be laid. The principles of mixing, laying and curing should be adopted same as in plain cement concrete.

2.7.8. CONSTRUCTION JOINTS: Joints should be located at positions of minimum shear centers of spans of ordinary slabs, junction of slabs and ribs in case of T- Beams are normal position of construction joints. Sloping joints are not to be employed except in curved members like arches. The joints are to be perpendicular to be main thrust. When resuming work on the hardened concrete surface of the joints it shall be thoroughly cleaned, roughened and all litance removed. The surface then shall be swept clean with wire brushed thoroughly wetted and treated with a thin layer of cement mortar 1:2 and the new concreting shall then be done against this layer.

SUPERVISION AND GENERAL ATTENTION: All operation with reinforced concrete shall be carried out under the strict departmental supervision, Reinforcement shall not be laid in the forms before the later has been passed as fit by a responsible P.W.D. Officer. After laying reinforcement the concrete should not be laid until the reinforcement fixed in position has been passed by the Engineer-in-Charge or Officer deputed by him. Mixing and laying should not be done in absence of the Departmental officers.

The face stones are selected over as large as an as nearly the same size as practicable going well into the interior of the masonry with a few smaller stones in the hearting joints must not exceed ¼ “ and stone chips are wedged into the interior joints whenever necessary to prevent occurrence of thick joints. Face and interior edge stones should be placed with broadest face downwards. 2.8.2. PREPARATION OF STONE, JOINTS AND BEND: Stones as received from quarry shall have their week comers and edges knocked off with a hammer. Face stone shall have their faces hammer dressed sufficiently to fit fairly on the faces. Fifty percent of the face stones must not be less than 1 Cft. And 25” must be headers running not less than 15”in the hearting where required. 33% of the stones used in the hearting should be ¾” Cft. Smaller stones should be used as less as possible to avoid joints and no joints shall exceed ½” thickness. Greater care should be taken not have hollow spaces in masonry. 2.8.3. MORTAR: Proportion of mortar will be as per specification of tender schedule. Greater care may be taken for dry masonry to provide through stones, stones breaking joints and avoidance of small stuffs in the interior. 2.9. WELL BURNT C.B.
