Where should be a construction joint provided in slab and beam?
Construction joints should be provided in slabs and beams at locations where it is necessary to stop pouring concrete temporarily and resume later. These joints are typically located at points of minimum shear and bending moment to ensure the structural integrity of the slab or beam. They should be planned keeping in mind the structural design and construction sequence to avoid any stress concentrations or discontinuities. Additionally, joints should be properly sealed and reinforced to ensure durability and prevent any further movement or cracking.
Why should large concrete slabs be laid with expansion so that they are not touching?
because large slabs of concrete have expansion joints between them.
Why are pieces of rubber placed between slabs of concrete?
Concrete expands and contracts depending on the temperature. The strips are called expansion joints.
What is the reason for caulking control joints in concrete slabs?
If you live in an area that has temperature below 32 degrees F during the winter you need to caulk joints. Water can get in the crack and cause freeze cracking. Water expands when it is frozen.
What are the advantages of using flat slabs in building construction?
- they are more economical- constructional simplicity (no difficulty in placement of form works)- room layout & flexibility- short construction period- requires no more labor etc...
What is the approved location of the construction joints in the raft foundation?
The best location to set the construction joint is less shear force impact. e.g:In slabs;it is better to locate between the supports.

What are concrete slabs used for in construction?
Concrete slabs are a common building material. Sometimes they are re-enforced with steel roods for extra stability. Concrete slabs are either prefabricated or created insitu.
Why do concrete slabs have space between them?
Those are expansion joints. During the changing seasons with varying temperatures, the slabs expand and contract. The spaces allow the slabs to expand without cracking the concrete.
What is mivan construction?
Mivan Technology involves columnless , beamless construction but usually all walls & slabs are of 150mm concrete and slabs as a whole. Pre-planning is required to leave openings for doors,window & services shafts in shuttering itself.

What type of rock is gniess?
Gniess is mainly mined for use in construction--building slabs, countertops, stone facings.

What is the minimum distance allowed between two manholes in sewer?
Outside diameter (OD) of adjacent manholes (including the bottom slabs) should have minimum of five (5) feet horizontal clearance.
