Strengths than larger sized coarse aggregates. Cook observed that the difference in compressive strengths due to aggregate size is increasingly larger with a decreasing water-to-cement ratio and increasing test age. The smaller sized coarse aggregate also increases the flexural strength of the concrete.

Pre-stressed concrete is a form of concrete used in construction. It is substantially prestressed during production, in a manner that strengthens it against tensile forces which will exist when in service.

Pre-stressed concrete is a form of concrete used in construction. It is substantially prestressed during production, in a manner that strengthens it against tensile forces which will exist when in service. According to the construction methods there are two kinds of prestressed concrete :-
– Pre-tensioned concrete
– Bonded Post-tensioned concrete
– Unbonded Post-tensioned concrete
The three types of members in prestressed concrete are as follows:-
1. Neither allowing tension nor crack.
See less2. Allowing tension within permissible stress but cracking is not allowed.
3. Tension and crack both are allowed but within permissible stress.
