Strength development in concrete

Concrete strength Many factors influence the rate at which the strength of concrete increases after mixing Some of these are discussed below , As the porosity increases, the compressive strength of the concrete will decrease Soundness of aggregate: it will be obvious that if the aggregate in concrete is weak, the concrete will also be .A Concrete shall be used as follows: 1 ODOT 499 Class C (ASTM Class A) Concrete fo r all concrete work except as noted below or elsewhere in these specifications a 4,000 psi compressive strength at 28 days b Type II cement plus dispersing agent and air.

Prestressed Concrete

Compressive Strength Added Compressive stresses are induced in prestressed concrete either by pretensioning or post-tensioning the steel reinforcement In pretensioning, the steel is stretched before the concrete is placed High-strength steel tendons are placed between two abutments and stretched to 70 to 80 percent of their ultimate strengthSpecified concrete compressive strength is the minimum compressive strength at which the concrete should fail in standard tests of 28-day-old concrete cylinders A typical concrete compressive strength specification requires 4,000 to 5,000 psi at 28 days.

Compressive strength test

Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturingThe test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied loadThe compression test shows the compressive strength of hardened concrete The compression test shows the best possible strength concrete can reach in perfect conditions The compression test measures concrete strength in the hardened state Testing should always be done carefully Wrong test results can be costly.

Strength of concrete Q Is compressive strength the only strength factor of interest? A No, in the early development of concrete, compressive strength was the primary interest and it became the natural basis for recording the results of experience and researchCompressive strength, tensile strength and modulus of elasticity of concrete were tested at 1, 7 and 28 days of hardening and at a day, when concrete ring was cracking Cube specimens 100 mm and 150 mm were used for compressive strength , cubes 100 mm for tensile strength, and cylindrical specimens measuring 150×300 mm for modulus of elasticity.
