What is Concrete Strength and what are the factors ...
In low grade OPC, the gain in strength will continue beyond 28th day. Due to early strength gain of higher grade of OPC the concrete strength do not increase much beyond 28th day. The heat of hydration of higher grade OPC being higher, the chances of microcracking of concrete is much greater.

FACTORS AFFECTING DURABILITY OF CONCRETE
Strength of concrete has a considerable influence on creep and within a wide range creep is inversely proportional to the strength of concrete at the time of appliion of load. From this it follows that creep is closely related to the watercement ratio.

4 MAJOR FACTORS AFFECTING CONCRETE MIX PROPORTIONS ...
For a given set of materials, strength is inversely proportional to the w/c. Since the materials which make up concrete are complex and variable, an accurate prediction of strength cannot be based solely on the selected w/c but must be confirmed by tests of cylinders made from trial batches with the materials to be used on the project.

Workability of Concrete
The cylinder is weighed to nearest 10 grams. This weight is known as "weight of fully compacted concrete". Compacting factor = (weight of partially compacted concrete) / (weight of fully compacted concrete) VeeBee test. VeeBee test is a good laboratory test suitable for stiff concrete mixes having low and very low workability.

Factors affecting the relationship between rate of .
However, ifa slower rate of loading is continued throughout the test, the ultimate strength is decreased significantly. This result is used to find the analytical form of the relationship between the stressstrain curve and strain rate of concrete and equations are proposed which closely agree with the existing data.

FACTORS AFFECTING DURABILITY OF CONCRETE
For example it is structurally possible to build a jetty pier in marine conditions with 20 Mpa concrete, environmental conditions can lead this structure to disastrous consequences. In addition to strength of concrete another factor, environmental condition or exposure condition has become an important consideration for durability.
