Student‟s t-test can implicate regression coefficient of the parameter. It is noted from table-3.4 that more significant corresponding coefficient term can be possessed by having high „t‟ value and low „P‟ value. By analyzing „t‟ and „p‟ values from table-5.7, X1, X2, X3, X4, X12, X22, X32, X42, X3X4 and X1X4, have high ...

Strength of concrete in the hardened state is usually measured by the COMPRESSIVE STRENGTH using the Compression Test. See CHAPTER 3 Concrete Testing Strength and Durability are affected by: COMPACTION Compaction is removing the air from concrete. Proper compaction results in concrete with an increased density which is stronger and more durable.
