Graph For Compressive Strength Of Concrete Vs Age

Graph For Compressive Strength Of Concrete Vs Age

A total of 39 sets of data were used to analyse the behaviour of the concrete with time age. For the purpose of the Multiple Linear Regression MLR the data was randomly split into two . Figure 3 shows the typically seen Abrams plot of the concrete 28 day compressive strength vs watercement ratio and 728 day ratio for the data under .

    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.

    Strength of concrete The compressive strength of concrete is measured by how much force is required to crush it this is important in the design of structures. In pavements and other slabs on the ground the design is usually based on flexural strength i.e.; how much force the concrete can withstand in bending before it breaks.
