Aggregate Crushing Value Test | Crushing Value of Aggregate | Crushing Strength of Aggregate

  Aggregate Crushing Value is a relative resistance of aggregates to crushing under gradually applied compressive load The aggregate Crushing Value Test is an importanttest to be performed onaggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm in diameter and 25...

Modified Proctor Test

Modified Proctor Test is performed to know the characteristics of soil through compaction with change in water content ultimately giving us the relation between dry density and moisture content. It is a modified version of the Standard Proctor Test. Modified Proctor...

Standard Proctor Test

Standard Proctor Test is carried out to study or understand the soil’s compaction characteristics with variable moisture content.  The test is performed to estimate the maximum load the soil could bear hence ultimately reducing the voids present in the soil. The Proctor Test is one of the basic tests carried upon soil...

Soil Consolidation Test Procedures

Soil consolidation test refers to the process by which the volume of a partially or fully saturated soil decreases due to an applied stress. When a load is applied to a low permeability soil, it is initially carried by the water that exists in the porous...

CBR Testing

4 July 20220 Comments

What is CBR Testing?

CBR Testing (California Bearing Ratio) is primarily undertaken to provide data for road pavement design. It was first developed by the California State Highway Department. It is a penetration test which is used to evaluate the subgrade strength primarily of roads, pavements and foundations. The CBR test often forms part...

Concrete Cube Testing

4 July 20220 Comments

Why does concrete need to be tested?

The purpose of a concrete cube test is to ensure that the concrete meets its expected compressive strength. If the concrete doesn’t hit its design strength – or if it hasn’t been tested – the supplier can’t guarantee its quality. And if the supplier can’t guarantee...

Initial Time of Set of Fresh Concrete

2 July 20220 Comments

Initial Time of Set of Fresh Concrete - Use this method to determine the initial time-of-set of fresh retarded concrete in the field. This method describes a procedure that uses a penetration resistance apparatus and the mortar fraction of the concrete. The values given in parentheses (if provided) are not standard and...

Concrete Flow Table Test 

Flow Table Test is also used to identify transportable moisture limit of solid bulk cargoes. It is used primarily for assessing concrete that is too fluid (workable) to be measured using the slump test, because the concrete will not retain its shape when the cone is...
