## Bulking of Sand – Cause, Tests and Importance

Bulking of fine aggregate or sand is the phenomenon of increase in sand volume due to the increase of moisture content. Bulking test on fine aggregates has to be performed before using it in construction. This article describes the ...

## Determination of Specific Gravity of Fine Aggregates

Specific gravity of fine aggregate (sand) is the ratio of the weight of given volume of aggregates to the weight of equal volume of water. The specific gravity of sands is considered to be around 2.65. Apparatus for Specific ...

## Aggregate Crushing Value Test – Determine Aggregate Crushing Strength

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates ...

## Determination of Soundness of Cement by Le-Chatlier’s Principle

Soundness of cement can be defined as its ability to retain its volume after it gets hardened. This means that a properly sound cement will undergo minimum volume change after it converts into the hardened state. In the soundness ...

## Determination of Specific Gravity of Cement and Its Importance

The specific gravity is normally defined as the ratio between the weight of a given volume of material and weight of an equal volume of water. The portland cement have a specific gravity of value around 3.15. When it comes ...

## Splitting Tensile Strength of Cylindrical Concrete specimen

The tensile strength of concrete is one of the basic and important properties which greatly affect the extent and size of cracking in structures. Moreover, the concrete is very weak in tension due to its brittle nature. Hence. it is ...

## Tests on Hardened Concrete for Quality Check of Construction

Hardened concrete gains strength with time and testing these hardened concrete for quality check is important for structures. Different types of tests are available to check different properties of hardened concrete which are discussed. Properties of Hardened Concrete Early ...
