Workability Requirements for Different Concrete Placement: Requirement of concrete workability varies with different types of construction. Workability of concrete is decided by design engineers based on concrete strength requirements, durability requirements and ease of construction at site. For a construction ...

Grain Size Analysis of Aggregates – Particle Size Distribution Test
Test for grain size analysis or sieve analysis of aggregates are done to determine its particle size distribution, fineness modulus, effective size and uniformity coefficient. Grain Size Analysis of Aggregates Fine aggregate is the sand used in mortars. Coarse aggregate ...
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 procedure ...
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 Gravity ...
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 are ...
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 test ...
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 to ...
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 not expected ...
