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 is the ...

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 and ...

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 Test A ...

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 subjected ...

Earthquake Zones in India

India being a large landmass is particularly prone to earthquakes. The Indian subcontinent is divided into five seismic zones with respect to the severity of the earthquakes. The classification of the zones has been done by the geologist and scientist as ...
