What is Bulking of Fine aggregate (Sand)? The increase in volume due to increase in moisture content is known as sand bulking. A film of water is formed around the sand particles, which forces the particles to receive one side from the other and thus the volume increases. Read more : Method of Deleterious material …
Determination of maximum dry density and optimum moisture content of soil by modified proctor test (Heavy compaction test). Test standard : IS 2720-Part 8: 1983 Test Apparatus Cylindrical mould of 150mm diameter of 2250 cm3 or 100mm diameter of 1000 cm3capacity with base plate and collar.

COMPRESSIVE STRENGTH OF CEMENT The compressive strength of the cement cubes is the maximum load applied to the cubes during the test divided by its cross-sectional area. The average of the three specimens at each specified age shall be calculated. This method covers the method of compressive strength test of cement motor cubes compacted by …
SOUNDNESS TEST OF AGGREGATE This method of aggregate testing covers the determination of the soundness of aggregate by measuring the resistance to disintegration in a saturated solution of Sodium sulphate or Magnesium sulphate. The soundness test of aggregate determines an aggregate resistance to disintegration by weathering. The aggregate sample is repeatedly immersed in a solution …
DETERMINATION OF DELETERIOUS MATERIALS IN COARSE AGGREGATES (SOFT PARTICLES) This method of aggregate testing covers the process of determination of soft particles ( Deleterious materials) in coarse aggregate on the basis of scratch hardness. Test Standard : IS 2386-Part 2: 1963 Test Apparatus : 1.6mm diameter Brass rod with Rockwell hardness of 65RHB to 75RHB …
