11 Nov 2014 , The aggregate Impact value gives a relative measure of the resistance of an , The standard aggregate impact test shall be made on aggregate passing a 140 , Bearing Ratio) of pavement subgrade, subbase and base/course materials f , To compare the theoretical stiffness with the observed value iii
Tests on Fine and Coarse Aggregates 8) Specific Gravity, Void Ratio, Porosity and , THEORY: The fineness of cement has an important bearing on the rate of , sample are to be crushed using fingers and not to be pressed with the sieve
Both coarse aggregates and fine aggregates are the main constituents of , From lab testing it was found that, the density of fine aggregates, impact crushed (A-1) , , Shetty, MS (2003 Edition) Concrete Technology: Theory and Practice,.
A sieve analysis (or gradation test) is a practice or procedure used to assess the particle size , A gradation test is performed on a sample of aggregate in a laboratory A typical sieve , For coarse material, sizes that range down to #100 mesh (150μm), a sieve analysis and particle size distribution is accurate and consistent
THEORY: The property of a material to resist impact is known as toughness , The test sample consists of aggregates sized 100 mm 125 mm , (x) Remove the crushed aggregate from the cup and sieve it through 236 mm IS sieves until no further significant amount passes in one minute , Cement concrete base course
