Popping and Pitting Test of Lime Objective To determine popping and pitting of lime sample as per IS-6932-part-10 Theory This test is a measure to study the unsoundness of building limes. Popping, pitting and blowing are due to the presence of coarse unslaked or only partially slaked particles. On final slaking, these cause dislodgement of … Read more
Lime Reactivity Test Purpose This method of test covers the procedure for determining the reactivity of the pozzolanic material (such as fly ash) with hydrated lime, as represented by compressive strength of standard mortar test cubes prepared and tested under specific conditions. Size and Number of Test Specimens The tests specimen shall be 50 mm … Read more
Test to Check Total Calcium Oxide in Lime Purpose The lime should have a purity of at least 70% by weight of CaO when tested as follows: Procedure Take one gram of powdered lime, accurately weighed, in a platinum crucible. Place it in an oven maintained at 105 + 20C until, on cooling and weighing, … Read more
