The soundness of ordinary and rapid hardening portland cement, low heat portland cement and class- A limes can be determined by an expansion test using Le-Chatelier moulds as specified in IS:5514, 1727, 2645, 4031, 6932 (Part-9), BS:890, 915, 1370, 4027, 4226 and 4248.
Le-Chatelier Mould with ISI Certification Mark,
Ref. Standard IS:5514
It consist of a small split cylinder forming a mould 30 mm internal dia. and 30 mm high. On either side of the split cylinder, two parallel indicating arms with pointed ends are fixed. The mould is supplied complete with two glass plates and lead weight.
Used for the determination of specific gravity of hydraulic cement as specified in IS:4031
Shinkage Bar Mould
Ref. Standard IS:10086, IS:4031
ASTM C 151 also specifies the use of shrinkage bar moulds for the determination of soundness. The change in length of the specimen is determined by Length Comparator listed in the concrete section. Two models are offered. One is provided with stainless steel smooth reference points and the other is provided with knurled and threaded reference points. Both the models are available as single mould and multiple mould compartments. Each mould is supplied complete with base plate and two reference points per compartment is mould.
Mould size : 25 x 25 mm section and 250 mm effective length (Distance between two inner-most of the reference points)
Set of 20, Smooth Reference Points
Set of 20, Knurled and Threaded Reference Points
