Cement Testing Equipments

We are offering our customers a wide range of Cement Testing Equipments. This property of soundness is tested by subjecting the set cement to boiling in water or to high-pressure steam. Unsoundness can arise from the presence in the cement of too much free magnesia or hard-burned free lime

This method covers determination of the autoclave expansion of Portland cement by means of a test of neat cement paste specimens, 25.4 X 25.4 X 285.8mm, which are moist cured for 24 hours +/- 1-1/2 hours and then exposed to action of steam under specified pressure for 3 hours. The rate at which pressure is increased in the beginning the test and released in the test are specified. Linear expansion is measured by micrometer comparator.

SALIENT FEATURES :
