Le Chatelier Water Bath Soundness Of Cement Hydrated Lime Utest Soundness of cement can be defined as its ability to retain its volume after it gets hardened. this means that a properly sound cement will undergo minimum volume change after it converts into the hardened state. in the soundness test of cement, we determine the amount of excess lime. this test can be conducted by le chatelier method and. Soundness expansion of cement = l 1 l 2. l 1 =measurement taken after 24 hours of immersion in water at a temp. of 27 ± 2 0 c. l 2 =measurement taken after 3 hours of immersion in water at boiling temperature. calculate the mean of two values to the nearest 0.5 mm. note::in the event of cement failing to comply with the specified requirements.
Le Chatelier Water Bath Soundness Of Cement Hydrated Lime Utest Soundness test of cement calculation. the soundness of cement = l1 – l2. where l1= distance 1 and l2= distance 2. l1=measurement is taken after 24 hours of immersion in water at a temp. of 27 ± 20°c. l2=measurement was taken after 3 hours of immersion in water at boiling temperature. Fig. 3: water bath water bath with means of heating, capable of containing immersed le chatelier moulds with specimensand of raising their temperature from 27±2°c to boiling in 27±3 minutes. fig. 4: vernier calliper vernier calliper should be able to measure upto 30 mm with least count of 0.1 mm fig. 5: balance. The soundness test of cement is one of the methods to determine the volume change in cement and concrete after the setting. excessive expansion after the setting is said to be unsound. it is done by two methods namely le chatelier method and the auto clave test. le chatelier method is only applicable for that cement containing free lime while. Mixing for 4±1 4 minutes. fill the cylinder with cement paste. the cylinder placed on glass plate and covered by another glass plate. put the small weight on the glass plate. immerse the cylinder in water (20±1 oc) for 24 hrs. take out the cylinder from the water bath and measure the distance between the two indicators.

This video (animation, animated video) explains how to perform a soundness test on cement by le chatelier method.(civil engineering animated videos, civil en. The test used for determining soundness of cement is known as “le chatelier apparatus test.”. by soundness of cement, it is understood that, its capacity to form a non disintegrating, hard uniformly strong mass on the setting. this depends on its original composition, proper burning, and grinding. presence of lime in the free state, an.
