Question

le chatelier apparatus is used to carry out

Answer 1

To find out the Soundness of Cement.

Answer 2

Answer:

Soundness of cement is the ability of a hardened paste to retain its volume after setting. A cement is said to be unsound (i.e., having lack of soundness) if it is subjected to delayed destructive expansion.

Soundness of cement indicates quality to expand on the setting. Unsound cement expands too much on setting and develops cracks in the structure.

The test used for determining soundness of cement is known as “Le chatelier apparatus test.”

It consists of a small, split, metallic cylinder having an internal diameter of 30 mm. It is 30 mm in height, with the thickness of wall being 0.5 mm.

It is fixed with two indicators, one fixed on either side of the split. The distance from the end of the indicator to the center of the cylinder is 165 mm.

By soundness of cement, it is understood that, its capacity to form a non-disintegrating, hard uniformly strong mass on the setting.
