ASTM-C472 | Standard Test Methods for Physical Testing …

These test methods cover the physical testing of gypsum, gypsum plasters, and gypsum concrete. Test methods are detailed for the following: precautions for physical tests, reagents and materials, free water, fineness, normal consistency of gypsum plaster and gypsum concrete, setting time, setting time (temperature rise method), compressive strength, and density.

Gypsum

Gypsum was formed by sedimentary deposition processes. In order to use gypsum as a building material, the crushed and ground gypsum is dried in a kiln. Depending on the temperature of the kiln, different building gypsums for different properties are produced.

Fineness of Cement

An increase in fineness increases the amount of gypsum required for proper retardation because, in a finer cement, more C3A is available for early hydration. The water content of a paste of standard consistency is greater the finer the cement, but conversely an increase in fineness of cement slightly improves the workability of a concrete mix.

Test To Check Fineness Of Cement

FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size. The apparatus used are 90µm IS ...

 · It is well known that gypsum, CaSO42H2O, dehydrates at temperatures above 80°C. It first loses 1½ molecules of water to form the substance hemihydrate, CaSO4½H2O (plaster of Paris) and then with further heating at higher temperature it dehydrates virtually to completion to form ''dead-burnt gypsum''.* Where pure, gypsum crystals are generally colourless, but hemihydrate and ''dead-burnt ...
