This document reports on an experiment to test the fineness of gypsum according to IQS standard 28/1988. Fineness affects the hydration and strength of gypsum. A test was conducted on 3 gypsum samples by sieving 200g of each through a #16 sieve and measuring the amount retained. All samples met the specification of less than 8% retained, with results ranging from 2.1% to 3%. The test helps ensure gypsum is suitable for construction projects. Accurate sieving is important to avoid error.
