Superfine powder A powder of which not less than 90 percent by the number of the particles are less than 10 micron size. When the fineness of the powder is described by means of a number, it is intended that all the particles of the powder shall pass through a sieve of which the nominal mesh aperture, in /lill, is equal to that number.

Feb 08, 2021 When the fineness of slag powder is too low, the tendency of mortar segregation and bleeding will increase, which would also lead to a reduction in mortar fluidity. Regarding the hardened mortar, the ball-milled slag powder possesses better strength properties than does the vertical-roller-milled slag powder at all ages.

1.1 This standard prescribes methods of test for mineral gypsum. It covers the methods for determination of fineness, free -water, combined water, carbon dioxide, silica and acid insolubles, iron and aluminium oxides, calcium oxides,, magnesinm oxides, sodium chloride, sulphur trioxide, and various forms of calcium sulphate.

- An increase in fineness increases the amount of gypsum required for proper retardation because, in finer cement, more C 3 A is available for early hydration (due to the increase of its surface area). Fineness of cement is tested in two ways: (a) By sieving.
tested gypsum samples water gypsum ratio 0.81 (Fig. 2). The last criterion is the fineness of grinding, where the tested gypsum is medium ground and the fineness of grinding is marked II in our case. Used water-gypsum ratio was 0.71 and corresponded with normal consistence of gypsum paste after standard ČSN 722301. TABLE I
