fineness cement determine

Apr 12, 2020· A Fineness of Cement isMeasure of the size of Cement Particle, and it isdescribed in terms of the specific surface area of Cement particle. The Fineness of cement can be Calculated by particle size analysis, by using the air permeability method, by using sedimentation method.

    Fineness Test of Cement; Its Apparatus, Procedure

    Fineness test of cement is done todetermine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1.

    Procedure to Determine Fineness ofCement Stir the sample of cement to be tested by shaking for 2 minutes in a stoppered jar to disperse lumps. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. Attach a pan under the sieve to collect the cement passing the sieve.

    The fineness of cementinfluences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased. However, if excessive bleeding due to coarseness of the cement takes place, a reduction in the drying shrinkage occurs. 8.
