Assessing cement fineness. In the past, cement producers gauged cement fineness (i.e., cement particle size) by evaluating the specific surface area (SSA) or Blaine fineness and the sieve residue at various sizes. However, many producers now use particle size analysis techniques to assess fineness and help monitor the efficiency of the mill.

1.1 This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: Test Method A is the Reference Test …

1. Blaine air permeability test of cement. 2. Wagner's turbidimeter test. 3. Particle size distribution method. 4. Lea & nurses air permeability test of cement.

In this case problem was, Cement Mill was not performing as per its design parameters. It was a Vertical Roller Mill & is designed for rated capacity 215 TPH but its output was very low so specific power consumption was higher and contributing to loss in terms of production and in turn profitability. 2.1. Tools & Techniques Used 2.1.1. Data ...

Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.

(Weight of cement sample left on the sieve; W₂) Empty the pan and fix it below the sieve. Repeat the whole procedure, at least three times, using a fresh 100 g sample of cement. Totally sieve for 15 minutes and weigh the residue (weight of cement left over the sieve; W₂). Calculate the fineness of cement by formula W₂/W₁×100 % for …

The amount of concrete you need for a 10x10 slab depends on how thick it will be. So, for a 4-inch slab you'll need 1.24 cubic yards (56 80lb bags), but a 6-inch slab requires 1.85 yards (84 80lb bags). If your slab is a different size or thickness, use our calculator to determine the amount of concrete.
