HMKC1 Blaine Apparatus is a cement testing apparatus used to determine the particle size of portland cement, limes and similar powders using the Blaine airpermeability method. It gives accurate and repeatable test results of cement specific surface area. HMKC1 blaine apparatus consists of a stainless steel cell, perforated disc and plunger.
Total weight of residue = w 2 = gram % age of fineness = %. COMMENTS: "The fineness of cement is not according to the ASTM standard, so the cement is not perfectly fresh therefore it should not be used for making concrete where high strength is required but can be used for low load structures as fineness is not too bad".
