Fineness Test of Cement; Its Apparatus, Procedure.

Fineness test of cement is done to determine 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. Sieving Method. 2. Air Permeability Method (Blaine Method).

A Quick Method for Determining Cement Content of Fresh ...

Several attempts have been made to devise a method of determining the cement content of fresh concrete. A few years ago a new concept of such a test was originated by R. A. Willis. To separate the cement from the aggregate, Willis employed a heavy liquid in which the aggregate would float but the ...

A Detailed Guide on Grading of Aggregates.

The binding property of cement is made use of to give this dense mass a cohesive stone-like character. Concrete is, an artificial stone, in a broad sense. Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates. This is commonly found by the Method of Fineness …

of a cement powder and is closely linked to cement performance. Presently, the only relevant standard method is ASTM C115-96, a turbidimetric method for determining fineness (Standard Test Method for Fineness of Portland Cement by the Turbidimeter ASTM C115). This method is limited in scope, however, with a lower size detection limit of 7.5 µm.
