Automatic control of fineness modulus is the key technology in this process. Typical features are listed below in detail. 1. German sand producing host machines are equipped and of low energy consumption, low cost, good particle shape, and stable grading. The impact rotors in two cavities largely increase the crushing effect and reduce the ...
This apparatus is widely used to determine cement fineness. Air flow takes the role as dynamic media. The whole system is under negative pressure, specimen under test will be in flow state under the action of airflow sprayed by the rotating gas nozzel, and travel along with airflow.
Table 1: Recordings during Compressive Test on Cement . 6. calculation; The measured compressive strength of the cubes shall be calculated by dividing the maximum load applied to the cubes during the test by the crosssectional area, calculated from the mean dimensions of the section and shall be expressed to the nearest N/mm 2.
The 28day compressive strength modulus of elasticity of concrete, with or without entrained air, increases with an increase in cement fineness. The difference in compressive strength due to difference in fineness of cement is considerably less at 1 year''s age. Increased Drying Shrinkage.

There is another factor to take into account when considering workability of concrete. This factor is the fineness of the cement particles themselves and their positive effect on concrete workability. eg "As per our findings, with an increase in the fineness of cement, both consistency of cement and workability of concrete increase.

The fineness of cement is directly proportion to the strength of concrete. The more finer the cement, the high heat of hydration and higher initial strength generation and hence much more compressive strength. But the fineness of cement is general...
improve workability [11,12]. When the fines content in sand are excessive, there is the need to add more water to the concrete mix in other to improve the workability. That is fine particles such as clay and cement interact with water in a physiochemical state which leads to more absorption of water than that of fine and coarse aggregates.

Fineness Standard EN 1966 describes two methods of determining the fineness of cement: sieving method air permeability method ( Blaine) Sieving Method This method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling production process.
