can you please share your opinion about the what are the main levers to control the blaine and residue on 45 micron in cement product indivisually. take any case -1, our blaine is 3400 cm2/gm and residue on 45 micron is 13% and if we want to reduce the residue by 3% with out affecting the blaine, how it is posible? (or vise versa).

A cement company earns a profit of Rs. 8 per bag of white cement sold and a loss of Rs. 5 per bag of grey cement sold. The company sells 3, 000 bags of white cement and 5, 000 bags of grey cement in a month. What is its profit or loss?

The Blaine Fineness method covers the 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 centimeters per gram, or …

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 …

If the specific gravity value reaches 3.19, then the pores in cement are filled with moisture. Cement undergoes a chemical reaction when it is reacted with the atmospheric moisture this process is termed as hydration. Moisture is very harmful to cement. Cement becomes useless once it is hydrated with water.

Blaine's air permeability apparatus consists essentially of a means of drawing a definite quantity of air through a prepared bed of cement of definite porosity. The fineness is expressed as a total surface area in square centimeters per gram.

Lime Saturation Factor (LSF) is the ratio of the actual amount of lime in raw meal/clinker to the theoretical lime required by the major oxides (SiO 2, Al 2 O 3 and Fe 2 O 3) in the raw mix or clinker.It is practically impossible to complete the reaction to , in a reactor like rotary kiln, therefore there will always be some unreacted lime (CaO f) known as free lime.

It is used to determine the fineness of cement using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimeters per gram, or square meters per kilogram, of cement. ... Automatic formula correction for the calculation of the Blaine value with variation in temperature (as per ASTM ...

The Blaine Fineness method covers the 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 …

The Blaine value is a standardized measure for the degree of fine grinding of cement . It is stated as the specific surface area (cm 2 / g) determined in a laboratory using the Blaine device . Standard Portland cement CEM I 32.5 has a Blaine value of approximately 3000 to 3500. Is code for Blaine apparatus?

Fineness or particle size of cement affects hydration rate and thus the rate of strength gain. The smaller the particle size is, the greater the surface area-to-volume ratio, and thus, the more area is available for water-cement interaction per unit volume. Table 1: Blaine fineness of cement as a function of amounts of total feed and clinker

4.2.2 Calculate the bulk volume occupied by the cement to the nearest 0.005 cm3 as follows: V 5 ~W A 2 W B!/D (1) where: V = bulk volume of cement, cm3, W A = grams of mercury required to ﬁll the cell, no cement being in the cell, W B = grams of mercury required to ﬁll the portion of the cell not occupied by the prepared bed of cement in ...
