3.5.2 Concrete. Concrete is a widely used construction material, consisting of Portland cement, water, sand, gravel, crushed stone, and other materials such as expanded slag. In the oil and gas industry – as in any industry – concrete is used as construction material in buildings and in offshore platforms.
Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content. If a change is noted in the mill certificate, air-entraining agent dosages may need adjustment. Above 0.60%, alkali changes of 0.1% can be significant.
It is therefore extremely important to consider all individual milling parameters in order to make an informed choice: material properties, feed size and volume of the sample, grinding time and desired final particle size, any abrasion of the grinding parts ' …

Hammermill Crushers are known to generate material finer than 3/16" (4mm), which in some applications may be undesirable. However, if there is a market for finer material, or if it is acceptable within the desired product size, Hammermills can achieve reduction ratios that may otherwise require multiple crushers.
