What is dense phase conveying system?

Dense phase conveying is a term to describe the maximum amount of product that can be moved inside a pipe with the least amount of carrying medium. Typically this is most commonly used in relation to powder forms like cement powder being transferred inside a pipe using compressed air as the fluidizing medium. There is a specific amount of air that can be fed into a powder form that will make the powder flow like water. If you reduce that air amount then compress the powder you can pump it a substantially long way though a pipe with as little as 5% air per volume. Reaching this level is generally known as dense phase transfer.


Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?

True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.

Is asbestos ever found in Portland cement?

Under normal circumstances we would not find asbestos in Portland cement. Asbestos has a number of applications (even though it is hazardous), but none of them involve it being mixed with cement. The presence of asbestos in cement would weaken the final product (concrete, grout, mortar, stucco, or whatever), so there is no reason to deliberately include it in the cement.
