A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, it then converts that velocity into flow. Centrifugal pumps are made up of two primary components: an impeller and a casing. The rotating impeller generates velocity and the casing converts velocity into flow.

aggregate size, slump, w/c ratio, admixtures, (2) calculation of batch weight, and (3) adjustments to batch weights based on trial mix . Water/cement ratio (w/c ratio) theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio.
Adding Fly Ash to Concrete Mixes for Floor Construction
Nov 29, 2007 · Class C and F fly ashes were used in this research project. Currently, more than 50% of the concrete placed in the U.S. contains fly ash. Dosage rates vary depending on the type of fly ash and its reactivity level. Typically, Class F fly ash is used at dosages of 15% to 25% by mass of cementitious material and Class C fly ash at 15% to 40%.
itself. The force required to pull concrete apart is called its Shear Strength. A conservative value for concrete shear strength is 800 psi. To determine the force required to pullout the bolt separating it at the epoxy to concrete bond, use the following calculation: Force = D x x L x 800 psi Where: F …

Water/Cement Ratio - an overview | ScienceDirect Topics
When concrete is made with w/c ratio higher than 0.42, a very porous hydrated cement paste is generally observed around the coarse aggregate, referred to as the transition zone (Fig. 8.8). On the contrary, in concrete having a w / c ratio lower than 0.42 the cement paste is seen to be very dense and sticks to the coarse aggregates, ensuring a
