The volumetric mixer varies in capacity size up to 12 m 3 and has a production rate of around 60m 3 an hour depending on the mix design. Many volumetric concrete mixer manufacturers have innovated the mixer in capacity and design, as well as added features including color, multiple admixes, fiber systems, and the ability to do gunite or shotcrete.
Stephen invented a self-discharging motorized transit mixer that was the predecessor of the concrete mixer truck and applied for a patent in 1916. [2] However, the patent was rejected in April 1917 by the patent office because it was believed that a truck could not support the weight of a concrete mixer on top of it. [5]
It was less expensive than a cement truck dedicated to only carrying cement and allowed the trucks used to continue to be adapted for other things. [2] Concrete mixers have continued to advance. Recently, research detailing a forward simulation model of an energy-saving concrete mixer using hydraulic technology was released based on Matlab ...

[2] WILD is free to university undergraduate students and has rooted itself in the campus culture as an exciting time of the semester for students of the university to get together ...
Cement hydration and strength development mainly depend on two silicate phases: tricalcium silicate (C 3 S) , and dicalcium silicate (C 2 S) . [1] Upon hydration, the main reaction products are calcium silicate hydrates (C-S-H) and calcium hydroxide Ca(OH) 2, written as CH in the cement chemist notation. C-S-H is the phase playing the role of ...
