There are 2 chief aspects of the manufacturing process: First
Readymix concrete (RMC) is a type of concrete which is manufactured in a cement factory, or specifically known as the batching plant, according to a given set of proportions, and then delivered to a work site, by truck mounted with mixers. This results in a precise mixture, allowing specialty concrete

Magazine / Archive 20092010 / Precast Concrete Manufacturing and the Environment July 28, 2010 1 Comment As a building material, precast concrete has an edge over other materials in many sustainability practices, but a precaster can be environmentally friendly in other
5.1 Overview of the Hydration Process. The hydration of cement can be thought of as a twostep process. In the first step, called dissolution, the cement dissolves, releasing ions into the mix water. The mix water is thus no longer pure H2O, but an aqueous solution containing a variety of ionic species, called the pore solution.
Aug 30, 2012 · Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference. NOTE:
Environmental and manufacturing conditions at a precast concrete plant are easily monitored. The production of precast concrete elements takes place under controlled conditions in enclosed factories. This makes the control of manufacturing, waste, emissions, noise levels, etc. easy compared with the same processes at a building site.
The mixing operation consists of rotation or stirring, the objective being to coat the surface the all aggregate particles with cement paste, and to blind all the ingredients of the concrete into a uniform mass this uniformity must not be disturbed by the process of discharging from the mixer.
