A typical concrete machine mixer uses a revolving drum to mix the components The compressive strength of concrete depends on the aggregate grading aggregatecement ratio as well as the watercement ratio The freshly mixed concrete should be workable to be properly placed and the hardened concrete needs to be durable A typical process of manufacture consists of three stages grinding a mixture of limestone and clay or shale to make a fine rawmix see Rawmill heating the rawmix to sintering temperature up to 1450 C in a cement kiln grinding the resulting clinker to make cement see Cement mill In the second stage the rawmix is fed into the kiln and gradually heated by contact with

When making your own concrete its important to use the correct concrete mixing ratios to produce a strong durable concrete mix Some basic mixing ratios for concrete are 123 133 124 These mixing ratios are based on the proportions of cement sand stone in that order The ratio you use will depend on what psi strength you need Sep 16 2019 The process looks a bit like shaking a snowglobe as it produces a flurry of suspended white particles inside the glass container as the lime precipitates out of the solution While the technology is simple and could in principle be easily scaled up a typical cement plant today produces about 700000 tons of the material per year
