Successful cement production starts with the raw materials and the methods needed to process it. Vertical mills grind the raw powder to the correct fineness before it is subsequently burned in the rotary kiln to produce clinker.
Portland cement is the strongest most cost effective material to use. Short of coming up with a whole new binder, ie a polymer, epoxy, nothing is going to change. Go after the other 95% of CO2 emissions.
A cement is a binder, a substance used for construction that sets, hardens and adheres to other materials, binding them together.Cement is seldom used on its own, but rather to bind sand and gravel together.Cement is used with fine aggregate to produce mortar for masonry, or with sand and gravel aggregates to produce concrete.
Scientists estimate that the global cement industry accounts for around 5 percent of the world's carbon emissions, and more than half of the world's cement production capacity is based in China.
Cement production is either "wet" or "dry", depending on the water content of the material feedstock. The wet process was the original rotary kiln process developed at a time when material handing of slurries was more developed than those of dry powders.

Estimating the cost of new concrete involves much more than the price of concrete per yard (or meter).There are many variables to consider, such as surface prep, formwork, reinforcing materials, and finish work, plus the cost of the ready-mix concrete, that will add up to the total price of the job.
The CO 2 emission from the concrete production is directly proportional to the cement content used in the concrete mix; 900 kg of CO 2 are emitted for the fabrication of every ton of cement, accounting for 88% of the emissions associated with the average concrete mix.
