The first step in making concrete is to prepare the cement. one type of cement, pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. to make it, the raw materials are crushed and ground into a fine powder and mixed together.

The finely ground raw material or the slurry is fed into the higher end. at the lower end is a roaring blast of flame, produced by precisely controlled burning of powdered coal, oil, alternative fuels, or gas under forced draft. as the material moves through the kiln, certain elements are driven off in the form of gases.The most common way to manufacture portland cement is through a dry method. the first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. after quarrying the rock is crushed. this involves several stages. the first crushing reduces the rock to rotary kiln.

May 14, 2020 cement acts as the binder between aggregates fine and coarse rocks in the formation of concrete. while cement makes up only a small percentage of the mix approximately 12 percent by volume, it is almost exclusively responsible for the resulting co 2 emissions. in the cement-manufacturing process, raw materials are heated to high temperatures in a kiln in a fuel-intensive rotary kiln.
