concrete.

Overall

, the key points to mention are that

cement

production is complex and consists of several stages, and that concrete is made from four fundamental elements in precise proportion. Regarding

cement

, the procedure is initiated with raw materials

such

as Limestone and clay being crushed into powder through a crusher,

then

the powder is put into a mixer and passed through a rotating heater where heat is supplied constantly.

In addition

, the material still requires one final process, which is to ground it, package it into prepared bags, and

then

deliver it to the market. After the ingredients are transferred to the concrete-making site, a combination of 15%

cement

, 10% water, 25% sand, and 50% small stones are combined together in a mixer and blended so that concrete is

finally

made out.
