Cement, concrete the circular economy
The cementmaking process can be divided into two basic steps: ssClinker (the main constituent of cement) is first made in a kiln with gas up to 2000°C, which heats raw materials such as limestone (calcium carbonate) with small quantities of other materials ( clay) to 1450°C. During this process, known as calcination, the calcium carbonate

Quantity Of Cement, Sand, Aggregates For 1000 sq ft Slab
To calculate the quantity of cement, sand, and aggregates required for a flat slab first we need to calculate the volume. Area of flat slab = 1000 =93 sq. m. The minimum thickness provided for the slab is 150 mm. ( According to IS 456) 150 mm = metres. Hence Wet volume = Area of slab x Thickness of slab.

Cement Types
The heating that occurs in the kiln transforms the raw materials into new chemical compounds. Therefore, the chemical composition of the cement is defined by the mass percentages and composition of the raw sources of lime, iron, silica, and alumina as well as the temperature and duration of heating. It is this variation in raw materials source and the plantspecific .

LCA of cement
The main component of cement is called clinker. Clinker consists of cinder lumps formed by heating limestone, bauxite, and iron ore sand to 2,770 o Fahrenheit. The production of clinker is very resource intensive. Producing one ton of clinker requires an energy input of between MJ and approximately tons of raw material. [2]
