CHAPTER 1 COMPONENTS OF CONCRETE
COMPONENTS OF CONCRETE Concrete is made up of two components, aggregates and paste. Aggregates are generally classi! ed into two groups, ! ne and coarse, and occupy about 60 to 80 percent of the volume of concrete. The paste is composed of cement, water, and entrained air and ordinarily constitutes 20 to 40 percent of the total volume.

Low carbon multi-component cements for UK concrete
Project description: In today's cement and concrete industry, the carbon impact of cement is commonly reduced by substituting the primary component – Portland cement clinker – with lower carbon secondary components such as fly ash (a waste from coal fired power stations), GGBS1(a by- product from iron and steel manufacture) and ground limestone.

Cement clinker - Wikipedia
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
