the mass (e .g. lightweight floors, lightweight concrete) both reduce the structural period, and of course the reverse is also true. However, period depends on the square root of mass divided by stiffnesses, (T =2 π√M/k ) so large changes in mass and stiffness are needed for a significant change in period.

The term concrete refers to a mixture of aggregates, usually sand, and either gravel or crushed stone, held together by a binder of cementitious paste. The paste is typically made up of portland cement and water and may also contain supplementary cementing materials (SCMs), such as fly ash or slag cement, and chemical admixtures (Figure 1-1).

Cement clinker and finished cement are traded internationally. Cement manufacture is a very energy intensive process and results in the production of large amounts of carbon dioxide (CO 2). The carbon dioxide is chiefly produced when the calcareous raw material is calcined to produce calcium oxide. Generally around 0.5 tonnes

cement amounts can be reduced because concrete strength is directly related to the water/cement ratio. Definition of Mineral Admixtures Mineral admixtures include fly ash, hydrated lime, silica fume and ground blast furnace slag. Many of these materials have cement-like properties, augmenting the strength and density of the finished concrete.
