	The characteristics of concrete are determined by the aggregate or cement used, or by the method that is used to produce it. The water-to-cement ratio is the determining factor in ordinary structural concrete with a lower water content resulting in a stronger concrete.

−	This, however, reduces the workability (and pumpability) of the concrete, which can be measured using the slump test. The grading, shape, texture and proportion of aggregate can also have a similar ~~affect~~. If a particularly strong concrete is required, the amount of aggregate can be reduced in relation to the cement. However, cement is a significant cost factor, and increasing its proportion in the mix will increase the overall price.	+	This, however, reduces the workability (and pumpability) of the concrete, which can be measured using the slump test.

	When making concrete, admixtures can be used to alter the characteristics of the concrete. For example accelerators can be used to make it set more rapidly, retarders to make it set more slowly, superplasticisers to reduce the water content etc.		When making concrete, admixtures can be used to alter the characteristics of the concrete.

	Formwork is a temporary mould into which concrete is poured and formed. Traditional formwork is fabricated using timber, but it can also be constructed from steel, glass fibre reinforced plastics and other materials.

−	Formwork may be; temporary, re-usable, or stay-in-place. There are also a number of proprietary systems such as those used to support vertical formwork while concrete cures, consisting of a series of tubes and ties.	+	Formwork may be temporary, re-usable, or stay-in-place.

		+	The UK cement and concrete industry has published a Roadmap to Beyond Net Zero, setting out a pathway to net-zero carbon concrete across its lifecycle by 2050, including through lower-carbon cement chemistries such as limestone calcined clay cement (LC3), increased use of GGBS and PFA in place of Portland cement, and carbon capture at cement works.
