How Concrete is Made - cement.org

Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete. The strength of the paste, in turn, depends on the ratio of water to cement. The water-cement ratio is the weight of the mixing water divided by the weight of the cement.

Paste – The Future of Tailings Disposal?

Paste backfill is always placed cemented and the optimum slump that minimises transportation pressure losses and maximises strength gain is often found between 150 and 200 mm. Pumping of paste for backfill is rare but for surface disposal, where cement is not routinely added, pumping makes up a very important part of the paste system.
