Construction is a cause of global warming but is concrete
Mar 01 2019 · Concrete uses fossil fuels to make cement and sand and gravel for the aggregate. CO 2 is emitted and limited resources are consumed so any use of concrete cannot be sustained on long timescales it is therefore incumbent on people to use as little as possible and to make the very best use we can of the quantities that we use.

Cement A cement is a binder a substance that sets and hardens independently and can bind other materials together. Cements used in construction can be characterized as being either hydraulic or non-hydraulic. Hydraulic cements (e.g. Portland cement) harden because of hydration a chemical reaction between the anhydrous cement powder and water.

Specifications. White Portland cement differs physically from gray cement only in terms of its color. Its setting behavior and strength development are essentially the same as that expected in gray cement and it meets standard specifications such as ASTM C 150 and EN 197. In practice because much white cement is used in pre-cast concrete products it is commonly made to a high-early strength
