Dec 18, 2014· A magnified piece of Roman concrete consisting of lime, volcanic sand, and rock ( Wikimedia Commons ) It isn't just that Roman concrete is more lasting. It is also not as bad for the environment in the manufacturing of it because the mix only needed to be heated to 900 Celsius as opposed to the 1,450 of modern concrete.
Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing ...

CONCRETE QUIZ 1. Distinguish between cement and concrete. Cement is a component of concrete. Cement and water make the "glue" which holds concrete together. Name at least three items you have encountered today which are concrete. Answers will vary. What are the major ingredients for concrete, and what role do they play?
Cement is the binding element in both concrete and mortar. It is commonly made of limestone, clay, shells, and silica sand, with limestone being the most prevalent ingredient. These materials are crushed and combined with other ingredients (including iron ore), and then heated to about 2,700 F.
Concrete dust released by building demolition and natural disasters can be a major source of dangerous air pollution. The presence of some substances in concrete, including useful and unwanted additives, can cause health concerns due to toxicity and (usually naturally occurring) radioactivity.
