The environmental impact of concrete, its manufacture and applications, are complex.Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete.
High density aggregates are used to form heavyweight concrete. They are used for when high strength, durable concrete structures are required – building foundations or pipework ballasting, for example. Classification of aggregates based on: Geographical Origin. Another way to classify aggregates is by their origin. You can do this with two ...
concrete. Concrete washout. After concrete is poured at a construction site, the chutes of ready mixed concrete trucks and hoppers of concrete pump . trucks must be washed out to remove the remaining concrete before it hardens. Equipment such as wheelbarrows and hand tools also need to be washed down. At the end of each work
