What are dense concrete blocks used for?
Dense blocks are usually made from cement, fine aggregate and course aggregate. They can be produced in a range of crushing strengths and tend to be used for structural purposes, such as foundations and load-bearing walls. They generally have poor thermal insulation and readily absorb water, but have good thermal mass.
Why is concrete grey?
The natural color of concrete is gray because the color of the cement used to make it is typically gray. … In cement manufacturing, Iron Ore is used as one of the main constituents, and Iron Ore is black in color, so when it is combined and melted with the other materials it tints the cement gray.
