Fly ash is the non-combustible part that is finer than bottom ash and escapes the furnace with the flue gases.Īs clinker and ash mainly consists of silicon dioxide, magnesium dioxide and other non-combustible minerals naturally found in coal, incorporating these minerals into a construction block became a cheap and useful way of using the waste products from power stations and other furnaces.

As usual the names vary depending on what English speaking country you are in. ![]() Both concrete blocks and cinder blocks use Portland cement to bind the aggregate together but whereas concrete blocks use between 60% to 75% of fine crushed stone and sand, a cinder block will use the same amount of coal cinders or ash. In our guide you will find all the details in regard to the uses of cinder block, the cost of it as well as up to 4 free contractor quotes.Ī cinder block is a man-made building block made from a special type of concrete. ![]()
