What is the ratio for fly ash as the cement replacement in concrete?
Replacement of cement with flyash in concrete is 20-35 % by weight for normal structures. however for special structures like dams the replacement levelscan be increased to up to 70 %. (where flyash must be ISI standards compatible or any such standards) This replacement also reduces water requirement by 2.5 % for every 10 % replacement of flyash used.
What are the ingredients for concrete solid block?
Concrete block is made from Portland Cement, water, sand and aggregate. The aggregate may be in the form of flyash or cinder from burnt coal.
Can fly ash be used in reinforced concrete and prestressed concrete?
There are experimental results showing that the flyash can be used up to 30 % as a cement replacement material. Some up to 80 % flyash has certain properties and it can be used some percent to the concrete mix as a admixture.. Proper trial mix and test shall be carried out for required strength and durability..
