Fine Aggregate - Its [6 Properties Role in concrete]

2020-4-12  Fine Aggregate. In concrete or mortar, the aggregate is a granular material, it is called fine aggregate when the particles of granular material are so fine that they can pass through a 4.75mm sieve. To increase the volume of concrete it is used in the construction industry and is cost-saving material.

USE OF BOTTOM ASH AS FINE AGGREGATE IN

2021-2-27  Thus, to increase the speed of construction, enhance green construction environment we can use lightweight concrete. Uses and applications of bottom ash as fine aggregate can reduce the cost of construction materials and also it is useful in environmental protection. Bottom ash used as fine aggregates replacement enables the large utilization of waste product. Even a small quantity of bottom ash used in mass concreting work results in reduction in cost and efficient as well as eco-friendly disposal of bottom ash. Bottom ash has been a resource that has been wasted. This material has worthy property to make it suitable for construction. Though its replacement for sand in concrete in high percentage does not show improvement in strength significantly, its replacement in lesser quantities for a big construction marks it significance. Large quantities of bottom ash have been dumped into land. Such a material can be used in replacement of sand in concrete to make it useful in a better way. This decreases land pollution and makes it eco-friendly. This type of replacement in heavy budget makes it economical. Bottom ash can is effectively used along with plasticizers in considerable amount to improve the strength of concrete. Bottom ash
