Characteristics of SCC with Fly Ash and Manufactured Sand [PDF]
IOP Conference Series: Materials Science and Engineering, 2016 Self compacting concrete (SCC) of M40 grade was designed. The binder in SCC consists of OPC and fly ash in the ratio of 65:35. River sand was replaced by manufactured sand (M-sand) at replacement levels of 20,40,60,80 and 100%. An attempt was made to evaluate the workability and strength characteristics of self compacting concrete with river sand and ...
