Crushed limestone dust is a waste material from the production of concrete aggregate by crushing quarried limestone rocks. The dust is usually less tan 1% of the aggregate production. Although it is coarser than common cementing materials such as as Portland cement, coal fly ash and ground blast furnace slag, it is fine enough to cause many problems during materials handling and disposal.
Hence the crusher dust and blast furnace slag can be effectively introduced in place of river sand and coarse aggregate with blast furnace slag in concrete mix . Flexural Strength The flexural strength of concrete specimens at 7 days and 28 days are given in table 3.
