A review of using marble powder wastes on self-compacting concrete
Aisha Gumma Jebril

The topic of replacing cement by materials with cementitious properties and less harmful to the environment has caught the attention of a large number of researchers in the concrete production sector, satisfactory results were achieved in this regard, especially cement replacement with fly ash, silica fume, limestone and other pozzolan materials, both in normal concrete or self-compacting concrete. Despite the world's interest in recycling industrial waste, the researches about the use of marble powder in self-compacting concrete is very little comparing with other materials wastes, researches agree that it is difficult to produce self-compacting concrete without additives that reduce water content, Whereas, many studies have proven the success of high rang water-reducing admixtures in giving self-compacting concrete its properties required and which depends on its composition on Polycarboxylate, (as well as mineral additives) pozolan or inert materials to improve the gradation of the grain which is important to ensure the homogeneity of the self-compacting concrete. this paper present the main recent studies on the effect of marble waste on self-compacting concrete properties, Due to the need for some facilities to use self-compacting concrete, and the fact that they require a high content of fine materials for high fluidity without segregation or bleeding.
