|Title:||The use of quarry dust for SCC applications||Authors:||Ho, D.W.S.
|Issue Date:||Apr-2002||Citation:||Ho, D.W.S., Sheinn, A.M.M., Ng, C.C., Tam, C.T. (2002-04). The use of quarry dust for SCC applications. Cement and Concrete Research 32 (4) : 505-511.

This paper deals with the utilisation of alternative materials, such as quarry dust, for SCC applications. Results from rheological measurements on pastes and concrete mixes incorporating limestone or quarry dust were compared. It was found that the quarry dust, as supplied, could be used successfully in the production of SCC. However, due to its shape and particle size distribution, mixes with quarry dust required a higher dosage of superplasticiser to achieve similar flow properties. © 2002 Elsevier Science Ltd.
