This paper studies the early mechanical properties of artificial sand concrete, we found by comparison with natural sand concrete that the slump of artificial sand concrete were increased by 85%, and the strength 0f 16h and 1d and3d were increased by % and 20% and 11%. Therefore, artificial sand can significantly improve the workability of concrete mix, improve the early strength of concrete.

An artificial neural network (ANN) is presented to predict the workability of self compacting concrete (SCC) containing slump, slump flow and Vtest. A data set of a laboratory work, in which a total of 23 concretes were produced, was utilized in the ANNs study. ANN model is constructed, trained and tested using these data.
