Cement concrete and other cement-based composites find wide application in the construction industry. The manufacturing of cement releases a large amount CO2, so use has become major area environmental concern. Attempts have been made to minimize quantity con- crete by replacing it with supplementary cementitious materials. Geopolymer is one those potential candidates for alternative mate- rial...

The current study focuses on two main goals. First, with the use of construction and demolition (C&D) of building materials, a new aggregate was produced and it was utilized for green concrete production. The compressive strength test confirmed the good function of C&DW aggregate concrete. This concrete did not show significant differences with natural sand concrete. Second, Backpropagation neu...
