The concrete mix design was proportioned to have a 28-day compressive strength of 30 MPa. The selection of this strength is based on industrial norms for normal structural concrete used in Qatar. The water-to-cement ratio (w/c of 0.58) was kept constant for all of the nine mixes in orde...
Additionally, it involves proper mixing, placing, and curing, and application of other production processes needed to give a structurally and environmentally stable system. In order for the concrete user and producer to take maximum advantage of the potential of such a variable material, it is ...
