Several students were interested in using tempered glassas an additive for a portion of the fine aggregate in a ConcreteMix Design. They stated tempered glass has a high compressivestrength and is an available resource. Their Control mix was to be5 pounds of Coarse Aggregate, 5 pounds of Fine Aggregate, 2.5pounds of cement, and 1.2 pounds of water. Their research idea wasto use 5 pounds of Coarse Aggregate, 2.5 pounds of Fine Aggregate,2.5 pounds of Textured Glass, 2.5 pounds of cement, and 1.2 poundsof water. After the curing process and the compression tests thecontrol mix was 84,000 pounds or 6700 psi; the proposed new mix was69,500 pounds or 5500 psi. Does the new idea show promise (Yes orNo)? Where does one go from here? Explain your answer?
