SCI Engineering’s Construction Materials Testing Team was thrilled to once again play host to campers from the Society of American Military Engineers (SAME) STEM Camp to our O’Fallon, Illinois office this past week. These next generation scientists and engineers had the opportunity to get some hands-on experience learning about aggregate base and how a slump tests indicate concrete’s ability to flow. SCI President Scott Harding and Construction Field Manager Mike Lajoye lead the mentoring/teaching group. The campers competed in a concrete mix design challenge while they were here. Each group had the challenge of coming up with their own mix design for concrete. They had to work together to properly measure, weigh and mix concrete and then cast two 6×12 cylinders. These cylinders will cure at SCI for 4 days, at which time the campers will return to watch their cylinders be crushed. This will determine who made the strongest concrete mixture. SCI is thrilled to help these budding engineers receive real world, hands on training.
