The Mix Design team went to the lab on Friday to become familiar with mixing concrete for practicality purposes. The team made a progression of three separate mixes in 3 cubes each. We based all three of our mixes using the standard 3 part stone, 2 part sand, 1 part portland cement, and water formula. Mix 1 consisted of stone aggregates with a wide range of sizes taken from the soils lab. For Mix 2, we used smaller aggregates by pouring the stone through a 3/8″ sieve. For Mix 3, we crushed more stone and then run it through the 3/8″ sieve. During this mix, we used a blender to mix all 3 materials into a consistent mix and added enough water in an attempt to balance the strength and workability. All three mixes were poured into the cube forms in a few rodded layers. Finally, we covered the forms with wet burlap to contain the moisture in the concrete. We will wait 2 weeks for the concrete to cure and follow up with testing its strength and comparing the properties of the three different mixes.
