Tutor description

Several mixtures of cement, aggregate, sand and water were mixed at different ratios to workability and compressive strength. The dry materials of the mixture were mixed and water was gradually added, the mixture was then placed in a cube and allowed to dry forming the concrete testing cube. Each of the four blocks containing different compositions of each material were then placed in a compressive testing machine and when each cube yielded, results were taken.

Concrete LabApplied Engineering science report.Michael Connor B00240227Part A: Several mixtures of cement, aggregate, sand and water were mixed at different ratios to workability and compressive strength. The dry materials of the mixture were mixed and water was gradually added, the mixture was then placed in a cube and allowed to dry forming the concrete testing cube. Each of the four blocks containing different compositions of each material were then placed in a compressive testing machine and when each cube yielded, results were taken. Effect of water content on workability of fresh concrete:As more water was added to the dry mixture, it became easier to work with but we had to be careful not to add to much water or this would weaken the concrete and possible ruin the mixture. If you wanted to further test a mixture, a slump test would be the best to evaluate workability.
