Question: a. Determine the water-cement ratio of the mix of Problem.
b. What difficulties might result from lowering the water-cement ratio of the mix and how might these be overcome?
Problem: A one-sack trial mix that meets specification requirements has the proportions shown mixer with no overload using an integer number of sacks of cement. Assume that the aggregate is saturated, surface-dry, and allow a 10% overload.
