Recommendations for Manually Batching Concrete? - Structural

All of the batching is going to be done without stationary mixers, and all done manually. Does anyone have any recommendations for ratios of materials to achieve 3000psi and 4000psi concrete in these conditions? Are there any other special circumstances we need to account for while manually batching? Thank you for any help given.

Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...
