Mix designs for concrete block

Determine how much cement is required in the mix. Multiply the weight determined in 5b by the de-sired cement-to-aggregate ratio. Aggregate design batch weight cement-to-aggregate ratio = cement (in lbs.) For example: 1 4,500 lbs. —— = 450 lbs. 10 Step 6: Determine water content. The total amount of mixing water needed to make a high ...
