Water–cement ratio Wikipedia
Water–cement ratios of to are more typically used. For higherstrength concrete, lower ratios are used, along with a plasticizer to increase flowability. Too much water will result in segregation of the sand and aggregate components from the cement paste .

water in a cubic yard and divide it by the weight of cement. Durable concrete mixes usually need a w/c ratio of .50 or less (lower is better). So, to translate, that would mean a mix with 500 lbs of cement shouldn't have more than 250 pounds of water or about 30 gallons. Photo courtesy of Portland Cement Association. info 2/14

Concrete and Mortar Guide Mix Ratios, Curing Times and More
Sep 01, 2018· For example, a simple sand and cement mix should be at least 3 part sand (the aggregate) to one part cement. A strong concrete mix would be something like 1:3:5 (Cement, Sand, Coarse Gravel). In this case, both the sand and gravel are the aggregate. In premix concrete, the aggregate is already mixed with the cement.
