To produce a 3000 psi cubic yard of concrete (27 cubic feet) the concrete mixture ratio is: 517 pounds of cement or (234kg) 1560 pounds of sand or (707kg) 1600 pounds of stone or (725kg) 32 - 34 gallons of water or (132L) This mixing ratio will give you a concrete mix that is strong, durable, and good for most concrete projects.

Fig. 18 shows the cement over-batch in dollars from a fairly new concrete plant pro - ducing approximately 200 yd 3 per day. It is clear that for the first month (June 1 to 30) the plant was on an average over-batching about 10 lbs/yd3 of cement. Between June 30 …

The water which could be added to a one cubic yard batch without exceeding the maximum is equal to the maximum minus the actual. Maximum = 35.9 gals/yd3 Actual = 34.2 gals/yd3 Addable water = 1.7 gals/yd3 V. Water Cement Ratio: The water-cement ratio of a batch of concrete is the ratio of mix water (lbs) to cement (lbs).

If the mixed concrete looks like the mix in step 8, it's ready to pour. Otherwise, mix in additional dry mix or water until you get the right consistency. It's tempting to just squirt water into the dry concrete mix with a hose and mix up a soupy batch of concrete. After all, it's quicker and the runny concrete is …
