A batch of concrete has 45 gallons of water and 900 lbs of cement. The water to cement ratio can be calculated as. Scientific Online Calculator . 11 13 .

Learn MoreApr 23, 2018 · Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield. Use the following yields per each bag size: 40 pound bag yields .011 cubic yards

Learn MoreConcrete yield is an important consideration on many jobs. An engineer may compute the number of cubic yards of concrete needed for a 500,000 square foot floor, and the ready mix producer may deliver the concrete in complete accordance with the specifications. Yet when the specified number of cubic

Learn MoreCalculate yield by determining the density (or unit weight) of the mix, then check the batch ticket to determine the total weight (or mass) of all the materials that went into the batch. Calculate the yield and air content of the mix by using ASTM C 138, "Standard Test Method for Density (Unit Weight), Yield, and Air Content (Gravimetric) of

Learn MoreHow to Calculate Material Needed. Let's be honest - sometimes the best material needed calculator is the one that is easy to use and doesn't require us to even know what the material needed formula is in the first place! But if you want to know the exact formula for calculating material needed then please check out the "Formula" box above.

Learn MoreNov 21, 2018 · Product yield measures the output as an indicator of productivity, efficiency and product quality for manufacturers. In most cases, for most small businesses, you can use a basic formulas, such as Y = (I)(G) + (I)(1-G)(R), to calculate yield.

Learn MoreEnter the number of bricks (8" x 2" x 4") or blocks (8" x 8" x16") in the box below that you plan to use for your project. The calculator will then tell you the number of bags you need based on the different size of bags we carry. This calculator is based on a 3/8" mortar joint.

Learn MoreBased on that value, you can find the percentage yield by using the ratio of the actual yield and the theoretical yield. The formula for calculating the percent yield is: Percentage yield = mass of actual yield ÷ mass of theoretical yield × 100%. Let’s assume that you obtained an actual yield of 8.50 grams. Then, the percent yield would be:

Learn MoreThe concrete calculator should help you get started on the planning phase of your project. Be sure to discuss with your sales rep when you are ready to order your concrete. To use the calculator: Choose units of measure: English or Metric. Enter the width, length, and thickness of the project.
