How to determine concrete yield

S = volume of concrete produced per batch in cubic f e e t ; V d = volume of concrete which the batch was de-signed to produce in cubic yard s . N O TE: A value for Ry greater than 1.00 indicates an ex-cess of concrete being produced, whereas a value less than this indicates the batch to be short of its designed vo l u m e .

method of concrete batching

Volume batching of concrete is a too accurate method for making concrete because of the difficulty it offers to measure granular material in terms of volume. It is a fact that moist sand volume in a loose condition weighs much less

Measurement Of Volume Of Aggregate In Batching

Volume Batching. 1:2:4 generally represents the ratio for M15 concrete. It is generally done by volume batching not by weight. After adding water to the dry mix, the gross volume of concrete reduces from the sum of individual volume of cement, aggregate and sand.

WHAT IS VOLUME BATCHING OF CONCRETE AND HOW IT

2014/04/10 · What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching. Below are mentioned some of important points to remember before adopting volume batching method in […]
