Aggregate Proportioning And Specifications

17/10/2016  Over the years many different aggregate proportioning techniques have been used to create a concrete mixture. Aggregate can be proportioned by volume, minimum voids, and gradation. Furthermore, a well designed and economical mixture will effectively use the aggregate to reduce the amount of paste in a mixture, but still achieve the required workability, which is called optimized

Important Factors of Proportioning Concrete Mixtures

The proportioning of concrete mixtures is the process of arriving at the right combination of cement, aggregates, water, and admixtures for making concrete according to given specifications, and this process is considered an art rather than a science. Although many engineers do not feel comfortable with matters that cannot be reduced to an exact set of numbers, with an understanding of the ...

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
