mixture proportioning of concrete Topic

Apr 22, 2021  Mixture proportioning refers to selection of the proper amount of ingredients to make a batch of concrete. Selecting concrete proportions involves a balance between economy and requirements for placeability, strength, durability, density, and appearance. The required characteristics are governed by how the concrete will be used and by conditions expected to be encountered at the

Fine Aggregate Affect Concrete Mix Design Sigmatest

How fine aggregate affects concrete mix design. Fine aggregate is a concoction of various materials which are distributed, refined and picked after going through thorough analysis through a sieve test. The aggregate must have the right proportion of course and fine agglomeration, for it to be considered fit for use in construction.
