Design of Normal Concrete Mixtures Using Workability-Dispersion-Cohesion Method

The workability-dispersion-cohesion method is a new proposed method for the design of normal concrete mixes. The method uses special coefficients called workability-dispersion and workability-cohesion factors. These coefficients relate workability to mobility and stability of the concrete mix. The coefficients are obtained from special charts depending on mix requirements and aggregate ...

Concrete Mix Design Procedure and Example IS456

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

Concrete Compressive Strength - an overview

Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 10,11 In a concrete having a water/cement ratio lower than 0.42, hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42, very fine cement particles can be fully hydrated but only the surface of the coarsest ones ...
