Packing calculations applied for concrete mix design

Proceedings Creating with Concrete, May 1999, University of Dundee 1 PACKING CALCULATIONS APPLIED FOR CONCRETE MIX DESIGN M. Glavind E. J. Pedersen Danish Technological Institute, Denmark ABSTRACT. When selecting a concrete mix design, it is always desirable to compose the aggregates as densely as possible, i.e. with maximum packing.

[PDF] Concrete Mix Design By Packing Density Method ...

Packing density is new kind of mix design method used to design different types of concrete. To optimize the particle packing density of concrete, the particles should be selected to fill up the voids between large particles with smaller particles and so on, in order to obtain a dense and stiff particle structure. Higher degree of particle packing leads to minimum voids, maximum density and ...

Jul 01, 2009  The concept of particle packing has already been applied to the aggregate proportioning for optimum concrete mix design. Early in the 1960s, Powers had suggested that a concrete mix may be considered a mixture of aggregate particles and cement paste. He conceived that the paste trapped inside the voids in the bulk volume of aggregate is not ...

Jul 27, 2012  For the design of defined-performance concrete, predicting the material properties of concrete becomes more and more important. To be able to select the right type of fillers and control the water demand in such mixtures, an extension to the compressible packing model was developed to optimize the particle packing of aggregates as well as powders in concrete.

Design of Normal Concrete Mixtures Using Workability ...

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 properties.
