✦ Synopsis

Considering cement based composites as chemically bonded ceramics (CBC) the consequent strength development with age is essentially a constant volume solidification process, such that the hydrated gel particles fill the space resulting in the compatible gel space ratios. Analysis has been done of the extensively used graphical method of mix design (British method of mix design) i.e., the relation between the compressive strength and the free water -cement ratio. By considering the strength (S) at w/c 0.5 (S, J as the reference state to reflect the synergetic effects between constituents of concrete a generalized relationship obtained is of the form {S/S, 5} = a + b { 1 /(w/c)}.
