From Ref. 34. 6 The pessimum proportion model showing the effect of a high alkali removal rate. From Ref. 34. alkali to reactive silica in order to produce expansion and cracking of a mortar specimen in a minimum time period. Such a ‘critical ratio’ will depend on the nature of the reactive material in the mortar or concrete and the mobility of pore fluids within the sample. This mobility will, of course, depend on the porosity and permeability of the concrete, and this in turn will depend on a number of factors, but perhaps most important among these will be the watercement ratio.

However, in general, dissolution of the ash, which occurs over a few months or years, provides the same alternatives between release, retention in the hydrate phases or partition between the two. The alkali-binding power of the hydration products, and the influence of blending agents, will be discussed subsequently. 5 Some chemical and mineralogical features of aggregates SiO 2 comprises about 65% by weight of the accessible portions of the earth’s crust. Not surprisingly, therefore, SiO2 occurs both ‘free’, that is as a solid crystalline oxide from which other essential elements are absent, as well as in silicates, in which silicon and oxygen are combined with other elements, of which aluminium, magnesium, calcium, potassium, sodium, iron and hydrogen are the most important.
