AUTOCLAVED AERATED CONCRETE FROM SLATE WASTE. PART 2: SOME PROPERTY/POROSITY RELATIONSHIPS

Another paper provides some property/density relationships for a series of experimental slate-based autoclaved aerated concretes which cover a wide range of densities. The present paper goes on to discuss the corresponding property/porosity relationships for the same series. Porosity is characterised by the solid/pore volume ratio, vs/vp, which stems from a very simple physical model of the materials. Regression analysis indicates that compressive strength, flexural modulus and strength, as well as fracture characteristics, can be regarded as linear functions of vs/vp within a reasonable degree of approximation.
