Abstract	Microhardness and fracture parameters of several high alumina cement paste systems containing varying proportions of hexagonal and cubic phases have been determined using single edge-notched flexural specimens from each system. Specimens were conditioned and tested at 11% RH in a specially constructed environmental chamber. Data demonstrated dependence of the fracture parameters on microhardness. Effect of morphology and other microstructural features on fracture in HAC paste is also discussed. Some evidence supporting argument for the validity of applying linear-elastic fracture mechanics in studying fracture in brittle cementitious systems is presented.
