Realistic Choice

The elementary scattering theory of Rayleigh and Born is extended to account for effects of finite absorption and of sample geometry including boundary refraction. Examples of the procedure are given for several scatterer configurations and results compared with those of the Rayleigh-Born procedure. It is shown that for a realistic choice of tissue parameters these effects modify the Rayleigh-Born results by factors of the order of 10 percent or less provided observations are made over a suitably limited range of angles about the backward direction.

Cylindrical Samples

Late expansions due to alkali-silica reaction were observed in field samples for some aggregates and supplementary cementing materials (SCM) combinations despite meeting the 2-year expansion criterion of the concrete prism test. This fosters a research into the effect of sample geometry and aggregate reactivity on alkali leaching and expansion of lab samples. Larger samples showed less leaching compared to standard prisms. Cylinders of 100 mm-diameter showed higher expansion than 75 mm-standard prisms; however, both sample shapes showed similar expansions for one tested aggregate when used with SCM. Alkali leaching from concrete samples and alkali release from some aggregates could lead to cylindrical samples having higher expansion and better correlation to field samples compared to standard concrete prisms.
