About

Here is a list of the items on this site.

‘CRT paper’ is a paper given at the 2008 Transportation Systems Workshop in Phoenix, AZ. It discusses the concrete prism test (CPT) for alkali-silica reactivity.

‘CPT Precision’ is a visual representation of the implications from the Precision and Bias statement in ASTM C1293.

‘Constant CV’ is a blog about implications of test methods whose results follow a trend of constant coefficient of variation.

‘C1778 Figure 3’ is a continuation of the blog about ‘Constant CV’ – it is planned to develop it into a similar type ‘blog’ – it picks up from the previous and discusses precision implications of Fig. 3 in ASTM C1778

‘MATEC Paper’ is a paper given by Benoit Fournier, et al, about outdoor storage sites around the global. I explore one set of blocks with very highly reactive aggregate and the local temperature effects on the expansions.

‘AMBT 1’ is some rough work done exploring the use of the drc package in R to do some curve fitting with AMBT results (accelerated mortar bar testing).
