  • Sampling concrete by too small elements; what should we do to get reliable information?
    Stroeven, Piet ; Guo, Zhanqi
    Macroscopically heterogeneous materials like concrete are generally sampled bytoo small, i.e., subrepresentative elements that can be either of 2D (section images) or of 3D nature (specimens). Based ... on scientific notions, like stochastic heterogeneity and structure-sensitivity, which are at the veryheart of materials science and stereology, the paper demonstrates biases in obtained information to be generally inevitable when derived from such sub-representative designs. Only reliable comparison studies can be performed under the condition that the linear size of samples and of minimum structural dimensions (resulting from observation resolution) are maintained as fixed proportions of the relevant representative area and/or volume elements. This is demonstrated by three case studies.
