Prediction of Compressive Strength for Heterogeneous Mortars from Drilling Resistance Data

Prediction of compression strength of ancient mortars through in situ drilling resistance technique

“…Tiano et al [32], Theodoridou et al [33]), while recently it is used for mortars too. Its application on heterogeneous materials is not yet conventionally established due to the irregularity of the drilling profiles obtained: it is still a research argument and many researchers are working on it [34][35][36][37][38][39][40][41][42][43]. In particular, the works of Nogueira et al [41] recently developed predictive models for the definition of the characteristics for low-quality and heterogeneous mortars through correlations among the main statistical indicators of the DRMS results (average, covariance and skewness) and the compressive strength, pointing out the skewness as the most accurate indicator.…”
