Anisotropy and compressive strength evaluation of solid fired clay bricks by testing small specimens
Highlights 461 experiments on extruded, hydraulic press moulded and handmade solid clay bricks. Proposal for a small cubic specimen for the measurement of the compressive strength. Small specimens are tested in the three brick dimensions: length, width, thickness. Anisotropy is quantified in extruded, press moulded, and handmade solid clay bricks. Probabilistic study of the shape effect and comparison with a standardized specimen.
Abstract A study is presented on the use of a non-standard 40 × 40 × 40 mm3 specimen for the experimental measurement of the compressive strength of solid fired clay bricks extracted from existing masonry buildings. The viability of such specimen has been assessed by comparison with experimental results obtained with the standard 100 × 100 × 40 mm3 specimen. The use of the non-standard 40 × 40 × 40 mm3 has two main advantages. First, it significantly reduces the volume of sampled material, which can be severely restrained in architectural heritage buildings. Second, it allows carrying out tests in the three brick dimensions (length, width and thickness), and therefore investigating the anisotropy that clay bricks can exhibit depending of their manufacturing process. The experimental campaign has focused on three different types of solid fired clay bricks, namely mechanically extruded, hydraulic press moulded, and handmade units, with a total amount of 461 specimens. Using the mentioned small cubic specimen, a detailed research on the compressive strength and the anisotropy of different solid clay brick types has been carried out by applying a statistical approach. The experimental results and the statistical processing have shown that the proposed specimen can be utilized for a reliable estimation of the compressive strengths along the three main directions of solid fired clay bricks.
