Diagonal compressive tests with different mortar bedding

Description

This database presents experimental results from three-course wallettes constructed with hollow concrete blocks. Thirty-three wallettes were tested under diagonal compression with different mortar placements: full and face-shell bedding. The results were processed and presented in two Excel sheets. One sheet contains the characterization results of the component materials: blocks and mortar, while the other includes the results of the tested wallettes. The Excel sheets present shear stress vs angular deformation graphs and the filtered and summarized results. Additionally, photos from the tests are provided to illustrate the failure modes of the specimens.

Steps to reproduce

To reproduce the data, follow these steps: • Acquire blocks, primarily from the same lot, after calculating the required number of units. • Acquire materials for preparing the mortar and capping. • Characterize the blocks through compression and axial tension tests. • Determine the mortar mix necessary to achieve the strength required by standards. • Construct the wallettes according to the regulations of each country, with the mortar placed in full and face-shell bedding. • From each batch of constructed wallettes, obtain mortar samples for characterization in tension and compression. • Wait 28 days. • Prepare the specimens for diagonal compression testing. Apply capping with plaster and attach LVDTs. • Test the specimen with a 100-ton hydraulic jack, using a data acquisition system to collect stress, displacement, and load data. • Process the results in Excel and create the graphs.
