The cement-bone interface was more compliant under tensile than compressive loading at the 0° loading angle only (p=0.024). The coupled transverse to axial compliance ratio, which is a measure of the coupled motion, was small for laboratory prepared (0.115±0.115) and postmortem specimens (0.142±0.101).
For the axial compression tests of the concrete blocks, a thin layer of cement plaster to correct the imperfections of settlement and of the materials was used. This procedure reduces defects that can generate stress concentrations. Reaction walls were used to test the structural masonry, according to the Brazilian Standard NBR 16522 [23].For the …

Even if the cement is not low-alkali cement (below 0.60%), the amount is important for three reasons: Air-entraining agents generally produce more air as the alkali content goes up. Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content.
