WebJan 1, 1996 · This test determines the ratio of cementitious components to sand in the mortar mix. It should be performed in conjunction with A5 in ASTM C 780, which is the test for mortar water content. These tests can be performed on any fresh mortar, either out of the mixer or off the board. WebNov 5, 2009 · The bond wrench test determines the flexural bond strength of masonry by subjecting a masonry prism to an eccentric load which ‘wrenches’ the top brick from the rest of the assembly, allowing to test several mortar joints in a single prism.
WebFeb 11, 2024 · This type of test is called bond-wrench test. The Fig. 7.9 shows a schematic representation of ASTM bond-wrench test set-up and a simplified bond-wrench test set-up (called modified bond-wrench test). The testing procedure involves mounting a prism and fixing it at the base. WebFigure 5: Bond wrench test apparatus and joint failure 2.5. Masonry tensile bond strength (Splitting test) Because the failure of the wallettes also involved some vertical splitting, for later modelling purposes, it was also useful to determine the transverse strength of the masonry composite.
