The data set contains the results of a comprehensive investigation of the flexural bond behavior in brick masonry by means of bond wrench tests, with a focus on the influence of the testing procedure. In this context, the study explores the impact of the testing set-up's accuracy and the specimen type on the experimental assessment of the flexural bond strength. Additionally, the data set includes the results of a novel procedure to assess the flexural bond fracture energy.


The data set contains the results of the followings:

(A) Force-controlled set-up entirely operated by hand for in-situ applications.

(B) Force-controlled set-up operated by hand for lab applications.

(C) Computer-controlled set-up operated by controlling the crack mouth opening displacement (CMOD) at the tension side of the tested specimen for lab

applications.

(D) “Standard”, stack-bonded couplets (without head joint).

(E) Running-bonded couplets (with head joint).

(F) Running-bonded wallets (with head joint and courses).


For both force-controlled set-ups, the maximum force registered during the test is reported together with the dimensions of the tested bed joint and weight of the portion of specimen pulled off. For the computer-controlled set-up, the force measured at the relative CMOD and Jack displacement are provided along with the dimensions of the tested bed joint and weight of the portion of specimen pulled off. Detailed pictures of the set-ups and specimens are also included.


Tests were performed on two traditional Dutch masonry types, i.e. calcium silicate brick masonry with a 1:3 (cement: sand proportions by volume) cement-based mortar and clay brick masonry with a 1:2:9 (cement: lime: sand proportions by volume) cement-lime mortar.
