Dataset for the results of fibrous plaster tests: Pull-off samples tensile tests.

Fibrous plaster tests have been conducted - fibrous plaster consists of gypsum plaster, hessian fibres and often a steel wire. It has been used for ceilings and as decorative features in theatres, civic buildings and private residences.

The data concerns the tests conducted to date concerning fibrous plaster pull-off test samples. Samples were made and tested in the laboratories of the University of Bath. Tensile tests were performed on 'pull-off' samples where an attached cylinder was pulled from a base plate to test the adhesion of the cylinder material to the base plate material.

Collection date(s):

From 1 October 2020 to 30 September 2022


Data collection method:

Pull-Off: Twelve specimens each from multiple sample groups which consisted of a new cylinder element attached to a base plate, and the cylinder pulled off the base plate using tensile loading on a bespoke test rig. Sample groups included both hessian and quadaxial glass fibres, gypsum plaster, jesmonite and aramid gel. Bases were both clean and 'dirty' - with historic mould applied.

Technical details and requirements:

Pull-off: 100 kN capacity test rig Dartec Universal Testing Machine, displacement controlled tensile loading at 0.2 mm/min.

Additional information:

Data is available in Microsoft Excel spread sheets and Origin software output.
