Abstract
The test method consists of the following steps: <SL> <LI>1. A steel fibre is placed on a flat perpex plate. <LI>2. The steel fibre is coated with a thin layer of the required cement matrix. <LI>3. The coated fibre is exposed to a hostile environment stored in an appropriate environmental chamber. <LI>4. Prior to testing the coated fibre is embedded into a rapid strengthening cement or a cold cure adhesive in a dogbone pull-out arrangement. </SL>
Description
1 2356058 BOND DURABILJTY TEST OF SFRC This invention relates to steel
fibre reinforced concrete (SFRC).
Steel fibre reinforced concrete has found several applications in the construction industry but generally these have been confined to less adverse environmental conditions because of a lack of confidence regarding its long-term corrosion resistance. In the splash zone of marine structures for example the superior mechanical properties of SRFC can be of particular advantage but until its corrosion resistance is conclusively established the construction industry will continue to avoid its use in marine applications.
Current laboratory durability tests make use of beam specimens usually tested in flexure which contain large numbers of fibres. These test procedures also require voluminous environmental chambers and accompaning monitoring equipment and are time consuming.
According to the present invention a technique is provided for use as an alternative standard durability test method in industrial laboratories. The test specimen is easy to make, inexpensive (since only a fraction of fibres is required compared to the num of fibres used in current test procedures), able to rapidly predict percentage changes in fibre/cement shear bond strength and requires environmental chambers of minimal sizes. It consists of a two-stage single-fibre pullout test where a fibre coated with a thin layer of the cement matrix material is embedded into a dogbone pull-out arrangement after exposure in appropriate media.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which:
Figure I shows the dogbone test arrangement.
2 Thu fibre is placed on a flat plate and a thin fdm of the required cement matrix material is applied to it.
The coated fibre is then stored in appropriate environmental chambers.
Prior to testing the coated fibre 16 is removed from the storage environment, dried using a cloth and embedded centrally into a rapid strengthening cement 15 or a cold cure epoxide adhesive 15 in a dogbone, pull-out affangement, as Fig.1 shows.
