Creep in compression measured on prisms loaded in hydraulic pressure rigs. Creep in tension measured on necked specimens under dead weight loading.

This Part of BS 6319 describes methods for the determination of the creep of specimens of polymer and polymer/cement mortars. Creep in compression is measured on rectangular prisms and creep in tension on necked specimens having a maximum aggregate size of 2.4 mm.

The prime objective of the methods is to provide comparative data on materials in order to establish whether or not creep is likely to be significant in the intended application. The methods provide an estimate of creep strains within ± 10 % of the absolute value under the particular environmental conditions in which the test is conducted. For comparative purposes, it is necessary to control the temperature to within ± 2 °C of the specified temperature but control of humidity is not essential.

NOTE For specific applications where a higher level of accuracy is required, additional requirements for measurement of load, achieving axiality and environmental conditions should be agreed before testing commences.
