Accelerated test methods are most suitable since sulfate attack is a long term process. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Mortar bars made using mortar described in Test Method C 109/C 109M are cured until they attain a compressive strength of 20.0 ± 1.0 MPa (3000 150 psi), as measured using cubes made of the same mortar, before the bars are immersed. ASTM C1012 standard test method  to measure the expansion of mortar bar specimens, although efforts to reduce specimen size and focus on the evaluation of pastes as opposed to mortars have progressed in recent years [11,12].
