Abstract (en)

Expanded polystyrene (EPS) slabs were tested to determine their strength and the effects of creep strain under compressive stress. The results were statistically analysed based on long-term experiments between 65 and 2034 days. The analysis shows that it is possible to predict creep strain development for a lead time of 50 years on the basis of the data obtained in experiments shorter than 608 days, as specified in Standard EN 13163. Sufficiently accurate point-wise prediction of creep strain of EPS slabs under a compressive stress sigma(c) of (0.25 and 0.35)(sigma 10%) for a lead time of 50 years is possible by extrapolating the creep described via a power equation (Findley W.N.) and using data from the 65-day direct experiment.
