摘要：

In this work, the long-term shrinkage of concrete containing some Icelandic porous aggregates is examined. This was done by measuring the length change of concrete prisms in accordance with the ASTM C157/C157M-99 standard. The results indicate that concrete continues to shrink over long period of time, independent to evaporation caused by drying. The results also show that the measured shrinkage is considerably higher than estimated shrinkage according to the Eurocode 2 (EC2) prediction model. Due to this difference, deflection can be underestimated when designing concrete structures, as shrinkage influences deflection according to EC2.
