适用范围：This European Standard specifies a method of assessing the frost resistance of an aggregate when itis subjected to the cyclic action of freezing and thawing in the presence of 1% solution of NaCI inde-ionized or distilled water.The results of this test provide a means for assessing an aggregate's resistance to this form ofweathering in areas where frequent freeze-thaw cycling occurs with seawater sprays or abundant de-icers conditions, and where result values of EN 1367-1 test method do not describe correctlyaggregate performance in extreme conditions.This European Standard gives the option to control the thawing sequence either by immersion in wateror by using air circulation in the low temperature cabinet to obtain the required reference temperature.This test method is applicable to coarse aggregates or to coarse aggregates' fractions of all-inmaterials. This method is not appropriate for lightweight, aggregates covered by EN 13055 oraggregates which can not be submitted to 110 ℃ oven drying.
