在今年的美国混凝土协会年会上,法国A.CRIAUD、C.VERNET和C.DEFOSSE介绍,他们用我院研制的快速法测试了八种加拿大混凝土集料以及美国、意大利、丹麦和南非等国的集料,并与ASTMC227、NBRI和ACNOR等方法测试的结果进行比较,表明此方法能从混凝土碱—硅酸反应和碱—硅酸盐反应角度可靠地鉴定集料的性能,并且能鉴定出美国ASTMC227所不能鉴定的集料。
At this year’s American Concrete Association Annual Conference, French A.CRIAUD, C.VERNET and C.DEFOSSE introduced that they used the rapid method developed by our institute to test eight Canadian concrete aggregates and the United States, Italy, Denmark and South Africa and other countries. The aggregates were compared with the results of the ASTM C227, NBRI, and ACNOR tests, indicating that this method can reliably identify aggregate performance from the perspective of concrete alkali-silica reaction and alkali-silicate reaction, and can identify Aggregates not identifiable by ASTM C227 in the United States.
