摘要
应用灰色关联度法分别计算了半刚性基层材料最大干缩应变与目前常用的干缩抗裂性评价指标间的关联度以及最大温缩应变与目前常用的温缩抗裂性评价指标间的关联度.结果表明,采用干缩能抗裂系数和温缩能抗裂系数能更好地反映半刚性基层材料的收缩开裂特性,该组指标评价半刚性基层材料抗裂性更为合理.
The theory of grey relational grade was applied to calculate the relational grades between the maximum dry shrinkage strain and some evaluation indices of cracking resistance to dry shrinkage,and the relational grades between the maximum thermal shrinkage strain and some evaluation indices of cracking resistance to thermal shrinkage. The result indicates that it is more reasonable to adopt dry shrinkage energy anti-cracking coefficient and thermal shrinkage energy anti-cracking coefficient to evaluate the cracking resistance of semi-rigid base layer materials.
