摘要
本文通过理论和试验分析了骨料特性对碾压混凝土抗裂性的影响 ,提出了适于评价碾压混凝土抗裂性指标———抗裂参数Φ ,并用抗裂参数Φ判断用不同弹性模量、强度的骨料拌制的碾压混凝土的抗裂性大小 ,对提高碾压混凝土的抗裂能力具有指导意义。
The aggregate characteristics affecting anti\|cracking capability of roller compacted concrete are studied in theory and by experiment. An anti\|cracking parameter Φ is introduced to indicate the anti\|cracking capability of roller compacted concrete. The parameter Φ can then be used as a guide\|line to evaluate the anti\|cracking capability of roller compacted concrete mixed with aggregates of different modulus of elasticity and strength.
