摘要
通过不同水灰比对高石粉含量(10%)机制砂砂浆性能的影响,探讨了水灰比对高石粉含量机制砂砂浆开裂、收缩、质量损失及强度的影响规律。结果表明:随水灰比增大,高石粉含量机制砂砂浆开裂敏感性降低,收缩减小,质量损失增大,强度减小,折压比与砂浆开裂敏感性无关联。
Through the influence of the different water cement ratio on the manufactured-sand mortar performance of high stone powder content （10%）, the rule was discussed that mortar cracking, shrinkage, mass loss and strength were influenced by water cement ratio. The results indicate that cracking-sensitivity decreasing, shrinkage-reducing, quality loss-increasing and strength reduction are researched along with the increasing of water cement ratio, the ratio of compressive strength to Flexural strength and the cracking sensitivity of mortar is no association.
