摘要
在不影响混凝土工作性和力学性能的前提下,掺加聚丙烯纤维或高需水性树脂,使得混凝土的抗裂性得到改善。某超高层建筑的钢筋桁架混凝土组合楼板的实际应用效果表明,上述措施大幅提高了C40混凝土楼板的抗裂性能。
The anti-cracking ability of concrete was improved by dosage of super absorbent polymer (SAP) or polypropylene (PP) fiber on the precondition of keeping same workability and mechanical properties of concrete. The actual construction result in the steel bar truss and concrete composite floor of a tall building in Beijing shows that these measurements obviously improves the anti-cracking ability of C40 concrete floor.
