将石灰石粉作为掺合料加入混凝土中,研究石灰石粉对其工作性与力学性能的影响,试验表明;石灰石粉以适当的掺量在混凝土中应用,可以改善混凝土的和易性、工作性、降低混凝土坍落度损失、力学性能提高、增大坍落度而不泌水,应用于高强度混凝土时,可以降低混凝土的粘聚性提高混凝土的流动性。 Limestone powder was added into concrete as an admixture to study the effect of limestone powder on its workability and mechanical properties. Tests have shown that the application of limestone powder with appropriate amount of concrete can improve the workability and workability of concrete. Reduce the loss of concrete slump, improve mechanical properties, increase the slump without bleeding, when applied to high-strength concrete, can reduce the cohesion of concrete to improve the fluidity of the concrete.
