石灰石粉掺量对混凝土性能影响的试验研究

水泥混凝土是目前土木工程建设中最为广泛的材料,它是以水泥为黏结剂,集料为填充物的混合材料,而其中砂石集料的作用往往被忽视,石灰石粉作为砂石集料中的细颗粒成分,作为混凝土的填充使用,不仅使混凝土的级配更合理,而且会影响混凝土的物理力学性能和耐久性。通过研究了石灰石粉作为混凝土掺合料对混凝土工作性能、力学性能、耐久性等的影响和改善,使石灰石粉的作用得到认可,为混凝土材料的发展提供依据,具有很好的经济效益和社会效益。

Experimental study on the effect of powder dosage to concrete performance

Concrete is the most widely used materials in civil engineering,it is a mixture material with cement as its binder,aggregate as its filler,however,the role of sand and gravel aggregates are often ignored.As fine particle composition of sand and gravel compound,limestone powder is used in concrete as filling material,not only with a more reasonable level of concrete,and will affect the physical and mechanical properties and durability of concrete.By studying the effect of work properties,mechanical properties,durability to concrete,so the role of limestone powder can be recognized,and provide the basis for the concrete materials development,and with good economic and social benefits.
