颗粒级配对混凝土强度的影响——以5～25mm连续粒级卵石为例

Effect of Particle Size on Concrete Strength——Taking 5～25 mm Continuous Granular Pebbles as an Example

混凝土强度是混凝土施工中控制工程质量和工程验收时的重要依据。卵石对混凝土的强度影响比较大,文章以5~25 mm连续粒级卵石为研究对象,研究颗粒级配对混凝土强度的影响,试验结果表明:级配良好的卵石不但使混凝土有良好的工作性,还使混凝土具有较高的强度,粒径过大或者过小,均无法获得较高的强度。为施工企业控制混凝土的施工质量提供了参考。

Concrete strength is an important basis for quality control and acceptance of concrete during construction.The effect of pebbles on the strength of concrete is relatively large.Taking 5-25 mm continuous granular pebbles as the object of study, this thesis investigated the influence of particle size on concrete strength, tested results showed that good gradation gravel not only makes the concrete has good workability, but also make the concrete with high strength, size too big or too small, are unable to obtain high strength.It provided reference for construction enterprises to control the quality of concrete construction.
