摘要
水泥细度是影响混凝土质量的重要因素之一,控制水泥细度是保证混凝土质量的关键步骤。研究了水泥细度对不同强度等级混凝土抗压强度、早期干燥收缩和自身收缩、早期开裂等性能的影响。结果表明:随着水泥细度的增加,早期水化程度加大,混凝土早期强度越高,早期收缩及开裂越明显。
Cement fineness is one of the important factors which influence the concrete quality, so to control the cement fineness is key step for ensuring the concrete performance.Research the influence of cement fineness on compressive strength, early age dryness shrinkage and self-shrinkage, forepart crack of different strength grade concrete.The result show that with the increase of the cement fineness, the forepart hydration rate and early age strength increase, and also, the shrinkage and crack of concrete may be more evidence.
