高性能混凝土可以通过调整配比、添加矿渣外掺剂等方法提高性能.为研究矿渣含量对高性能混凝土力学性能的影响,本文通过制备矿渣含量为20％、25％、30％、35％、40％的矿渣混凝土和普通混凝土,分别在养护龄期为7、28、60、90天时进行立方体抗压强度试验,分析矿渣含量对高性能混凝土力学性能的影响.结果表明:在混凝土水化早期,随着矿渣含量越高,混凝土强度越小,同时矿渣有延迟混凝土水化强度提升的作用,使得矿渣混凝土强度增长速率随养护龄期的增长而逐渐减小.0.38水灰比下,矿渣含量为30％时,养护28天混凝土强度

Photocatalytic oxidative organic reactions are important synthetic transformations,and research on reac-tion selectivity by reactive oxygen species (ROS) is significant.To date,however,there has rarely been any focus on the directed generation of ROSs.Her
Wigner-Yanase skew information could quantify the quantum uncertainty of the observables that are not commuting with a conserved quantity.We present the uncertainty principle for two successive projective measurements in terms of Wigner-Yanase skew inform
Plants also have to follow their diet to be healthy.In addition to light,water,and CO2,they need mineral nutrients which have to be actively uptaken from the soil where their availability is often lim-ited [1].However,under natural conditions,plants are n
