4、和粉煤灰的100MPa高强度自流平混凝土试验研究 减少人口稠密区混凝土施工所产生的噪音，混凝土构件的加固，如梁的加高、墙的加厚和柱子的加粗等，采用自流平混凝土应该是解决上述问题的有效途径，本文主要研究高强混凝土的自流平问题。 本文研究所采用的基本原材料是：52.5PI硅酸盐水泥、中砂或粗砂、5-25mm致密的岩浆岩碎石；掺合料为硅粉和I级粉煤灰；外加剂为NF-2-6缓凝高效减水剂（水剂）。 本文所要讨论的问题是：内掺硅粉和粉煤灰对混凝土混合料流动性和硬化混凝土抗压强度的影响；混凝土28d抗压强度规律；混凝土的后期强度等。一、内掺硅粉和粉煤灰对混凝土抗压强度和流动性的影响 试验采用正交设计的方法
