摘要
本文对用细度模数为０．５６的特细砂配制２８天抗压强度达８０ＭＰａ，抗渗透压大于４．０ＭＰａ，收缩徐变小的高强混凝土进行了孔隙结构、水化产物。
A high strength concrete with 28 day strength up to 80 MPa from superfine sand with fineness modulus of 0.56 is obtained.It has a permeability resistance of 4.0 MPa and small shrinkage creep.Experiment and study were carried out on its pore structure,hydration products and microhardness of transient area in cement paste and aggregate interface. The essence for high strength of such concrete was revealed.
