Function gradient concrete based on alkali-activated slag and Portland cement
The invention discloses functional gradient concrete based on alkali-activated slag and Portland cement. The functional gradient concrete is formed by covering the surface of alkali-activated slag concrete with a Portland cement mortar layer or a Portland cement concrete layer, or covering the surface of the Portland cement concrete with an alkali-activated slag mortar layer or an alkali-activated slag concrete layer, so that the carbonization resistance of the alkali-activated slag concrete or the chloride ion penetration resistance of the Portland cement concrete is improved. The functional gradient concrete disclosed by the invention has good comprehensive performance, such as excellent carbonization resistance and chloride ion penetration resistance, and is particularly suitable for being used in places with serious chloride ion erosion or places with both chloride ion erosion and carbonization.
本发明公开了基于碱激发矿渣和硅酸盐水泥的功能梯度混凝土，是在碱激发矿渣混凝土的表面覆盖有一层硅酸盐水泥砂浆层或硅酸盐水泥混凝土层，或者是在硅酸盐水泥混凝土的表面覆盖有一层碱激发矿渣砂浆层或碱激发矿渣混凝土层，以提高碱激发矿渣混凝土的抗碳化性能或者硅酸盐水泥混凝土的抗氯离子渗透性能。本发明的功能梯度混凝土具有良好的综合性能，如优良的抗碳化性能、抗氯离子渗透性能等，特别适合氯离子侵蚀严重或既有氯离子侵蚀又有碳化作用的地方使用。
