Anti-crack composite additive and oil-seepage-proof concrete with same
The invention belongs to the field of building material engineering, in particular to an anti-cracking composite additive. According to the anti-cracking composite additive, through compounding of theplastic expansion component, the delayed hydration type CaO expansion component, the light burning nanometer MgO expansion component and the polymer water-absorbing resin, concrete shrinkage can be compensated in stages in application, and the polymer water-absorbing resin in the anti-cracking composite additive also has a synergistic effect. The invention further discloses oil-seepage-proof concrete based on the anti-crack composite concrete, the superfine coal ash and the superfine mineral powder can fill tiny gaps of the concrete, and the optimal close packing effect of a gelling system isformed; the organic silicon resin can be used for filling gel holes of the concrete and plays a role in blocking oily molecules due to the oleophobic effect so that the porosity, the compactness andthe oleophobicity of the oil-seepage-proof concrete are further reduced.
本发明属于建筑材料工程领域，尤其涉及一种抗裂复合添加剂，该抗裂复合添加剂通过复配塑性膨胀组分、延缓水化型CaO膨胀组分、轻烧纳米MgO膨胀组分和高分子吸水树脂，可实现在应用时分阶段地对混凝土收缩进行补偿，且其中的高分子吸水树脂还起到协同作用。本发明还公开了一种基于上述抗裂复合混凝土的防油渗混凝土，其中的超细粉煤灰和超细矿粉能够填充混凝土的微小空隙，形成胶凝体系最佳紧密堆积效果；而有机硅树脂能够填充混凝土凝胶孔并因憎油作用而起到阻隔油性分子的作用，进一步降低了防油渗混凝土的孔隙率、密实性和憎油性。
