Waterproof pavement premix for bridge floor
The invention relates to a bridge deck waterproof paving premix which comprises a component A and a component B. The component A comprises the following raw materials in parts: 270-420 parts of cement, 280-600 parts of quartz sand, 150-250 parts of ground mineral powder, 60-80 parts of silica fume, 1-5 parts of a nano anti-permeability agent, 1-3 parts of a water reducing agent and 1-3 parts of an internal curing agent, and the component B comprises 40-160 parts of copper-plated steel fibers. The premix for waterproof pavement of the bridge deck is a material designed according to a compact stacking theory, and has ultrahigh strength, high toughness, low permeability and high volume stability, so that the problems that common waterproof concrete, additive-added waterproof concrete and expansive waterproof concrete in waterproof concrete pavement of the bridge deck are high in shrinkage rate and easy to crack are solved; and the service lives of common waterproof concrete, waterproof concrete added with additives and expansive waterproof concrete are greatly prolonged.
本发明涉及一种桥面防水铺装预混料，包括A组分和B组分，所述A组分包括以下份数的原料：水泥270份‑420份、石英砂280份‑600份、磨细矿粉150份‑250份、硅灰60份‑80份，纳米抗渗剂1份‑5份、减水剂1份‑3份和内养护剂1份‑3份，所述B组分包括镀铜钢纤维40份‑160份。该桥面防水铺装预混料，根据紧密堆枳理论设计出来的材料，具有“超高强度”、“高韧性”、“低渗透性”和“高体积稳定性”，以解决桥面防水混凝土铺装中普通防水混凝土、添加外加剂防水混凝土、膨胀型防水混凝土收缩率大，易开裂问题，并且大幅度的提高了普通防水混凝土、添加外加剂防水混凝土和膨胀型防水混凝土的使用寿命。
