Salt-spray-corrosion-resistant mortar for high-speed railway bridge support and preparation method of salt-spray-corrosion-resistant mortar
The invention relates to a salt-spray-corrosion-resistant mortar for a high-speed railway bridge support and a preparation method of the salt-spray-corrosion-resistant mortar for the high-speed railway bridge support. The concrete raw materials comprise the following components in percentage by weight: 20%-40% of ordinary cement, 5%-30% of rapid hardening cement, 0.5%-3.0% of silica fume, 0.5%-4.0% of an early strength agent, 0.01%-0.1% of a thickening time control agent, 0.5%-1.5% of a water reducing agent, 0.001%-0.05% of an air entraining agent, 1.0%-5.0% of an expanding agent, 2.0%-5.0% of a compacting agent, 0.01%-0.5% of a waterproof agent and 35%-50% of fine aggregate. The salt-spray-corrosion-resistant mortar for the high-speed railway bridge support has the advantages of being good in mortar pouring stability, rapid in early strength development, high in compactness, high in impermeability, high in corrosion resistance coefficient and the like under the action of salt-spray environments such as chlorine salt and sulfate.
本发明涉及一种高速铁路桥梁支座用耐盐雾腐蚀砂浆及其制备方法，本发明的高速铁路桥梁支座用耐盐雾腐蚀砂浆按照重量百分比计，具体原料包括以下组分：普通水泥20%～40%、快硬水泥5%～30%、硅灰0.5%～3.0%、早强剂0.5%～4.0%、调凝剂0.01%～0.1%、减水剂0.5%～1.5%、引气剂0.001%～0.05%、膨胀剂1.0%～5.0%、密实剂2.0%～5.0%、防水剂0.01%～0.5%、细集料35%～50%。本发明所得高速铁路桥梁支座用耐盐雾腐蚀砂浆具有：砂浆灌注稳定性好，早期强度发展快，在氯盐、硫酸盐等盐雾环境作用下，密实度高，抗渗性强，抗蚀系数高等特点。
