High-strength and corrosion-resistant additive, concrete, preparation method and application
The invention discloses a high-strength and corrosion-resistant additive, concrete, a preparation method and application, and belongs to the technical field of concrete preparation. The concrete comprises an additive, cement, sand, stones and a water reducing agent. The additive comprises 30wt%-40wt% of desulfurization tower bottom ash, 35wt%-45wt% of silicon powder and 15wt%-30wt% of anhydrite. The high-strength and corrosion-resistant concrete prepared from the desulfurization tower bottom ash has the following advantage that the high-strength and corrosion-resistant concrete is suitable for concrete members with the strength of 60-100 MPa. Under the condition of the same water-binder ratio, the compressive strength of the concrete is improved by 15%-20%.
本发明公开了一种高强、耐腐蚀添加剂及混凝土、制备方法和应用，属于混凝土制备的技术领域。包括添加剂、水泥、砂、石子和减水剂。其中所述添加剂包括：30wt%~40wt%的脱硫塔底灰、35wt%~45wt%的硅粉和15wt%~30wt%的硬石膏。本发明利用脱硫塔底灰配制高强耐腐蚀混凝土具有以下优点：适用于60MPa~100MPa强度等级的混凝土构件。在相同水胶比条件下，混凝土抗压强度提高15%~20%。
