Limestone powder concrete surface strengthening agent as well as preparation method and application thereof
The invention provides a limestone powder concrete surface strengthening agent as well as a preparation method and application thereof. The limestone powder concrete surface strengthening agent comprises a component A and a component B. The component A consists of, in percentage by mass, 10-20% of a permeation and expansion component, 15-25% of calcium nitrate, 1-3% of a permeation-aiding component, 10-15% of a crystallization-aiding component and the balance water; and the component B consists of 10-20% of a permeation hardening component, 1-2% of a waterproof component and the balance of water. The concrete surface strengthening agent disclosed by the invention has the effects of improving the concrete rebound strength of concrete, reducing the carbonization depth and weakening the carbonization speed, and is simple in preparation and use method, low in cost and wide in adaptability.
本发明提供了一种石灰石粉混凝土表面提强剂及其制备方法与应用。该石灰石粉混凝土表面提强剂包括A组分和B组分，以质量百分数计，A组分由10％‑20％渗透膨胀组分、15‑25％硝酸钙、1‑3％助渗组分、10‑15％助结晶组分和余量的水组成；B组分由10‑20％渗透硬化组分、1‑2％防水组分和余量的水组成。本发明的混凝土表面提强剂具有提高混凝土的混凝土回弹强度、降低碳化深度、减弱碳化速度的效果，且制备和使用方法简单、成本低、适应性广。
