AI Technical Summary

Technical Problem

Traditional cement concrete materials have limited functionality and poor toughness, making them prone to plastic deformation and shrinkage, which can lead to defects such as cracking and outer layer peeling, thus affecting the lifespan of the project.

Method used

By adding MgAl-LDH@CNTs composites, halloysite nanotubes, and acid-modified silicon nitride fibers to cement, combined with water-reducing agents and dispersants, the dispersion and hydration of the materials are promoted, thereby improving the pore properties and mechanical properties of the cement.

Benefits of technology

It significantly improves the compressive and flexural strength of cement, enhances the overall performance of the material, and makes it perform excellently in building exterior wall applications.

Abstract

本发明属于水泥技术领域,具体涉及一种环保绿色水泥及其制备方法和应用。本发明提供的水泥,按重量份计,所述水泥包括以下组分:水泥 180~240份;硅灰 120~160份;石英砂 40~80份;MgAl‑LDH@CNTs复合材料 6~12份;埃洛石纳米管 15~25份;酸改性的氮化硅纳米纤维 4~8份;减水剂 8~12份;分散剂4~8份;水160~200份。本发明通过原位在CNTs表面负载MgAl‑LDH,即保留了CNTs之间过度缠绕而造成团聚,而且促进MgAl‑LDH和CNTs在水泥中的分散,进而促进了水泥力学性能的改善,同时配合埃洛石纳米管和酸改性的氮化硅纳米纤维,有效改善了水泥的综合性能,使其在建筑外墙应用中得到广泛应用。
