Experimental Research on Application of High-performance Concrete Grouting Materials in Disease Control of the Roadbed |
| |
| Abstract: | The effects of materials such as expansion agent, fly ash, silica fume and water reducer on the fluidity and mechanical properties of grouting materials were studied in detail. The general flow of grouting construction was summarized from the perspective of grout quality assurance. According to the research, the grouting construction should be closely combined with the disease characteristics and the construction conditions of the conservation area. It can allocate and design high-performance grouting materials with pertinence and applicability from the perspective of grouting raw materials. |
