High-ground-temperature tunnel sprayed concrete modified material and preparation method thereof
The invention relates to the technical field of tunnel and underground engineering construction, and provides a high-ground-temperature tunnel sprayed concrete modified material and a preparation method thereof. The heat-insulation and heat-insulation soap paste comprises the following raw materials in percentage by mass: 5-15% of an alcohol amine organic early-strength compound, 10-20% of an enhanced polyester plastic stabilizer, 15-25% of a C7 polyether compound plasticizing and water-reducing colloid, 1-3% of an ultra-micro nano stable soap paste air entraining agent, 10-20% of boron titanium vanadium ore micron-sized heat-insulation powder or extract and the balance of deionized distilled water, wherein the total percentage is 100%. The high-ground-temperature tunnel sprayed concrete modified material provided by the invention can improve the workability, heat transfer performance and mechanical property of concrete in a high-ground-temperature tunnel environment, and improve the safety and reliability of high-ground-temperature tunnel construction.
