Negative-temperature porous grouting material and preparation method thereof
The invention discloses a negative-temperature duct grouting material and a preparation method thereof, and belongs to the technical field of building materials. The anti-freezing and anti-freezing concrete is prepared from the following components in parts by weight: 350 to 500 parts of a cementing material, 500 to 650 parts of a heat source material, 3 to 7 parts of a water reducing component, 0.5 to 3 parts of an expansion component, 100 to 140 parts of an anti-freezing component, 1 to 3 parts of a retarding component, 10 to 20 parts of a rust inhibiting component and 0.2 to 0.8 part of a stabilizing component, the preparation method of the heat source material comprises the following steps: firstly, removing chloride ions in salty mud; then preserving heat for 2-6 hours at 350-500 DEG C, raising the temperature to 850-900 DEG C, preserving heat for 2-6 hours, continuously raising the temperature to 1100-1300 DEG C, preserving heat for 3-6 hours, and cooling to obtain a calcined product; adding sodium tripolyphosphate and melamine into the calcined product, grinding, and sieving to obtain powder; and mixing the powder with sulphoaluminate cement to obtain the cement. Under the combined action of all the components, the grouting material disclosed by the invention can maintain very high fluidity in a negative temperature environment and also has excellent mechanical properties, and both the early strength and the later strength can meet the requirements of practical application.
本发明公开一种负温孔道压浆材料及其制备方法，属于建筑材料技术领域。所述包括以下重量份数的各组分：胶凝材料350～500份、热源材料500～650份、减水组分3～7份、膨胀组分0.5～3份、防冻组分100～140份、缓凝组分1～3份、阻锈组分10～20份、稳定组分0.2～0.8份；所述热源材料的制备方法如下：先去除盐泥中的氯离子；然后在350～500℃下保温2～6h，升温至850～900℃后保温2～6h继续升温至1100～1300℃后保温3～6h，冷却后得到煅烧产物；在煅烧产物中加入三聚磷酸钠和三聚氰胺后进行粉磨，过筛后得到粉体；将粉体与硫铝酸盐水泥进行混合，即得。在各组分的共同作用下，本发明的压浆材料在负温环境下也能保持很高的流动性，同时还具有优异的力学性能，早期强度和后期强度均可满足实际应用的需求。
