Embodiment 1

[0030] 30 g of human hair was weighed and dissolved in 1000 g of 15% by weight sodium hydroxide solution to obtain a non-polar surfactant solution.

[0031] Weigh 1000g of fly ash, 520g of slag, 190g of steel slag, 65g of high-calcium fly ash, and 177g of alkaline activator, place them in a dry powder mixer, and stir and mix for 5 minutes at a speed of 57 rpm to obtain a uniform dry powder mix. The material is reserved, and when used in actual construction, the dry powder mixture is placed in a mixer, 190 g of the above-mentioned surfactant solution is added, and 390 g of pure water (pH=7) is added, and grouting is performed while mixing and stirring.

[0032] After the above materials are condensed, they are boiled in boiling water for 8 hours, without deformation, and the stability is qualified.

[0033] Take a 2cm × 2cm × 2cm test piece, and its weight is 25% higher than that without surfactant.

Embodiment 2

[0035] Weigh 250 g of chicken feathers and dissolve in 1000 g of 2.5% by weight sodium hydroxide solution to obtain a non-polar surfactant solution.

[0036] Weigh 1225g of fly ash, 400g of slag, 195g of steel slag, 55g of high-calcium fly ash, and 77g of alkaline activator, place them in a dry powder mixer, and stir and mix for 5 minutes at a speed of 57 rpm to obtain a uniform dry powder mix. The material is reserved, and when used in actual construction, the dry powder mixture is placed in a mixer, 60 g of the above-mentioned surfactant solution is added, and 420 g of industrial water (pH=7) is added, and grouting is performed while mixing and stirring.

Embodiment 3

[0038] 20 g of human hair was weighed and dissolved in 100 g of 10% by weight sodium hydroxide solution to obtain a non-polar surfactant solution.

[0039] Weigh 568g of fly ash, 878g of slag, 195g of steel slag, 146g of high-calcium fly ash, and 165g of alkaline activator and place them in a dry powder mixer, stir and mix for 5 minutes at a speed of 57 rpm to obtain a uniform dry powder mix The material is reserved, and when used in actual construction, the dry powder mixture is placed in a mixer, 80 g of the above-mentioned surfactant solution is added, and 585 g of industrial water (pH=7.5) is added, while mixing and stirring, while grouting.

Abstract

The invention relates to a soil consolidation grouting material of geopolymer, which is composed of fly ash, slag, steel slag, high-calcium fly ash, alkali-activator, nonpolar alkaline surface active agent and water, wherein the nonpolar alkaline surface active agent is obtained by reacting curled hair of human or animal with sodium hydroxide, and the pH value of the water is larger than 6.5. The soil consolidation grouting material of geopolymer of the invention is high in initial strength, fine in water stability, liquidity, frost-resisting property and service durability and the like, simultaneously, the soil consolidation grouting material of geopolymer has the characteristic of low manufacturing cost and reducing environmental pollution.

Description

technical field [0001] The invention relates to a grouting material, in particular to a geopolymer soil consolidation grouting material used for road soil embankment grouting reinforcement. Background technique [0002] With the rapid development of municipal and highway construction in recent years, the traffic flow and axle load have increased rapidly. After a period of use, municipal roads and highways will have various structural defects such as subsidence, muddying, and cracks. The existing maintenance technology is mainly to reprocess the road surface or to dig and rebuild the road structure, which requires a long period of traffic closure; the surface treatment cannot cure the disease, and the cost of digging and rebuilding is high, and the environment pollutes and affects the society. Therefore, adopting non-excavation maintenance technology that can quickly open up traffic is a social need. One of the important contents of adopting grouting non-excavation technolog...
