Abstract

The invention provides a grouting agent and a preparation method thereof, and relates to a concrete additive and a preparation method thereof. The grouting agent prepared according to the method is applicable to the fields of grouting of equipment foundation, and anchoring grouting of ground anchor systems. The grouting agent comprises 7-12 parts of silica fume, 2-4 parts of fly ash, 3-5 parts ofpolycarboxylic acid, 1-1.5 parts of magnesium oxide, 0-0.05 part of sodium thiosulfate, 0.3 part of sodium sulfate, 0.1-0.2 part of beta-naphthalene sulfonated formaldehyde condensates, 0.01 part of organic silicon, 0.1 part of rosin saponated substance, 0.2-0.3 part of sodium carbonate, and 550-650 parts of cement. According to the grouting gent prepared according to the method, the dose of the added components can be adjusted and controlled based on different types of the used cement and different use temperatures, so that the grouting agent prepared according to the method can work normallyin various environments and is not influenced by different types of cement.

Description

[0001] technology neighborhood

[0002] The invention relates to a concrete admixture and a preparation method thereof. The grouting agent obtained by the method can be used in the fields of equipment foundation grouting, ground anchor system anchoring grouting and the like. Background technique

[0003] The grouting agent is mainly prepared by mixing various materials such as high-efficiency water reducer, expansion agent, early strength agent, retarder, defoamer, plasticizer, etc. However, the grouting agent prepared by the present invention does not add the main volume-stabilizing component cement in the process of preparation. This is mainly because the usual grouting agent has certain limitations in the process of use and is easily affected by the type of cement and environmental factors. The impact on the use of grouting agent caused performance defects.
