Embodiment Construction

[0018] Put the prepared metakaolin (or metakaolin and GGBS solid mixture) into the stirring pot and stir for two minutes. Then slowly pour the configured low modulus (general modulus 1.3) water glass into the stirring pot according to the required ratio and stir, and stir for 10 minutes to obtain the metakaolin-based geopolymer colloid. Then the lifting system is started, and the stirring blade is separated from the grid baffle through the transmission of the gear, the stirring blade moves upward, and the grid baffle moves downward. When the mixing blade is completely separated from the blocking groove, the blocking groove is automatically closed by the built-in spring system. Finally, the grid baffle continues to descend to form a closed system with the stirring pot, and the geopolymer is extruded through the pressure formed by the grid baffle. After the extrusion is completed, the lifting system can continue to be started, so that the grid baffle and the stirring blade are ...

Abstract

The invention discloses a device for field stirring of a geopolymer; prepared metakaolin or a metakaolin and GGBS solid mixture is put into a stirring pot and stirred for two minutes. Prepared water glass with low modulus of 1.3 is slowly poured into the stirring pot and stirred in a required proportion, and after stirring is performed for 10 min, a metakaolin-based geopolymer colloid is obtained.Then a lifting system is started, and stirring blades are separated from a grid baffle plate by the transmission of gears, the stirring blades move upwards and the grid baffle plate moves downwards.When the stirring blades are completely separated from a grid groove, the grid baffle groove is automatically closed by a built-in spring system. Finally, the grid baffle plate continues to drop and forms a closed system with the stirring pot, and the geopolymer is extruded through the pressure formed by the grid baffle plate. After extrusion is completed, the lifting system can continue to start,so that the grid baffle plate and the stirring blades are connected through clamp grooves. The device is of great significance to the practical application of the geopolymer.

Description

technical field [0001] The invention is a device for on-site stirring of metakaolin-based geopolymers. Specifically, it is a device that solves the on-site mixing and use of geopolymers under engineering backgrounds such as repairing cracks or filling damaged roadbeds. Background technique [0002] Metakaolin-based geopolymer (Geopolymer) is a new type of industrial building material obtained by proper processing of metakaolin and alkaline activator. It has the characteristics of fast setting and early strength, its 24h compressive strength can reach more than 30MPa, and its 28d compressive strength can reach more than 50MPa, so it is widely used in repairing cracks or filling damaged roadbeds and other projects. Due to its rapid setting characteristics, metakaolin-based geopolymers can only be prepared by in-situ stirring. [0003] Metakaolin-based geopolymers are more viscous than ready-made concrete, so drum mixers cannot be used for mixing, but blade mixers should be u...
