Embodiment Construction

[0014] Such as figure 1 , figure 2 As shown, the grid baffle is connected with the lifting system to provide power for the whole extrusion process. In order to ensure the formation of a closed system between the double-layer stirring pot and the grid baffle, a rubber sleeve is set at the ring of the grid baffle. The double-layer stirring pot is composed of inner and outer layers, which can rotate with each other, and extrusion outlets are respectively set at the bottom. During the stirring process, the inner and outer extrusion outlets are misaligned with each other to ensure the sealing of the mixing pot, and the inner and outer extrusion outlets overlap each other during the extrusion process to realize the smooth extrusion of the geopolymer.

[0015] Such as image 3 As shown, when a large volume of paving is required, the flat nozzle can be used to lay geopolymer materials faster and more smoothly, and it is mostly used for paving roads or runways.

Abstract

The invention discloses an extrusion method for on-site construction of geopolymer, wherein a lattice baffle plate is connected with a lifting system to provide power for the whole extrusion process.In order to ensure that a closed system is formed between the double-layer stirring pot and the lattice baffle, a rubber sleeve is arranged at the circular ring of the lattice baffle. The double-layerstirring pot is composed of inner and outer layers, which can rotate mutually, and the extrusion outlets are arranged at the bottom of the double-layer stirring pot respectively. In the mixing process, the internal and external extrusion outlets are dislocated to ensure the sealing of the mixing pot, and the internal and external extrusion outlets overlap each other to achieve the smooth extrusion of geopolymer. The invention solves the field layout problem caused by the geopolymer with high viscosity and poor fluidity, and has relatively important significance for the practical application of the geopolymer.

Description

technical field [0001] The invention relates to an extrusion method for on-site construction of metakaolin-based geopolymers. Specifically, it cooperates with the on-site mixing device of geopolymers, extrudes the geopolymers by mechanical extrusion, and realizes the laying or filling technology of geopolymers in different construction sites through two different nozzles. Background technique [0002] Metakaolin-based geopolymer (Geopolymer) is a new type of industrial building material obtained by proper processing of metakaolin and alkaline activator. Under the catalysis of GGBS (blast furnace slag powder), the initial setting time and final setting time of metakaolin-based geopolymers can be greatly reduced, and its strength can be increased. Experimental research shows that when metakaolin is replaced by GGBS and other qualities, its final setting time can be controlled within 30 minutes, and its strength can be increased by about 150%. Therefore, the application prosp...
