Problems solved by technology

However, this technology requires multiple hydration reactions, which is not conducive to on-site deployment and construction
However, the early strength and fluidity of this material are insufficient, and admixtures such as calcium lignosulfonate are needed to adjust the fluidity and plastic deformation properties, so it is not suitable for use as structural anchoring materials

Abstract

The invention discloses a high-strength quick-setting polymer mortar. The polymer mortar comprises, by weight, 8-15 parts of aggregate, a composite excitation component and a gelling component, wherein the composite excitation component comprises, by weight, 2-4 parts of a sodium silicate dilute solution and 0.5-1 part of an alkaline solution; and the gelling component comprises, by weight, 1-2 parts of fly ash and 4-8 parts of mineral powder. The composite excitation component excites the gelling component to generate weight reduction reaction, so that excellent early strength is realized; and a C-A-S-H gel microstructure generated through a reaction can be tightly bonded to the surfaces of composite materials such as grids, rib materials and plates, so the bonding performance of the composite materials and a reinforced structure is guaranteed.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a polymer mortar for fly ash with high strength and high cohesion, which is suitable for composite material reinforcement construction. Background technique [0002] In the reinforcement and reconstruction projects of composite materials such as grids, bars, plates, etc., it is necessary to integrate the composite materials with the reinforcement structure through appropriate anchoring measures. The key to the anchoring measures is to make full use of the mechanical characteristics of the composite material and at the same time ensure that the anchoring material can deform in concert with the composite material and the reinforced structure. Commonly used anchoring measures generally include mechanical anchoring and bonding anchoring. However, under the repeated action of external loads, the reinforcement structure inevitably leads to the deterioration of mechanical anchoring de...
