Abstract

The invention discloses a pre-alkaline inorganic mineral polymer-based fast repair mortar and a preparation method thereof, which belong to the field of building materials. The pre-alkaline inorganic mineral polymer-based rapid repair mortar includes raw material components and parts by mass respectively: 28-55 parts of pre-alkali solution, 80-100 parts of slag, and 1-8 parts of coagulant to increase flow Use 10-25 parts of fly ash, 110-130 parts of sand, and 15-22 parts of water. The materials included in the pre-alkali solution and their mass parts are: 13-36 parts of silicon-aluminum material, 15-20 parts of alkali excitation solution. The preparation method is as follows: first prepare the alkali excitation liquid, then mix it with the silicon-aluminum material heated by microwave for pre-alkalinization reaction to obtain the pre-alkaline liquid, then add other raw materials and stir to prepare it. The pre-alkalised inorganic mineral polymer-based rapid repair mortar can adjust the setting time according to the repair demand, and can also improve the strength of the pre-alkaliized inorganic mineral polymer-based rapid repair mortar, and is widely used in the rapid repair of roads.

Description

technical field [0001] The invention relates to the technical field of building materials, and is a quick-repair mortar, in particular to a pre-alkalised inorganic mineral polymer-based quick-repair mortar and a preparation method thereof. Background technique [0002] There are mainly two kinds of existing repair mortars, one is cement-based repair mortar; the other is high-molecular polymer-based repair mortar. Cement-based repair mortar: Ordinary Portland cement has a slow reaction rate at the initial stage of hydration, and has poor bonding performance with the old road surface. After pouring, it needs maintenance to reach 28d strength, and the maintenance process takes a long time, which is not conducive to construction and road opening. Polymer-based repair mortar: This type of repair material is expensive, which greatly limits the repair area, and the use of a large amount of polymer will reduce the durability of the repair material, and it is prone to peeling and pee...
