preparation example Construction

[0017] The invention discloses a preparation method of a geopolymer reinforced coagulant. Water is added into a reaction kettle, polyol compounds or sugar compounds are added under low-speed stirring, and the geopolymer reinforced coagulant is obtained by stirring evenly.

[0018] The geopolymer of the present invention uses solid waste or natural minerals as raw materials, has very low energy consumption and discharge of three wastes in the manufacturing process, is environmentally friendly, and is a sustainable "green material". Adding geopolymer reinforced retarder during the use of geopolymer can significantly improve its workability and increase its compressive strength. The setting time can be extended by 1-2 hours, and the 28-day compressive strength can be increased by 20-60%. The amount used is small, 0.1-3% of the weight of the geopolymer. The preparation process is simple, and each component is added into water and stirred evenly during preparation.

Embodiment 1

[0020] 30% deionized water is added to the reaction kettle, 70% glycerin is added under low-speed stirring, and the geopolymer reinforced retarder is obtained after stirring evenly.

Embodiment 2

[0022] Add 60% deionized water into the reaction kettle, add 20% glycerin and 20% glucose successively under low-speed stirring, and get the geopolymer reinforced retarder after stirring evenly.

Abstract

The invention discloses a geopolymer reinforced coagulant, the geopolymer reinforced coagulant is an aqueous solution blended from one or two or more than two of polyhydric alcohol compounds and carbohydrate, and the weight percentages are as follows: 5%-80% of polyhydric alcohol compounds, 0%-80% of carbohydrate, and 10%-90% of water. The invention further discloses a preparation method of the geopolymer reinforced coagulant. The coagulation time of a geopolymer is prolonged, the workability of the geopolymer is improved, the compressive strength of the geopolymer is also strengthened, and the geopolymer reinforced coagulant is well adaptive to various geopolymers, and is used in various geopolymer engineering.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a geopolymer reinforced coagulant and a preparation method thereof. Background technique [0002] Geopolymer is a new type of high-performance gelling material. It is a three-dimensional network inorganic polymer composed of silicon-oxygen tetrahedron and aluminum-oxygen tetrahedron as the skeleton through Al-Si-O bonds. It has a dense structure and has High strength, fast hardening and early strength, high temperature resistance, corrosion resistance, water resistance, low shrinkage, low permeability, non-combustible, heat insulation, heat preservation and many other advantages, in many industrial fields such as transportation and emergency repair engineering, construction industry, metallurgy, ceramics, It has broad application prospects in coatings, nuclear waste treatment, heavy metal element fixation and other fields. In Australia, geopolymers have been used in airports, highw...
