Embodiment 1

[0026] The fly ash gas-entraining product synergist of the present invention is compounded by the following raw materials:

[0027] HS-109 polycarboxylate superplasticizer: 13.0%;

[0028] Sodium carbonate: 2.0%;

[0029] Sodium tripolyphosphate: 4.0%;

[0030] Self-made modifier: 3.5%;

[0031] Tap water: 77.5%;

[0032] According to the above proportions, put sodium tripolyphosphate into tap water, and after stirring evenly and completely dissolved, add sodium carbonate, polycarboxylate high-efficiency water reducer, and self-made modifier, and then fully stir evenly.

[0033] Preparation method of self-made modifier:

[0034] (1). Base material preparation: Stir triethanolamine, oleic acid, and water at a mass ratio of 1:3:36 for 5 minutes, and keep the temperature at 20°C for about 1 hour;

[0035] (2.) Add triethanolamine having the same quality as the base material and stir for 10 minutes;

[0036] (3.) Add ethylene glycol with the same quality as the base material...

Abstract

The invention discloses a synergist for fly ash aerated products and a preparation method thereof. The purpose of the invention is to provide a synergist for fly ash aerated products, which can improve casting stability, product quality and qualification rate, and preparation thereof. In order to meet the needs of customers and promote the comprehensive utilization of fly ash, the synergist of the present invention contains the following components by mass percentage: polycarboxylate superplasticizer: 13.0%-20.0%; sodium carbonate: 2.0%- 5.0%; sodium tripolyphosphate: 4.0% to 7.0%; modifier: 3.5% to 8.0%; water: 60.0% to 77.5%, put the water into the sodium tripolyphosphate, and after stirring evenly and completely dissolved Then, the sodium carbonate, the polycarboxylate superplasticizer, and the modifier are added in sequence, and the synergist can be obtained by stirring evenly.

Description

technical field [0001] The invention relates to a synergist for fly ash aerated products and a preparation method thereof. During the production process of fly ash aerated products, it is used to adjust the pore structure, promote the matching of slurry thickening and gas generation, reduce the product bulk density, The synergist that improves the strength and uniformity of the product, increases the output per unit, and improves the qualified rate of the product can effectively improve the adverse effects of the unstable quality of raw materials on the production process of fly ash aerated concrete. Background technique [0002] Air-entrained concrete products with fly ash as the main raw material are used as a new type of energy-saving and environmentally friendly wall material. With the advantages of light weight, heat preservation and sound insulation, the industrial waste that originally caused serious environmental pollution hazards—fly ash has been obtained. Comprehen...
