Embodiment 1

[0055] The embodiment of the present invention provides a kind of gypsum-based composite hydraulic solidifying agent, its component and content are:

[0056] Cement 17%

[0057] Fluorogypsum 25-33%

[0058] Fly Ash 50-57%

[0059] High magnesium lime 3-5%

[0060] Sodium thiosulfate or inorganic ammonium salt 2-4%

[0061] The above percentages are percentages by weight.

[0062] Wherein, sodium thiosulfate or inorganic ammonium salt is activator A, preferably sodium thiosulfate.

[0063] In the process of mixing the gypsum-based composite hydraulic solidifying agent with construction sand to prepare the gypsum-based composite hydraulic solidified block, activator A can increase the solubility of gypsum to generate highly dispersed calcium sulfate, which reacts with calcium hydroxide in the system, It is easier to form hydrate products such as ettringite with fly ash; at the same time, after hydrolysis, the OH- concentration in the solution can be increased, which promote...

Abstract

The invention discloses a gypsum-based composite hydraulic curing agent and a gypsum-based composite hydraulic curing block, which relate to the field of gypsum-based composite hydraulic gel materials. The gypsum-based composite hydraulic curing agent comprises the components of cement, gypsum and active chemical substances A and B (metal salt, alkali metal salt and alkaline-earth metal salt). The gypsum-based composite hydraulic curing agent is used for preparing the gypsum-based composite hydraulic curing block.

Description

technical field [0001] The invention relates to a gypsum curing agent, in particular to a gypsum-based composite hydraulic curing agent and a gypsum-based composite hydraulic curing block. Background technique [0002] With the rise of a large number of high-tech industries in the 21st century, the sustainable development strategy has become a theme of social development. It is necessary to develop new materials from the perspective of energy saving, resource saving, and recycling, and vigorously develop circular economy. A large amount of solid waste such as fly ash, desulfurized gypsum, fluorine gypsum, phosphogypsum, high magnesium lime, etc. are discarded and stockpiled, occupying a large amount of land, polluting air and water sources, and posing a threat to the ecological environment on which human beings depend. , resulting in a serious waste of funds and land resources, but also wasted a lot of high-quality resources. The gypsum-based composite hydraulic curing agen...
