Abstract

The invention provides a water-soluble setting accelerator, which is prepared from the following production raw materials in parts by mass: 174 to 212 parts of sodium hydroxide, 226 to 188 parts of aluminum hydroxide, 1 to 8 parts of potassium sulphate and 1 to 8 parts of sodium carbonate. According to a preparation method, firstly, 100 parts of water is contained in a reaction kettle; the sodiumhydroxide is added; heating and stirring dissolution are performed; then, the aluminum hydroxide is added; the continuous stirring and heating are performed to 100 DEG C to 130 DEG C; after the aluminum hydroxide is completely dissolved; the potassium sulphate and the sodium carbonate are added; the stirring is continuously performed; after the complete dissolution, the materials are pumped into aspraying tower by a pump; drying dewatering is performed; the water-soluble setting accelerator is obtained. The water-soluble setting accelerator has the beneficial effects that the materials are solids in the transportation process; the transportation cost is low; the transportation cost is reduced; the defects of easy leakage, too high packaging cost and great storage occupied area in the liquid setting accelerator transportation process are overcome; the preparation process is simple; the production cost is low; no pollution is caused.

Description

technical field [0001] The invention relates to a concrete admixture, in particular to a water-soluble quick-setting agent capable of rapidly setting and hardening concrete and a preparation method thereof. Background technique [0002] The existing quick-setting agent is divided into powder and liquid. Powdered accelerators are insoluble in water and are used in sprayed concrete in the form of powder sprays, causing environmental pollution and damage to the health of operators; liquid accelerators solve the problems of environmental pollution and physical damage, but the current liquid accelerators The coagulant has low content of active ingredients, large dosage, high packaging cost, large storage area, high transportation cost, and is prone to leakage during transportation. Contents of the invention [0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a water-soluble quick-setting agent that does not pollute ...
