Embodiment Construction

[0017] A waste solidifying agent containing modified blast furnace slag is made by mixing the following components in parts by weight (kg):

[0018] Caustic soda 2.2, cement 1.5, gypsum 5.4, triethanolamine 2, alkyl glycoside 2.2, alum 0.8, calcium lignosulfonate 1.2, modified nano blast furnace slag 0.4, sodium chloride 2, magnesium chloride 2, polyacrylamide 2.3, aluminum sulfate 1.8, dicalcium silicate 0.7, tricalcium aluminate 0.8;

[0019] The preparation method of described modified nano blast furnace slag is:

[0020] (1) Calcinate blast furnace slag at 850°C for 4 hours, soak in 12% hydrochloric acid solution for 4 hours, wash with deionized water, soak in 12% saline solution for 4 hours, and then wash with deionized water To neutral, dry, get the treated blast furnace slag for standby;

[0021] (2) Dissolve sodium tripolyphosphate equivalent to 3% of blast furnace slag weight in deionized water, then add 1% of blast furnace slag weight of trioctyl trimellitate, 2.3%...

Abstract

The invention discloses a waste curing agent containing modified blast furnace slag. The waste curing agent is prepared by mixing the following components in parts by weight: 1.4-2.2 parts of caustic soda, 1-1.5 parts of cement, 3.2-5.4 parts of gypsum, 1-2 parts of triethanolamine, 1.3-2.2 parts of alkyl glycoside, 0.6-0.8 part of alum, 0.6-1.2 parts of calcium lignosulphonate, 0.4-1.2 parts of modified nano blast furnace slag, 1-2 parts of sodium chloride, 1-2 parts of magnesium chloride, 1.5-2.3 parts of polyacrylamide, 0.9-1.8 parts of aluminum sulfate, 0.3-0.7 part of dicalcium silicate and 0.6-0.8 part of tricalcium aluminate. In addition to hardening effect of a common curing agent, the waste curing agent containing the modified blast furnace slag further reasonably utilizes the waste and changes the waste into things of value; the hardening effect is strengthened by the nano modified blast furnace slag.

Description

technical field [0001] The invention relates to the field of solid waste recycling, in particular to a waste solidifying agent containing modified blast furnace slag. Background technique [0002] If all kinds of slag and other wastes are not effectively treated and utilized, it will be a heavy burden on the development of enterprises, a serious obstacle to social progress, and the greatest harm to the environment and ecology. The effective recycling, recycling, environmental protection and energy saving of various wastes through high-tech science and technology is the greatest contribution to the protection of human survival and long-term social development. [0003] At present, the curing agents commonly used in the urban construction market cannot promote the harmless and effective treatment of various solid wastes, recycle, recycle, and fail to achieve the effects of environmental protection, energy saving, emission reduction, and circular economy. The invention is a hi...
