Abstract
A cementitious material prepared from carbon steel slag and slag belongs to the field of resource comprehensive utilization. 28-33 weight parts of carbon steel slag, 35-45 weight parts of slag, 4-10 weight parts of fly ash and 18-33 weight parts of desulfurization gypsum are mixed and treated with ball milling to obtain powder with fineness of 0.08mm and a weight of square hole screen residue no more than 6%. The invention utilizes carbon steel slag and slag; cementitious material prepared by the invention can reach quality requirement of 32.5 grade cement; and the preparation process contains no high temperature sintering and has low energy consumption and no pollution.
Description
Technical field
[0001] the present invention relates to a kind of gelling material and using method thereof of utilizing carbon steel slag and slag to make, belong to the comprehensive utilization of resources field.
Background technology
[0002] present, the novel wall material take industrial residue as main material production is more and more, such as gas concrete, concrete segment, autoclaved fly ash brick etc.The consolidating material of these novel wall materials generally all uses cement, lime, its cost accounts for more than 60% of raw materials cost, therefore, research and utilization carbon steel slag and slag are made gelling material, the consolidating material such as place of cement, lime, reduce the cost of novel wall material, improve the economic benefit of enterprise.
Summary of the invention
In order to cut the waste, the present invention proposes a kind of gelling material and using method thereof of utilizing carbon steel slag and slag to make.
A kind of gelling material of utilizing carbon steel slag and slag to make is 28-33 parts of carbon steel slag according to the mass parts proportioning raw materials, 35-45 parts in slag, 4-10 parts in flyash, 18-33 parts of desulfurated plasters.
The above-mentioned raw materials proportioning is obtained the powder that fineness is 0.08mm square hole sieve screen over-size≤6% through mixing, ball milling.
Powder is sealed, packs, seals up for safekeeping, be the gelling material powder.
Admixture is with proportion by weight Na
2SO
430-60 parts, 50-80 parts of NaCl mix, and seal, pack, seal up for safekeeping.
According to gelling material Fen Liao ︰ Wai Jia Ji ︰ water=100 ︰ (proportion by weight of 5-25) ︰ (28-100);
Above-mentioned admixture is added to the water abundant dissolving, obtains admixture solution;
Admixture solution is slowly joined in the gelling material powder, stirred 3-7 minutes, can replace 325 label cement applications.
The present invention can utilize carbon steel slag and slag, adopts production gelling material performance of the present invention to reach the specification of quality of 32.5 label cement, and its preparation process is without high-temperature calcination, and energy consumption is low, and is pollution-free.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with embodiment, but the specific embodiment of the present invention is not limited to following embodiment.
Embodiment;
With carbon steel slag, slag, flyash, the desulfurated plaster ratio (proportion by weight) according to 30:39:5:26, carry out mixing and ball milling, the powder material fineness that obtains is 3%(0.08mm square hole sieve screen over-size 3%).
With Na
2SO
4: the ratio of NaCl=45:55 (proportion by weight) mixes, and makes admixture.
According to the gelling material powder: the proportion by weight of admixture: water=100:10:50,
Above-mentioned admixture is added to the water abundant dissolving, obtains admixture solution;
Admixture solution is slowly joined in the gelling material powder, stirred 3-7 minutes, can replace 325 label cement applications.
Above-mentioned gelling material is carried out the experiment of glue sand.Concrete grammar is referring to GB/T17671-1999.Experiment shows, glue sand ultimate compression strength was 18.9 Mpa in 3 days, and glue sand ultimate compression strength was 38.2 Mpa in 28 days, and its performance has reached the specification of quality of 325 label cement.Presetting period and final setting time were respectively 3 hours 47 minutes and 6 hours 33 minutes.By above-mentioned experimental index, illustrate that the performance of above-mentioned gelling material has reached the specification of quality of 325 label cement.
