Embodiment 1

[0028] Embodiment 1: select precipitant unslaked lime, calcium carbide slag as the component of the present invention, pulverize by hammer mill, mix evenly, promptly prepare the phosphorus slag activation modifier of the present invention, during use, add this phosphorus slag in phosphorus slag The activated modifier is ground and mixed uniformly by a ball mill and put into use as the cement dosage, which can effectively eliminate the phenomenon of retarded setting and retarded strength of phosphorus slag.

Embodiment 2

[0029] Embodiment 2, select 30% lime slag, 20% calcium carbide slag as precipitating agent, select 50% coal cinder as filler again, grind and mix by ball mill, just add in grinding head, promptly make A of the present invention Phosphorous slag activation modifier.

Embodiment 3

[0030] Embodiment 3 selects 30% slaked lime for use as precipitating agent, selects 20% sodium sulfate, 10% calcium chloride as catalytic activator again, selects 40% fly ash for use as filling powder, pulverizes, mixes uniformly, promptly makes This invention relates to the B-type phosphorus slag activation modifier.

Abstract

The phosphorous slag activating modifier is precipitant comprising one or several kinds of oxide, hydroxide, chloride and nitrate of Ca, Mg and Ba, and prepared through crushing. It is added into phosphorous slag to convert the slowly coagulating components in phosphorous slag into insoluble precipitate as stuffing component. The present invention makes it possible to utilize phosphorous slag to produce high-quality and low-cost cement and other building material.

Description

technical field [0001] The invention relates to a composition in the new technology of industrial waste slag utilization, in particular to a composition in the new technology of industrial electric furnace phosphorus smelting waste slag-phosphorus slag utilization, which can effectively eliminate the slow setting and slow strength of phosphorus slag and has catalytic activation for phosphorus slag , The composition of grinding aid. Background technique [0002] my country is rich in phosphate rock resources and has become the largest phosphating chemical production base in Asia. For example, Guizhou, Yunnan, Hubei, Sichuan and other places have huge scale and development potential of phosphate chemical industry, followed by the annual discharge of phosphorus slag reaching one million tons . Although phosphorus slag contains a large amount of minerals such as calcium silicate, calcium aluminate, and calcium aluminate, it is a very valuable industrial waste slag resource. The...
