Description
Technical field
The present invention relates to a kind of material of construction, particularly, relate to a kind of gelling material, and its preparation method and application.
Background technology
The present domestic novel environment friendly gelling material that is applied to building materials field; Comparatively single (as: people such as Sun Baoyun utilizes blast furnace slag that the Laigang produces to replace cement with 30% volume to employed industrial residue in the raw material; Intensity has reached the requirement that label is 325 ordinary Portland cement); Can not realize the resource utilization of solid waste such as multiple industrial residue simultaneously, and not put on a large scale in the actual buildings build; Even a spot of case history is arranged, also be that some industrial solid wastes are used as concrete little volume additive, do not have to realize solid waste as starting material real the time, and production process approaches zero pollutant emission.
Patented claim CN201010163504.7 discloses a kind of desulfurated plaster-high-calcium fly ash geopolymer gelled material; It is characterized in that: the raw material of this geopolymer gelled material comprises high-calcium fly ass, thermal treatment desulfurated plaster and composite chemical admixture, and wherein: to be desulfurated plaster get at temperature lower calcination 0.5h～1.5h of 600 ℃～800 ℃ the thermal treatment desulfurated plaster; The composite chemical admixture is formulated by sodium hydroxide and liquid sodium silicate, the modulus M (SiO of composite chemical admixture
2)/n (Na
2O) be 1.5～2.0; Quantity relative ratio relationship between these three kinds of raw materials is: the mass ratio of high-calcium fly ass and thermal treatment desulfurated plaster is 9: 1～8: 2; The quality of the Na2O that is introduced by the composite chemical admixture is 10%～15% of high-calcium fly ass and a thermal treatment desulfurated plaster quality sum.These technology materials are more, dealing with complicated, and cost is higher, and the gelling material ultimate compression strength that makes is also lower.
