Description
Technical field
The invention belongs to civil construction material technology field, relate to and do not disperse to coagulate soon inorganic injecting paste material of type and preparation method thereof under water.
Background technology
Relatively with organic materials, inorganic injecting paste material have environmental protection, low cost, durable, with technical feature advantages such as the matrix consistency is good, by a class injecting paste material of extensive usefulness.But general inorganic injecting paste material as mortar, cement list liquid slurry etc., is directly built under rich water condition or during pouring construction, can produce usually that segregation, slurry run off, problems such as intensity falls sharply, contaminate environment.Therefore, adopt the key of not disperseing injecting paste material to become this type of engineering problem of solution under water.At present, the slip casting material that do not disperse under water commonly used mainly is by adding organic polymer coargulator, improve injecting paste material flocculation, protect and mould ability, make material obtain under water not dispersing property.But organic polymer coargulator also can cause prolonging injecting paste material time of coagulation, the calculus rate is low excessively in the performance throwing out, thereby the anti-dispersive ability of the material that weakened has reduced the efficient of mortar depositing construction.The Grouting engineering of, snap cure rapidly solidified for requiring particularly, the application of this type of material is restricted.
Document 1 discloses a kind of underwater grouting material (application number: 200610033878.0 of cement concrete, publication number: 101024567, open day: 2007-08-29), this invention is as gelling material with ordinary Portland cement, polyacrylamide flocculant by adding 0.033%-0.1% obtains the performance of anti-water-dispersion in addition modification of material.The setting and harden speed of silicate cement own is slower, and the delayed coagulation of polyacrylamide in addition makes that the time of coagulation of injecting paste material is long, so it can not or have under the condition of coagulating fast hard requirement soon at moving water and uses.
Document 2 " the novel application of material in Donghai Bridge that do not disperse under water to be in the milk " (Chen Jian, village heroes, Lu Anqi etc. concrete and cement products .2004(3): 18-20) a kind of grouting material that do not disperse is under water disclosed.This grouting material is to be made of silicate cement, river sand and concrete underwater undispersing agent, and the intensity better, mobile better, 28 days of the anti-dispersiveness when water cement ratio is 0.5 in hydrostatic can reach 22.6MPa, but its final setting time reaches 16h30min.Long time of coagulation, make this material in circumstance of flowing water, construct, and require to use under the rapidly solidified condition to have tangible limitation.
Document 3 " the novel material application in karst reservoir impervious leakage-stopping does not under water disperse to be in the milk " (" Liang Xuewen, Li Shangyou. Guangxi hydropower .2008(3): 5-7. ") in a kind of novel injection material that do not disperse is under water disclosed.This grouting material is to be made of cement, modified polyvinyl alcohol, water glass, flyash, has good dispersive ability not under water.By ratio optimization, this material can obtain good gel time adjustability, i.e. gel time 1min-700min, and the calculus time of material is shorter, is generally 1h～24h.The gelation time adjustability that this material is stronger has broken through traditional inorganic grouting material in the deficiency aspect time of coagulation, for the widespread use of inorganic grouting material in the impervious leakage-stopping engineering, has established material foundation.But because the restriction that constituted by the material prescription, this grouting material does not have performance advantage aspect intensity, show that mainly intensity is low and tempo is slow, provide test result as can be known from document, the 28d intensity of most of prescriptions is lower than 10MPa, lower intensity level makes the application of aspects such as this material is repaired under water, fixed filling, engineering protection be restricted.
