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 has environmental protection, low cost, durable, and the technical feature advantage such as matrix phase capacitive is good, by an extensive class injecting paste material of use.But general inorganic injecting paste material as mortar, cement list liquid slurry etc., is directly built or during pouring construction under rich water condition, conventionally can produce the problems such as segregation, slurry run off, intensity falls sharply, contaminate environment.Therefore, adopt and do not disperse injecting paste material to become the key that solves this type of engineering problem under water.At present, the conventional slip casting material that do not disperse under water, is mainly 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, in performance throwing out, also can cause extending injecting paste material time of coagulation, calculus rate is too low, thereby has weakened the anti-dispersive ability of material, has reduced the efficiency 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 to using ordinary Portland cement as gelling material, polyacrylamide flocculant by adding 0.033%-0.1%, in addition modification of material, obtains the performance that water resistant is disperseed.The setting and harden speed of silicate cement own is slower, and the delayed coagulation of polyacrylamide in addition makes the time of coagulation of injecting paste material long, so it can not or have under the condition of quick setting and rapid hardening requirement at moving water and uses.
Document 2 < < underwaters do not disperse the application > > (Chen Jian of grouting material in Donghai Bridge, 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 consist of silicate cement, river sand and concrete underwater undispersing agent, anti-dispersiveness when water cement ratio is 0.5 in hydrostatic is better, mobility better, the intensity of 28 days can reach 22.6MPa, but its final setting time reaches 16h30min.Longer time of coagulation is constructed this material in circumstance of flowing water, and requires to use under rapidly solidified condition, has obvious limitation.
Document 3 < < do not disperse to be under water in the milk the application > > of novel material in karst impervious leakage-stopping (" Liang Xuewen, Li Shangyou. Guangxi hydropower .2008(3): 5-7. ") in disclose a kind of underwater and do not disperseed injection material.This grouting material is to consist 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 impervious leakage-stopping engineering, has established material foundation.But due to the restriction that formed by material prescription, this grouting material does not have performance advantage aspect intensity, be mainly manifested in that intensity is low and tempo is slow, from document, provide test result, the 28d intensity of most of prescriptions is lower than 10MPa, lower intensity level, is restricted the application of the aspects such as this material is repaired under water, fixed filling, engineering protection.
