Description
Technical field
The present invention relates to a kind of inorganic slip casting plugging material, belong to plugging material technical field.
Background technology
Injecting paste material is to improve for the purpose of ground, plays and fill crack, stratum, hole the effect of consolidation in ground.It is the solid formed after certain chemistry or physical reaction by slurries, and the transformation again to Seed harvest from liquid phase to solid phase occurs in slip casting process, for filling crack in stratum or hole.
In the dam foundation construction process of water conservancy and hydropower station, often there will be piping, water yield is comparatively large, needs the timely shutoff of the dam foundation.The direct plugging effect of cement grout of general employing is not obvious, and this is mainly because the time of theing cement solidifies is longer, cement grout affects it after being broken up dilution by current and solidifies and plugging effect.Regulate the time of coagulation of cement, keep cement slurry do not disperse under flow action thus ensure that plugging effect is undoubtedly technological difficulties.
If publication number is CN101353261 in prior art, name is called the patent of invention of " waterproof fireproofing inorganic plugging material ", plugging material disclosed in this patent comprises plaster of Paris 40 ~ 56, I level by weight or II level flyash 0 ~ 20, ground blast furnace slag and ordinary Portland cement 24 ~ 40, methyl cellulose ether 0 ~ 1, calcium stearate or Zinic stearas or their mixture 0 ~ 3, Citric acid monohydrate Food grade 0 ~ 0.1, quartz sand 0 ~ 300, glass bead 0 ~ 75, expanded vermiculite 0 ~ 75; Have waterproof fireproofing superior performance, fast solidifying, early strength rapid development, later strength is moderate, is convenient to remove, and construction is simple, with mix with, time of coagulation can arbitrarily adjust, and stores convenient transportation, the advantages such as environmental protection.The weight that expansion microballon and expanded vermiculite carry out lightening material is have employed in this patent, but make the intensity of material greatly decline equally, and process in the construction of the water conservancy and hydropower dam foundation problems such as piping need condensation of materials to harden after intensity high and hardening structure body fine and close, therefore this material can not meet user demand.
Summary of the invention
The intensity that the present invention is intended to solve plugging material in prior art is not high, use the problem be restricted, a kind of inorganic slip casting plugging material is newly proposed, be main material by selecting Portland clinker, and add the raw material such as slag, aluminosulfate cement, wilkinite, hydroxyethyl ether cellulose of specified proportion, the material made have have good workability, plugging effect is good, intensity is high advantage.
In order to realize foregoing invention object, technical scheme of the present invention is as follows:
A kind of inorganic slip casting plugging material, is characterized in that: comprise following raw material by weight: Portland clinker 75 ~ 90 parts; 3 ~ 10 parts, slag; Aluminosulfate cement 5 ~ 15 parts; Wilkinite 0.5 ~ 4 part; Hydroxyethyl ether cellulose 0.05 part ~ 0.2 part; Water reducer 0.25 ~ 0.5 part; Quilonum Retard 0.005 ~ 0.1 part; Defoamer 0.05 ~ 0.5 part.
In order to realize the present invention better, the specific surface area of described slag is 400 ~ 800kg/m3.
