Description

A kind of red mud base rapid hardening injecting paste material administered suitable for sandy soil stratum grouting and reinforcing
Technical field
The present invention relates to a kind of red mud base rapid hardening injecting paste material administered suitable for sandy soil stratum grouting and reinforcing and its preparations Method belongs to waste's reclamation and building materials preparing technical field.
Background technology
The waste residue that red mud is discharged when being aluminium industry extraction aluminium oxide, average often produces 1 ton of aluminium oxide, subsidiary to generate 1.0-2.0 tons of red muds.According to measuring and calculating, nearly 30,000,000 tons of the red mud that China generates every year.The stockpiling of red mud occupies a large amount of soils, right Underground water, soil cause seriously to pollute.Therefore, realize red mud by all kinds of means, large-scale recycling it is extremely urgent.
Sandy soil stratum is as typical soft stratum, with loosely organized, cohesive force is weak, self-stable ability is poor, in dynamic load The features such as easily liquefying under effect becomes the major casualty source for causing tunnel gushing water to dash forward mud.Slip casting is as raising Rock And Soil entirety object It manages mechanical property, realize the impervious important means for reinforcing purpose of country rock, be widely used in the Reinforcement of sandy soil stratum.Note Pulp material is one of key factor of slurry injection technique, increasingly obtains the concern of people.In sandy soil stratum grouting and reinforcing engineering, Cement based grouting material has setting time long, the disadvantage of the property noted difference, though chemical grout consolidation effect is good, has pollution ring Border, it is of high cost the shortcomings of.Therefore there is an urgent need for research and develop a kind of injecting paste material reinforced suitable for sandy soil stratum.The main component of red mud is CaO、SiO2、Al2O3Deng with potential gelation activity.The water of high energy consumption can not only be replaced by preparing cementitious material using red mud Mud base grouting material, additionally it is possible to mitigate the environmental pollution that red mud is brought, promote its resource utilization efficiency.
Currently, have some scholars is used to prepare injecting paste material by red mud, to realize its recycling.Such as Chinese patent Document CN103896503A discloses a kind of red mud base novel injecting paste material and preparation method thereof, by alkali-activator make red mud and Admixture generates a kind of high-strength geo-polymer class injecting paste material；Chinese patent literature CN104446213A disclose it is a kind of with Red mud is the injecting paste material of base starting material, and the intensity of injecting paste material is improved using the compound action of red mud and alkali-activator；China Patent document CN 105669945A disclose a kind of red mud base from suspended flexible injecting paste material, and the material cohesion is strong, and anti-folding is strong Degree is high.These red mud base grouting materials have certain mechanical strength, realize the large-scale application of red mud to a certain extent, but Generally have red mud usage amount low, setting time is long, the feature of the property noted difference.It is not suitable for water-rich sand layer grouting treatment.
Sandy soil stratum injecting paste material is based on superfine cement at present, but cement industry high energy consumption, and superfine cement is expensive, It causes engineering cost high, does not meet green ecological requirement.
