Abstract
The invention discloses masonry mortar used in an underwater alkaline environment. The masonry mortar comprises the following components, according to a weight ratio, 180-220 parts by weight of Portland cement, 30-50 parts by weight of special cement, 705-715 parts by weight of natural medium sand, 13-18 parts by weight of resin glue powder, and 30-40 parts by weight of a special additive. The special additive is mixed from 2-5 parts by weight of a thickening agent, 0.5-1 part by weight of a super-plasticizer, 5-8 parts by weight of a thixotropic agent, 12-15 parts by weight of an adjusting admixture, and 5-8 parts by weight of an early strength agent. The masonry mortar is adjusted by high-performance additives special for underwater masonry mortar, and resin materials good in alkaline resistance are added, so that the masonry mortar is prevented from undergoing a reaction in the alkaline condition, and hardening and mortar performance aren't affected. At last, the masonry mortar is not prone to disperse, good in construction, resistant to alkaline, normal in underwater hardening, and high in strength in a working condition with water.
Description
Technical field
The present invention relates to one kind alkaline environment masonry mortar under water.
Background technology
, under having water state or high disturbance, slurry can easily isolate after meeting water for cement mortar or concrete（Cement is easy to run off,
Sand material is easily separated）, simultaneously some components can participate in the basic conditions reacting, thus affecting to harden and concrete or mortar
Performance.In the past underwater concrete building build or damage reparation typically using building cofferdam, drain water, then placing concrete or
Masonry panel, motar are completing.This kind of engineering have the shortcomings that time-consuming, take a lot of work and expensive.Second method is using slipping
Groove, conduit, pump, drive bottom container etc. and normal concrete or mortar are transported to underwater casting or repair position and to complete.But the
The common underwater concrete that two kinds of methods are adopted or mortar are met water and are easily isolated, thus affect to harden and concrete or mortar property
Can, not as draining the method quality height that water is watered or repaired.
Draw water for overcoming routine to build cofferdam and construct again and both underwater castings that material property is bad or method for repairing and mending
Deficiency, (non-dispersible un-derwater concrete, is abbreviated as to have been developed over non-dispersible underwater concrete
NDC), carry out pouring or repair and can not building cofferdam of underwater concrete building with it, do not drain water, directly enter in water
OK, and quality is reliable.Non-dispersible underwater concrete is to add some additional components in common underwater concrete, thus
Concrete is made to have a certain degree of dispersion resistance before obtaining hardening under water.And having the underwater concrete thin layer of certain flow rate
Repair or build by laying bricks or stones in plastering, then need with not disperseing hard mortar (abbreviation NDM) soon under water.Do not disperse under water soon hard mortar by cement
Mortar mixes special additive and forms.
Though existing public technology lists some technology path of masonry mortar special additive, proportionings and mutually speak on somebody's behalf under water
Bright, but effect is general in actual use, and there is no clear and definite construction technology and product and construction technology explanation, result in reality
Border using effect and having little significance.
Content of the invention
It is an object of the invention to provide one kind alkaline environment masonry mortar under water, to solve existing cement mortar in alkalescence
Under the conditions of participate in reaction, impact hardening and concrete or mortar performance issue.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：One kind alkaline environment masonry mortar under water, by with
The component of lower weight proportion is constituted：Ordinary cement 180～220 weight portion；Special cement 30～50 weight portion；Nature medium sand 705
～715 weight portions；Resin rubber powder 13～18 weight portion；Special additive 30～40 weight portion；Described special additive is by thickening
Agent 2～5 weight portion；Super plasticizer 0.5～1 weight portion；Thixotropic agent 5～8 weight portion；Adjustable solidification agent 12～15 weight portion；Early strength agent 5
～8 weight portions mix.
Preferably, described special cement is made up of the component of following weight proportion：Sodium acetate 3～6 weight portion；Flyash
5.5～8.5 weight portions；Sodium lignin sulfonate 0.8 weight portion；Portland cement 55～68 weight portion of intensity 42.5.
Preferably, described thickening agent is selected from one of cellulose, cellulose ether, synthetic resin and synthetic resin derivant
Or it is several.It is highly preferred that described cellulose ether is hydroxypropyl methyl cellulose ether or ethoxyl methyl cellulose ether.
Preferably, described super plasticizer is selected from one of sulfate resin and sulfonate or two kinds.
Preferably, described thixotropic agent is selected from the layer silicate mineral of modified alta-mud, montmorillonite and aluminium-magnesium silicate
One or more.
Preferably, described adjustable solidification agent is made up of the component of following weight proportion：Anhydrous citric acid 13～17 weight portion, anhydrous
Sodium pyrophosphate 28～32 weight portion, sodium tripolyphosphate 2.5～3.5 weight portion, pre-gelatinized starch 2～6 weight portion, sodium bentonite
28～30 weight portions, inorganic silicic acid magnalium gel 2.2～2.8 weight portion.
Preferably, described early strength agent is made up of the component of following weight proportion：Alkali metal bromide 13～26 weight portion；Partially
Sodium aluminate 26～36 weight portion；Alkali metal hydroxide 25～45 weight portion；Silica 1 8～25 weight portion；Alcaminess are organic
Thing 1.8～2.5 weight portion；Described alkali metal bromide is one of NaBr, KBr, LiBr, and described alkali metal hydroxide is
NaOH or KOH, described hydramine type organic is triethanolamine or triisopropanolamine.
Special additive of the present invention has following two usings method：
1st, by mortar factory according to the ratio of additive designing, produce masonry mortar special additive under water, this additive is pure
Powder body material, after automatic equipment physical mixed, scene is proportionally spiked in the masonry cement mortar designing,
Proportionally add water after stirring using.
2nd, according to actual building site situation and needs, special outer according to masonry cement mortar and under water masonry mortar by mortar factory
Plus the proportioning of agent, the premixing mortar of quality of production stable homogeneous in factory, after transporting scene, ratio as requested adds water
After stirring using.
The invention has the beneficial effects as follows：
By a kind of special additive adjustment of masonry mortar under high-performance water, it is simultaneously introduced alkaline resistance properties preferable resinae material
Material, it is to avoid masonry mortar component reacts in the basic conditions, the performance of impact hardening and mortar, final make to build sand by laying bricks or stones
Slurry has the advantages that to be difficult dispersion, good construction under the conditions of submersible, alkaline-resisting, normal hardening and intensity are high under water.
In special additive, thickening agent can increase the cohesiveness of mixing thing, thus giving dividing regardless of loose sand slurry is anti-under water
Scattered, education resistance energy.Super plasticizer can increase fluidity and the workability of mixing thing, thus give material preferably Self-leveling,
Self-compacting ability.Conventional super plasticizer is mainly sulfate resin and Sulfonateses, and why such material has to resist under water is divided
The performance dissipating and not isolating.By the admixture of special cement and the collective effect of adjustable solidification agent, impart such material early-strong-fast-hard
Performance.By adjusting the consumption of the type, volume and special cement and adjustable solidification agent of thickening material in additive it is ensured that mix
Good mortar, during band water transmission, will not occur segregation phenomenon；Meanwhile, submersible has preferable application property,
Having under water and state of disturbance can not be discrete, and short-term quickly forms and hardens well, and later strength conservation rate is preferable.
