Description

The coral aggregate reinforcing slurries of chlorion can be cured in a kind of phosphor aluminate cement base
Technical field
The coral aggregate that chlorion can be cured the present invention provides a kind of phosphor aluminate cement base strengthens slurries.
Background technology
For far from the engineering construction on the island of land, required raw material are required to go over from transcontinental shipments, transport in this way Defeated cost is very high.If can gather materials on the spot, raw material can be solved the problems, such as.China possesses wide marine site, this The islands and reefs being much made of coral reef are distributed in a little marine sites.Some researches show that the main component of coral reef is aragonite and high magnesium side Xie Shi, total ingredients calcium carbonate content reach 96% or more.If bone is made by a series of manufacture crafts in these coral reefs Material is used for concrete batching, has very important Practical significance to the engineering construction on China island.So far there are many grind Personnel are studied carefully to the direct using a large amount of research work has been done of coral aggregate, if number of patent application is CN201610973322.3 mono- The seawater coral aggregate concrete building block of the anti-accumulation of salt in the surface soil of kind, the invention consolidate salt agent to cure invading in coral using addition coral aggregate Corrosion ion, the invention may be implemented coral as aggregate indirect application, but there is no aggregate is directly handled, make Coral aggregate application range becomes smaller;Number of patent application is a kind of seawater coral aggregate concretes of CN20160274695.1, by outer Add agent such as consolidate salt agent, antifoaming agent come eliminate coral aggregate carrying erosion carbon dioxide and in producing concrete due to slurry The bubble that the gap of coral aggregate generates is squeezed, but the effect of this method is limited, it doesn't solve the problem fundamentally.And this The coral aggregate that chlorion can be cured in a kind of phosphor aluminate cement base that invention provides strengthens slurries, can fundamentally solve to ask Topic can solve two hang-ups of coral aggregate application, can be cured and strengthen coral aggregate, have extremely wide application prospect.
Invention content
For problems of the prior art, the present invention provides a kind of phosphor aluminate cement bases, and chlorion can be cured Coral aggregate strengthens slurries.
The present invention uses following technical scheme:
The coral aggregate reinforcing slurries of chlorion can be cured in a kind of phosphor aluminate cement base, it includes that infiltration slurries and 22 cover Slurries two parts;It is described infiltration slurries mass percentage composition be:Phosphor aluminate cement 70%~85%, penetrant crystalline material 1%~4%, clay matter mineral admixture 10%~25%, adjustable solidification agent 0.4%~2%, the ratio of mud are 0.6~0.75;The packet The mass percentage composition for covering slurries is:Phosphor aluminate cement 70%~85%, is adjusted clay matter mineral admixture 10%~25% Solidifying agent 0.4%~2%, the ratio of mud are 0.5~0.6.
The clay matter mineral admixture is at least one of gold ore tailing, white Tungsten tailing.
The specific surface area > 298m of the gold ore tailing2/ kg, the percentage of sieve residue < 5% of 200 mesh of white Tungsten tailing sieve.
The strength grade of the phosphor aluminate cement is not less than 42.5 grades, surface area > 320m2/kg。
The specifically used method for strengthening slurries is as follows:
1) by prefabricated infiltration slurries injection kiln basin, coral aggregate to be processed is put into kiln basin and is impregnated Then 5min pulls coral aggregate out from kiln basin;
2) aggregate pulled out is stood into 1h~2h, can carries out in next step, permeating the thickness of slurries cladding at this time after air-drying For 0.3mm~0.5mm;
3) cladding slurries injection is sprayed in mortar machine, the coral aggregate that will be obtained by step 2) processing is put into vibrating screen In, it divides as the thickness of a particle;
4) vibrating screen is opened, starts spray coating slurries, a batch is changed after 1min;By processed coral aggregate Stand 30min~1h, at this time coat slurries cladding thickness be 0.5mm~1mm, as phosphor aluminate cement base can be cured chlorine from The coral aggregate of son.
The penetrant crystalline material is the product of XYPEX series, and ingredient includes cement, quartz sand, water and activity chemistry object Matter.The penetrant crystalline material that the present invention uses is bought in Canadian XYPEX series penetrant crystalline material, and ingredient includes water Mud, quartz sand, water and active chemistry.
Infiltration slurries used in the present invention ratio of mud itself is larger, good fluidity, can effectively fill up coral aggregate Gap, and the XYPEX series penetrant crystalline materials in slurries are permeated, it contains cement, quartz sand and active chemistry And water, cement, quartz sand and infiltration slurries in clay matter mineral admixture can be used as reactant provide Ca2+And SiO3 2- It can react with unhydrated or insufficient aquation cementitious material, generate C-S-H gels, can effectively fill up remaining Micro-pore;Active chemistry in penetrant crystalline material includes compound additive (by water-reducing agent, hydrophober, swelling agent group At) and anionic catalyst (contain active SiO3 2-Ion), compound additive is dissolved in after water polymerization under certain condition and increases, Or chemically reacted with the ion in inside concrete hole solution, it generates crystalline solid not soluble in water and blocks crack and capillary Hole, or react with substances such as calcium hydroxide, aluminium hydroxides in concrete, insoluble needle-shaped ettringite is formed, outside Add agent that will largely be consumed at hydration reaction initial stage;Active anion catalyst can occur with the calcium ion in concrete Chelation forms short-term soluble complexes, but easily captures calcium ion by silicate, aluminate, is formed more stable insoluble Object, later active material can form new free radical again, chelated again with calcium ion, then repeat this process, not only can be with Promote aquation, and the progress chemically reacted under low reaction concentration can be promoted, generates C-S-H gels, also can effectively fill up The place that cement slurry is not filled.In conclusion this infiltration slurries can more effectively be filled up inside coral aggregate Hole improves the mechanical property of coral aggregate.
The cladding slurries of the present invention can be fixed the chlorion in coral aggregate by two ways, and one is physics Absorption:Micropore in cement slurry can fix chlorion by way of physical absorption;Another kind is chemical reaction method:Cladding The main component of slurries is phosphor aluminate cement, containing a large amount of calcium aluminates, and is also contained in clay matter mineral admixture a large amount of Alundum (Al2O3) can occur chemical reaction with chlorion and generate Friedel salt (3CaoAl2O3·CaCl2·10H2O) and Kuzel salt (3CaoAl2O3·0.5CaSO4·0.5CaCl2·10H2O), a large amount of chlorion, while both can be cured The generation of salt can also optimize slurry pore structure, improve compactness.And due to there is hydrated product generation, moreover it is possible to make cladding slurries with Coral aggregate combines even closer, not easily to fall off, and it is phosphor aluminate cement, phosphorus aluminic acid to coat the main component in slurries The intensity of salt cement is very high, and the intensity of coral aggregate can be improved after package coral aggregate.And permeate the main component of slurries It is also phosphor aluminate cement, it equally can be in the internal curing chlorion of aggregate.
It is an advantage of the invention that:By coral aggregate after the cladding slurries of the present invention and infiltration slurries intensive treatment, Mechanical strength is significantly improved, and best crush values test result shows≤18%, can directly be used as general aggregate, There is boundless application prospect.Chlorion and internal exhausted big portion have been eliminated for the more original aggregate of coral aggregate Divide gap, solves puzzlement direct applied two hang-up of coral aggregate, have a extensive future.
