Description
Technical field
The invention belongs to building material technical field, especially relating to a kind of take flyash as fast solidifying anti-corrosion cement of raw material and preparation method thereof.
Background technology
Cement is as the maximum artificial material of building, water conservancy and transportation building engineering consumption, its production process needs to consume large quantities of lime stone, clay and fuel and electric power, be the material of a kind of high resource and high energy gamma source consumption and high-temperature chamber gaseous emission, seek new raw material resources and preparation method that is alternative or that can be used as supplementary new cement is the problem that material supplier author is devoted to solve always.Along with the area of Development control area and the continuous expansion in field, the construction work being in special physical environment also proposes different new requirements to the performance of cement, and the demand with the cement of property increases day by day.On the other hand, all types of industries waste residue is still a problem not yet thoroughly solved, comprising the flyash that thermal power generation corporations discharge to the disadvantageous effect of environment and effective disposal.Although the large part of flyash that power plant's dry method is discharged in recent years is utilized, but a large amount of flyash of wet method discharge over the years, because its general granularity is thicker, carbon content is higher, its physical properties and reactive behavior can not meet the requirement as cement mixture and concrete admixture, directly can not be applied in large quantities in cement and concrete and other building material made, not yet can be used effectively and be stored up for a long time.Flyash store up not only land occupation, go back severe contamination surrounding environment, therefore its efficient resource utilization is a problem demanding prompt solution.Being that main raw material prepares cement with storing up flyash, can saving the Nonrenewable resources such as Wingdale and clay, liberation soil is used for industry and commerce exploitation and dwelling construction, and energy-conserving and environment-protective.But existing coal ash for manufacturing for the technology of cement exist flyash consumption few, height is required to quality of fly ash, as when producing Portland fly ash cement, flyash research on maximum utilized quantity is only 40%, and have harsher requirement, the problem that when doping quantity of fly ash is larger, cement performance is poor to the loss on ignition of flyash with active.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, providing a kind of take flyash as fast solidifying anti-corrosion cement of raw material and preparation method thereof, this soon solidifying anti-corrosion cement can rapid solidification, corrosion resistance nature strong.
The present invention is by the following technical solutions:
Take flyash as a fast solidifying anti-corrosion cement for raw material, comprise the synthetic material 75 ~ 85 parts of parts by weight, Portland clinker 10 ~ 20 parts, 5 ~ 8 parts, gypsum, adjustable solidification agent 0.1 ~ 1.0 part and water reducer 0.3 ~ 0.7; The raw material of described synthetic material comprises 60 ~ 75 parts, the flyash of parts by weight, slaked lime 25 ~ 40 parts, alkali-activator 0.5 ~ 1.5, sulphate activation agent 1 ~ 2 part and 20 ~ 25 parts, water.
As preferably, described alkali-activator is alkali metal hydroxide or alkaline carbonate.
As preferably, described sulphate activation agent is saltcake or gypsum.
As preferably, described gypsum is at least one in dihydrate gypsum, semi-hydrated gypsum, dehydrated gyp-.
As preferably, adjustable solidification agent is at least one in Trisodium Citrate, sodium polyphosphate, Sunmorl N 60S.
As preferably, water reducer is methylene radical dimethyl sodium dinaphthalenesulfonate polymkeric substance or sodium lignosulfonate.
As preferably, water reducer is Powdered.
Fast solidifying anti-corrosion cement of the present invention take flyash as raw material, reduces environmental pollution, and not high to the quality requirements of flyash, takes full advantage of scrap feed material, energy-conserving and environment-protective.
Above-mentioned take flyash as the preparation method of the fast solidifying anti-corrosion cement of raw material, comprises the following steps:
The first step: take each raw material, by flyash, slaked lime, alkali-activator, sulphate activation agent mixing, grinding to 80 μm tails over and is less than 5%, obtains admixtion;
Second step: by described admixtion and water mixing, stir, make the pellet that diameter is 8 ~ 12mm;
3rd step: described pellet is obtained steam-cured material in 10 ~ 16 hours 95 ~ 98 DEG C of vapor cures;
4th step: described steam-cured material after 15 ~ 90 minutes, is cooled to obtain synthetic material at 750 ~ 1000 DEG C of temperature lower calcinations;
5th step: by described synthetic material 75 ~ 85 parts, Portland clinker 10 ~ 20 parts, 5 ~ 8 parts, gypsum, adjustable solidification agent 0.2 ~ 1.0 part, water reducer 0.3 ~ 0.7 part mixing, grinding to 80 μm tails over and is less than 4%.
As preferably, air cooling or air-cooled is blown in being cooled to of the 4th step.
Ultimate principle of the present invention makes active silica and active oxidation reactive aluminum in lime and flyash form hydrated calcium silicate and drated calcium aluminate by hydrothermal treatment consists, forms Dicalcium Phosphate (Feed Grade) and seven aluminium ten dicalcium at a lower temperature after calcining.Wherein seven aluminium ten dicalcium have very high hydration activity, and Dicalcium Phosphate (Feed Grade), also owing to being formed at a lower temperature, exists a large amount of textural defect, therefore also has very high hydration activity, and easy and water reacts the hydrated product being formed and have good cementing property.
Neutral and alkali exciting agent of the present invention can with the alumina silicate glass precursor reactant in flyash, destroy vitreum network structure, reduce the extent of polymerization of vitreum network structure, greatly improve the speed of reaction of wherein silicon oxide and aluminum oxide and lime and the rate of formation of hydrated calcium silicate and drated calcium aluminate, and then improve the content of gelling material mesosilicic acid dicalcium and seven aluminium ten dicalcium, improve the gelling of gelling material; In the present invention, sulphate activation agent can impel the reaction of aluminum oxide and lime to form hydrated calcium aluminate sulfate in hydrothermal reaction process, thus promotes the stripping of aluminium in vitreum.
In the present invention, gypsum can react with seven aluminium ten dicalcium and water and form the very high calcium trisulphoaluminate hydrate of gelling, improves strength of cement; Portland clinker can improve the Ca of early water slurry body
2+ionic concn, can improve the intensity of cement, especially early strength; Retardant can regulate the speed of reaction of seven aluminium ten dicalcium thus make to be unlikely to too short the time of coagulation of the gelling material of cement and impact construction, and water reducer can reduce the water requirement of cement, thus improves the intensity of Behavior of Hardened Cement Paste.
Beneficial effect of the present invention is:
(1) cement of the present invention is large to the utilization ratio of the high low-quality flyash of carbon content, can solve the problem of flyash to land occupation, contaminate environment.
(2) the present invention is by alkali-activator and sulphate activation agent compound only use, effectively can promote the reaction between each component in steam-cured process pellet, reduce steam-cured hear rate, shorten the steam-cured time, improves productivity effect and equipment use efficiency;
(3) preparation method of cement of the present invention is simple, and calcining temperature is low, and greenhouse gas emissions are few;
(4) cement of the present invention has quick setting and rapid hardening, characteristic that high, the resistance to vitriol aggressiveness of intensity is good, be specially adapted to tunnel, under water, saline and alkaline area and coastland engineering.
