Description

A kind of hydraulic cementing materials and preparation method thereof
Technical field
The invention belongs to building material field, be specifically related to a kind of hydraulic cementing materials and preparation method thereof.
Background technology
At present, the cement consumption of building mortar accounts for 25%～35% of whole construction work cement consumption, usually all be to use the cement preparation building mortar of 32.5 strength grades, in order to guarantee the workability of mortar, the consumption of cement is often bigger, usually cause waste, be unfavorable for saving energy and reduce the cost and reducing cost.
Wingdale is the main raw material of manufacture of cement, normally Wingdale and clay, iron powder powder mix is worn into raw material and is sintered into cement clinker, allocates the blended material grinding again into and becomes cement.Limestone calcination not only needs to expend a large amount of energy, also can emit a large amount of carbon dioxides.
Utilize the blended material of natural low-cost resource Wingdale as cement, compare with slag, flyash, because of its storage capacity is big, resource distribution is wide, and is cheap, and convenient transportation need not be dried, and Cement industry is had bigger economic worth.A large amount of experiment confirms, a spot of Wingdale not only plays the micro-aggregate filling effect in cement, improve the grain composition of cement and the pore structure of cement stone, and the early hydration of silicate cement is had promoter action.Can improve the early strength of cement, strengthen the interface bonding between limestone aggregate and cement slurry simultaneously.But along with Wingdale volume in the cement is increased to certain degree, cement intensity sharply descends, and is difficult to satisfy the requirement that cement uses.Therefore, in existing manufacture of cement, Wingdale is not high as the addition content of cement mixture, generally below 25%.
Summary of the invention
The object of the present invention is to provide high hydraulic cementing materials of a kind of limestone content and preparation method thereof, this method technology is simple, cost is low.
To achieve these goals, technical scheme of the present invention is: a kind of hydraulic cementing materials, it is characterized in that it is mixed by Wingdale, industrial residue, gypsum and admixture raw material, the shared mass percent of each raw material is: Wingdale 35%～75%, industrial residue 5%～50%, gypsum 0%～10%, admixture 0%～20%, the shared mass percent of gypsum and admixture is not 0 simultaneously, and the shared mass percent sum of each raw material is 100% (satisfying 100%).
Described Wingdale is with lime carbonate (CaCO 3) be the natural crystal of main component.
Described industrial residue is: blast-furnace slag, slag, flyash or coal gangue; Its main chemical ingredients is: silicon-dioxide (SiO 2), aluminium sesquioxide (Al 2O 3), calcium oxide (CaO), magnesium oxide (MgO), manganese oxide (MnO), ferric oxide (FeO) and sulphur etc.
Described gypsum is with calcium sulfate (CaSO 4) be anhydrite, dihydrate gypsum, semi-hydrated gypsum or the chemical gypsum (phosphogypsum, fluorgypsum or salt gypsum) of main component.
Described admixture is: lime (main component CaO comprises chemical industry lime), calcium hydroxide (Ca (OH) 2), any one or any mixing that (contains any two kinds) more than two kinds in the highly basic, highly basic salt, cement clinker (is the Portland clinker of main component with Calucium Silicate powder, calcium aluminate, iron calcium aluminate), be any proportioning during any mixing more than two kinds.
Described highly basic is the alkali that contains potassium ion or sodium ion (be KOH, NaOH or with K, other alkali of Na ionic); Described highly basic salt is the alkali salt that contains potassium ion or sodium ion (be sodium sulfate, vitriolate of tartar, yellow soda ash, salt of wormwood or mainly contain K or other highly basic salt of Na ionic).
The shared mass percent the best of described each raw material is: Wingdale 40%～60%, industrial residue 20%～40%, gypsum 3%～8%, admixture 5%～12%.
The preparation method of above-mentioned a kind of hydraulic cementing materials is characterized in that it comprises the steps:
1) by the shared mass percent of each raw material is: Wingdale 35%～75%, industrial residue 5%～50%, gypsum 0%～10%, admixture 0%～20%, the shared mass percent of gypsum and admixture is not 0 simultaneously, and the shared mass percent sum of each raw material is 100%, chooses Wingdale, industrial residue, gypsum and admixture raw material, and is standby;
2) adopt one of following two kinds of methods preparation hydraulic cementing materials:
1. with Wingdale, industrial residue, gypsum, admixture respectively grinding to specific surface area greater than 280m 2/ kg (best 350m 2/ kg～550m 2/ kg) the back remix is even, gets hydraulic cementing materials;
2. Wingdale, industrial residue, gypsum and admixture are mixed, grinding to specific surface area greater than 280m 2/ kg (best 350m 2/ kg～550m 2/ kg) after, hydraulic cementing materials.
The present invention mixes Wingdale according to the above ratio with industrial residue, and after allocating above-mentioned certain alkali-activator, sulphate activation agent into, can allow Wingdale and industrial residue produce chemical reaction.Experiment shows that the limestone particle surface in its mixture has formed a large amount of acicular calcium aluminate of hydrated carbon mineral, and makes its mixture possess the hydraulicity, has produced higher intensity.With its hydraulic cementing materials of making, time of coagulation is normal, and stability is qualified, the water retention height, and existing certain early strength has quite high later strength again, and every physical and mechanical property meets the national standard of GB/T 3183-2003 masonry cement fully.Be adapted to prepare the building mortar in the construction work.
The invention has the beneficial effects as follows: can utilize Wingdale in a large number, it has characteristics such as intensity height, workability be good, easy to use; Technology is simple; Main raw material is Wingdale and industrial residue, does not need calcining (less energy consumption), and cost is low; not only can avoid discharging great amount of carbon dioxide, use industrial residue in a large number, turn waste into wealth; also be of value to energy-saving and cost-reducing and environment protection, and significantly reduce the cost of buildings.
