Abstract
The invention discloses a binding material coal ash-cement and a production method thereof. The binding material coal ash-cement is prepared from 0-95 percent by weight of coal ash binding material, 0-95 percent by weight of active admixture, 0-5 percent by weight of alkaline exciting agent, 0-10 percent by weight of lime, 0-1 percent by weight of water reducing agent and 0-1 percent by weight of early strength agent. The production method comprises the steps of: weighing all raw materials according to a preset proportion, then uniformly mixing the raw materials, and packaging to obtain the binding material coal ash-cement. Grade 12.5, grade 17.5, grade 22.5, grade 32.5 and grade 42.5 of binding material coal ash-cement are obtained according to different proportions of the components, and can be used for constructing plaster cement, cement plaster, thermal mortar, underground engineering and the like.
Description
Technical field
The present invention relates to a kind of high-strength environmental protection gelling material, specifically, relate to a kind of as the flyash-cement of building the cement of wiping one's face, sand-cement slurry, thermal insulation mortar by laying bricks or stones.
Technical background
Flyash is as large industrial residue, and its processing and comprehensive utilization have been accompanied and paid close attention to by countries in the world.In China's method commonly used is blended material and concrete adulterant, brick, the building block that original state flyash or fine-ground fly-ash are made cement.Flyash is as the blended material and the concrete adulterant of cement, and China standardizes, and has formulated the corresponding techniques standard.But use the dried row's top grade ash, the one-level that are preferably sorting grey at present, the utilization ratio of a large amount of wet ash discharges and inferior grade ash is also lower.Exciting with the method for Study of Activation of flyash is more, mainly is that mechanical grinding method, lime alkali excite method, steam-cured method.At present, use more complex excitation, promptly lime, gypsum, sodium sulfate mix dry grinding with flyash; Though early strength increases, activity is not high, and volume is low; Be not higher than 30%, effect is undesirable, poor stability; Often to join miserable slag etc., add lime alkali high temperature and excite with steam-cured and excite, fail to be used widely because cost is high, investment is big, complex process.
Summary of the invention
The object of the present invention is to provide a kind of production energy consumption low, cost is low, the gelling material flyash-cement of water-tolerant.
The objective of the invention is to realize through following proposal: it is processed by fly ash gel material, active admixture, alkali-activator, lime, water reducer and hardening accelerator; The weight proportion of each component is: fly ash gel material 0%～95%; Activity is closed material 0%～95%, alkali-activator 0%～5%, lime 0%～10% disastrously; Water reducer 0%～1%, hardening accelerator 0%～1%;
Said fly ash gel material is flyash, gypsum and cement three's mixing, and three's weight proportion is a flyash: (gypsum+cement)=0%～100%: 100%～0%;
Described flyash is one-level, the second class powered coal ash of power plant, or the wet ash discharge of levigated and low waits greyly, and gypsum is natural dihydrate gypsum or desulfurated plaster or anhydrite, and powder size 60 orders～500 orders, cement are cement clinker or various label cement;
Said active admixture is one or more mixtures in levigate blast furnace slag, ground steel slag, the levigate Fluorspar Powder;
Said alkali-activator is for being selected from Na
