Description
Technical field
The invention belongs to building material technical field, especially relating to a kind of take flyash as gelling material of raw material and preparation method thereof.
Background technology
Construction work needs a large amount of gelling material, and what wherein consumption was maximum is all kinds of cement.A large amount of energy and the Nonrenewable resources such as Wingdale, clay to be consumed in the production of cement, discharge a large amount of greenhouse gases contaminate environment simultaneously.Utilize trade waste for main raw material, exploitation energy consumption and depletion of non-renewable resources few, little to environmental influence, can to substitute or the gelling material of Some substitute cement has important economy, resources and environment conservation value.Flyash is the solid waste given off primarily of fuel-burning power plant, in recent years power plant's dry method flyash of discharging greatly by building and building material industry utilize, but still there is the flyash of a large amount 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, can not directly be applied in cement and concrete in large quantities, are therefore failed by storing up for a long time effectively to utilize.These flyash store up land occupation, pollute surrounding environment, urgently dispose.Utilize flyash to prepare gelling material for main raw material, can Nonrenewable resources be saved, and energy-saving and environmental protection.But existing coal ash for manufacturing for the technology of gelling material exist flyash consumption few, quality of fly ash required to height and the poor problem of product performance.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, providing a kind of take flyash as gelling material of raw material and preparation method thereof, this gelling material can rapid solidification, longterm strength high.
The present invention is by the following technical solutions:
Take flyash as a gelling material for raw material, comprise 92 ~ 95 parts, the grog of parts by weight, 5 ~ 8 parts, gypsum and retardant 0.2 ~ 1.5 part; The raw material of described grog comprises 62 ~ 78 parts, the flyash of parts by weight, 22 ~ 38 parts, lime, exciting agent 0.5 ~ 2 part and 150 ~ 250 parts, water.
As preferably, described exciting agent is alkali metal hydroxide or alkaline carbonate.
As preferably, described gypsum is at least one in dihydrate gypsum, semi-hydrated gypsum, dehydrated gyp-.
As preferably, described retardant is at least one in sodium phosphate, trisodium phosphate, tripoly phosphate sodium STPP, Sunmorl N 60S.
Gelling material 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 gelling material of raw material, comprises the following steps:
The first step: take each raw material, by flyash, lime, exciting agent mixing, grinding to a 80 μm square hole sieve tails over and is less than 5%, obtains admixtion;
Second step: described admixtion is mixed with water, stirs, obtain charge pulp;
3rd step: by described charge pulp at 90 ~ 98 DEG C of Water Under thermal treatment 8 ~ 16h, obtain Hydrothermal Synthesis slip;
4th step: described Hydrothermal Synthesis slip pressure filter is dewatered, obtains Hydrothermal Synthesis material block;
5th step: after described Hydrothermal Synthesis material block is calcined 30 ~ 120min under 750 ~ 950 DEG C of conditions, blow air cooling and obtain grog;
6th step: get 92 ~ 95 parts, grog and mix with 5 ~ 8 parts, gypsum, retardant 0.2 ~ 1.5 part, grinding to a 80 μm square hole sieve tails over and is less than 4%, obtains gelling material.
The hydrothermal treatment consists of the 3rd step is carried out in hydro-thermal reaction tank.
The obtained material block of flyash, lime, exciting agent and water or pellet are obtained grog by the present invention after hydrothermal treatment consists and calcining, then grog, gypsum and retardant are mixed and made into gelling material.Its principle 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), 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.
In the present invention, exciting agent 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 inorganic coagulation material mesosilicic acid dicalcium and seven aluminium ten dicalcium, improve the gelling of gelling material.
In the present invention, gypsum can react with seven aluminium ten dicalcium and water and form the very high calcium trisulphoaluminate hydrate of gelling, and 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 gelling material and impact construction.
The invention has the beneficial effects as follows:
(1) calcination process of gelling material grog of the present invention not only can the rigid Dicalcium Phosphate (Feed Grade) of synthetic water and seven aluminium ten dicalcium, and can residual carbon in burn off flyash, therefore can be raw material with the low-quality flyash that carbon content is high, as the flyash etc. of wet method discharge, utilization of fly ash rate is large, can also reduce the pollution of flyash to environment;
(2) the present invention adopts the reaction in exciting agent acceleration hydrothermal treatment process slip between each component, promotes the acceleration of reaction and thoroughly completes, reducing hydrothermal treatment consists hear rate, thus shortening hydrothermal conditions, raising productivity effect and equipment use efficiency;
(3) preparation method of gelling material of the present invention is simple, low for equipment requirements, and low without the need to large-scale equipment, calcining temperature, greenhouse gas emissions are few;
(4) gelling material of the present invention has quick setting and rapid hardening, characteristic that high, the resistance to vitriol aggressiveness of longterm strength is good, be specially adapted to tunnel, under water, saline and alkaline area and coastland engineering.
