Abstract
A method of cementitious material being prepared using barium hydroxide and silicic acid, barium hydroxide and silicic acid are dissolved in deionized water respectively according to molar ratio 1:1, are then mixed in a sealed container, water bath with thermostatic control, is filtered, it is dry to get aquation barium silicate cementitious material.Barium silicate cement early strength is high, and has biggish density.It can be configured to uniformity and the preferable loaded concrete of density with it, it also has than great other than the physical property with normal concrete.It can be used to protect the radioactive radiation combined with high temperature or sulphate corrosion for organism, it is also possible to rudimentary radioactive waste in its long-term storage.The present invention is alternative to be fired to obtain clinker using barite and clay, and the method that suitable gypsum intergrinding forms barium silicate cement is added, does not need to calcine using sol-gal process, more have an economic benefit.
Description
Technical field
The invention belongs to field of cementing material technology, in particular to a kind of to prepare cementitious material using barium hydroxide and silicic acid
Method.
Background technique
With the development of chemical engineering industry and production, the Barium Residue and barium slag yield increase year by year.Since the Barium Residue has
Certain toxicity, can cause very big pollution to environment, be handled both at home and abroad it also very prudent.The Barium Residue serves not only as
Mineralizer can improve strength of cement to a certain extent, improve cement performance, and may further be used to preparation aquation barium silicate cement,
With early strength, high, biggish density, can be configured to uniformity and the preferable loaded concrete of density.To control cost,
It economizes on resources, energy-conserving profit waste has obtained certain application in construction material.Therefore, the Barium Residue application is furtherd investigate, to building
The development for building material has positive meaning.Barium cement belongs to the special cement with low hydration heat, can be used as the weight of radiation protection
Spar concrete.
Summary of the invention
In order to overcome the disadvantages of the above prior art, barium hydroxide and silicic acid are used the purpose of the present invention is to provide a kind of
The method for preparing cementitious material, using barium hydroxide and silicic acid as raw material, using deionized water as solution, preparation is mixed and stirred has anti-spoke
Penetrate the barium silicate cementitious material of characteristic.This method tool environmental suitability is strong, and energy conservation and environmental protection, resource recycling utilizes, easy to control,
The advantages of convenient for industrial applications
To achieve the goals above, the technical solution adopted by the present invention is that:
A method of cementitious material being prepared using barium hydroxide and silicic acid, barium hydroxide and silicic acid are rubbed according to Ba:Si
You are dissolved in deionized water the ratio than 1:1 respectively, are then mixed in a sealed container, water bath with thermostatic control, filter, dry,
Up to aquation barium silicate cementitious material.
Preferably, the mass ratio of the deionized water and barium hydroxide is (1.5-3): 1.
Preferably, the mixing carries out under normal temperature environment, rear sealing and standing is sufficiently stirred 1 hour.
Preferably, before the sealing and standing, nitrogen is poured into sealing container.
Preferably, the water bath with thermostatic control condition is 60 DEG C, 24 hours.
Preferably, the mixed solution of the water bath with thermostatic control is introduced into Buchner funnel, low pressure filter, successively with deionized water,
Dehydrated alcohol successively filters 2 times.
Preferably, the filtered product is placed in a vacuum drying oven at 60 DEG C dry.
Preferably, the chemical component of the barium hydroxide and silicic acid is as follows:
Barium hydroxide: analysis mode Ba (OH)2·8H2O, Ba (OH)2·8H2O content >=98%, barium impurity content≤1%；
Silicic acid: impure highest content: nonvolatile matter 0.20%, calcination loss 20-28%, chloride 0.005%, sulfate
0.02%, iron 0.005%, in terms of Pb, heavy metal 0.005%.
The present invention, which prepares gained cementitious material, can be used for putting for organism protection with what high temperature or sulphate corrosion combined
The radiation of penetrating property, or for radioactive waste rudimentary in storing for a long time.
Barium silicate cement early strength is high, and has biggish density.Uniformity can be configured to it and density is preferable
Loaded concrete, it other than the physical property with normal concrete, also have than great.It can be used to protect for organism
With the radioactive radiation that high temperature or sulphate corrosion combine, it is also possible to rudimentary radioactive waste in its long-term storage.This hair
Bright alternative use barite and clay are fired to obtain clinker, and the side that suitable gypsum intergrinding forms barium silicate cement is added
Method is not needed to calcine, more be had an economic benefit using sol-gal process.
Detailed description of the invention
Fig. 1 is process flow chart of the invention.
Fig. 2 is the XRD diffraction pattern of present invention test products therefrom.
Specific embodiment
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of method using barium hydroxide and silicic acid preparation cementitious material, steps are as follows:
(1) 157.735g barium hydroxide is weighed, is placed in deionized water, dissolution is sufficiently stirred with glass bar；Barium hydroxide
Chemical component is as follows: analysis mode Ba (OH)2·8H2O, Ba (OH)2·8H2O content >=98%, barium impurity content≤1%；
(2) according to Ba:Si molar ratio 1:1, silicic acid 39.05g is weighed, is placed in deionized water, is sufficiently stirred with glass bar
Dissolution；Deionized water 300g is used in two steps altogether.The chemical component of silicic acid is as follows: impure highest content: nonvolatile matter
0.20%, calcination loss 20-28%, chloride 0.005%, sulfate 0.02%, iron 0.005%, in terms of Pb, heavy metal
0.005%；
(3) step (1) is mixed with two kinds of solution that (2) configure, is mixed in 500mL sealing container, or stir
It is placed in sealing container again after mixing uniformly, sealing and standing 1 hour under normal temperature environment.
(4) mixed solution in step (3) is poured into nitrogen and sealed, or pour nitrogen before standing, then will
Container after sealing is placed in constant temperature water box, and temperature is set as 60 DEG C, heating water bath 24 hours；
