Description
[01] The invention relates to the field of road engineering, in particular to a curing agent for titanium gypsum road, a preparation method and an application method thereof.
[02] Titanium gypsum is mainly industrial waste produced by adding lime to neutralize acid wastewater when titanium dioxide production enterprises adopt sulfuric acid method to produce titanium dioxide. The main ingredient is calcium sulfate dihydrate. Titanium gypsum is grayish-brown when it comes out of the waste slag treatment plant. After being left in the air for a period of time, it turns red (the ferrous ions are gradually oxidized to ferric ions), so it is also called red gypsum. Titanium gypsum has high water content, many impurities, high viscosity, and weak acidity. Compared with natural gypsum, titanium gypsum has a higher iron content. Therefore, titanium gypsum has the characteristics of high viscosity and easy to turn red when placed in the air. This makes the treatment of titanium gypsum difficult. According to relevant statistics, each production of 1 ton of titanium dioxide output about 3-6 tons of waste titanium gypsum. At present, the annual emission of titanium gypsum has reached 22 million tons, but its comprehensive utilization rate is only about 10%. It can be seen that the output of titanium gypsum causes a large amount of stacking, takes up a lot of land, wastes resources, and is particularly easy to cause environmental damage. Therefore, it is urgent to reduce the stacking of titanium gypsum and realize the multi-directional, multi-channel, and large-scale research and utilization of titanium gypsum.
[03] In addition, in most road construction, the contradiction of the shortage of natural materials is becoming more and more intense, and all of them are facing the problem of financial shortage. Therefore, on the one hand, it can guarantee the quality of road construction; on the other hand, it can alleviate the shortage of natural materials and reduce construction costs, these two aspects are worthy of consideration for road construction companies. Coupled with the implementation of the development concept of "Clear waters and green mountains are as good as mountains of gold and silver", reducing the stacking amount of titanium gypsum, increasing the utilization rate of titanium gypsum, and protecting the environment are also urgent needs of relevant government departments. If the titanium gypsum can be recycled and used as the base material in the road pavement structure, it can reduce costs, save resources, and reduce local environmental pollution. Therefore, the use of titanium gypsum as a base material in road construction can not only alleviate the contradiction of the shortage of natural materials, but also help solve the problem of titanium gypsum disposal, which has far-reaching social and environmental protection significance.
[04] Shrinkage cracking is common in the existing traditional semi-rigid base layer.
The shrinkage and cracking of the base layer can be reflected to the surface layer, causing road cracks, inconvenience to driving, and waste of resources. Although many scholars and experts have added a small amount of titanium gypsum to the water-stable base layer to compensate for shrinkage and cracking, the small amount of titanium gypsum cannot effectively alleviate the current problem of large amounts of titanium gypsum, and if a large amount of titanium gypsum is added in the water-stable base layer, there is a problem that cannot be ignored is the problem of expansion. Therefore, providing a curing agent to cure titanium gypsum as a pavement subbase filling is a problem worth studying.
[05] Preferred embodiments of the present invention seek to provide a curing agent for titanium gypsum road, a preparation method and an application method thereof in view of the above-mentioned existing problems.
[06] Preferred embodiments of the present invention further seek to provide a preparation method of the above curing agent.
[07] Preferred embodiments of the present invention further seek to provide an application method of the above curing agent.
[08] One aspect of the present invention is provided in the following manner.
[09] A curing agent for titanium gypsum road is characterized by being made of the following raw materials in percentage by weight: 90-95% of stabilizer, and 5-10% of regulator; The stabilizer is industrial slag, and the mass fraction of the main components of the slag is: 39.4% of CaO, 13.5% of Al203, 26.4% of SiO 2 , 7.5% of MgO, 0.406% of Fe203, and 1.28% of SO3 ; the regulator is sodium silicate, triethanolamine or a mixture of the two; when the regulator is a mixed reagent of triethanolamine and sodium silicate, the mass ratio of triethanolamine to sodium silicate is 1:1-3.
[10] The best mass ratio of the raw material in the curing agent is: 94% of stabilizer, and 6% of regulator; The regulator is a basic compound in the prior art, but in order to achieve the best technical effect, it is preferably a mixed reagent of triethanolamine and sodium silicate, and the best mass ratio of triethanolamine to sodium silicate is 1:2.
[11] The preparation method includes the following steps: (1) Taking the stabilizer (industrial slag) according to the proportion, drying at -80°C, and grinding to make the specific area of 400-500kg/m 2; (2) Taking the regulator (sodium silicate, triethanolamine, etc.) according to the proportion, adding to the stabilizer in step (1), and mixing thoroughly to obtain the finished curing agent.
[12] In the curing agent for titanium gypsum road of the present invention, the main mechanism is that under the action of the regulator, it can provide an alkaline environment for the stabilizer, and stimulate the hydration activity and pozzolan activity of the active material, the Si-O bond and the Al-O bond in the stabilizer are immediately broken, quickly participate in the hydration reaction, and mix with some oxides in the titanium gypsum to produce hydration products such as calcium silicate hydrate (C-S-H), calcium aluminate hydrate (C-A-H), calcium aluminate ferrite hydrate (C-A-F-H), calcium aluminosilicate hydrate (C-A-S-H), calcium hydroxide (Ca(OH)2), ettringite, etc., with the formation of these gelling substances such as C-S-H, C-A-S-H, C-A-F-H, etc., they can produce coating and adsorption effects on titanium gypsum, thereby achieving solidification of titanium gypsum and improving the strength of the base layer of titanium gypsum. In addition, when selecting the mixed reagent of sodium silicate and triethanolamine as the optimal regulator, on the one hand, triethanolamine can accelerate the early hydration reaction and improve the early strength; on the other hand, sodium silicate can effectively prevent the swelling caused by the formation of Ca(OH)2 from CaO and the swelling caused by the formation of ettringite, due to the reaction between sodium silicate and calcium sulfate, Ca(OH)2 can both generate calcium silicate (C-S-H) gel, which not only inhibits the expansion of CaO and the formation of ettringite, but also the gel material produced can play the role of curing titanium gypsum. It can be seen from the above that the invention of the curing agent for titanium gypsum road provides a good method for titanium gypsum as a subbase filling material, which can ensure the long-term performance of the road base and solve the problem of environmental pollution.
[13] During the laying of the titanium gypsum base layer, the curing agent in present invention can be mixed into the titanium gypsum according to a certain mass ratio, and the base layer can be laid after the titanium gypsum is evenly mixed. The laying process of the titanium gypsum base layer is the same as the laying process of the base layer in the prior art.
[14] During construction, the mixing ratio of curing agent and titanium gypsum is %~15% (mass percentage).
[15] The moisture content of the titanium gypsum base layer is preferably 2% below the optimum moisture content of the titanium gypsum.
[16] According to "Highway Geotechnical Test Regulations" (JTG E40-2007) compaction test T0131-2007, the optimal moisture content of titanium gypsum is determined.
[17] Compared with the prior art, the curing agent for titanium gypsum road, its preparation method and application method of the present invention have the following advantages: (1) The raw material used in the curing agent for titanium gypsum road of the present invention is industrial residue. The active substance in the stabilizer is mainly activated by the regulator to realize the curing of the titanium gypsum, and the titanium gypsum is used in the filling of the highway pavement subbase, the waste is turned into treasure and the utilization value of the titanium gypsum is improved; (2) The preparation method of the curing agent is simple, and the construction operation is easy; (3) The application method of the curing agent can be widely used in areas lacking landfills and areas with high yield of titanium gypsum solid waste, which can reduce the large amount of titanium gypsum stacking, reduce the damage of titanium gypsum to the environment, and reduce the cost of construction.
