Description
Technical Field
The application belongs to the field of building materials, and in particular relates to a waste glass powder low-carbon gel material and a preparation method thereof.
Background
In the cement production process, due to the calcination of raw material limestone and the use of coal, up to 8% of artificial CO can be generated 2 Is discharged and is an important raw material for preparing concrete, and the yield thereof is continuously increasing with the wide use of concrete around the world. Worldwide, since 1990, CO was caused by the massive cement usage demand 2 The emission is also increasing, and the current CO produced by the cement industry 2 The emission amount accounts for 6% -7% of the total carbon emission amount worldwide.
On the other hand, glass waste is reported to be as high as 1.3 hundred million tons per year worldwide due to the widespread use of glass products. While the properties of various glass products vary widely, most waste glass has failed to meet the requirements for glass remanufacturing, it is estimated that less than 10% of waste glass is available for glass remanufacturing and the recycling process is complex. Therefore, most waste glass is disposed of by natural landfills. However, glass is considered as a material which is hardly likely to be naturally degraded due to its good stability, and heavy metals such as copper and cadmium contained in its components cause pollution to soil and groundwater. How to dispose of large amounts of waste glass worldwide is thus a challenge now in urgent need.
The alkali-activated cementing material is an inorganic polymer synthesized by the reaction of aluminosilicate material, concentrated alkali hydroxide and alkali silicate solution, and has an amorphous three-dimensional structure. Compared with Portland Cement (PC), AAM has less carbon emissions and lower energy consumption in the manufacturing process, and exhibits better durability in corrosive environments. Besides, the AAM is widely prepared from industrial wastes such as slag and fly ash, and besides, the academic adopts agricultural wastes such as rice husk ash, bagasse ash, palm kernel oil ash, coconut husk ash and the like to prepare the AAM, so that the aim of recycling wastes can be achieved while reducing the influence of building materials production on the environment. However, the above materials must be calcined during the preparation of AAM. In contrast, it has been newly discovered in recent years that the AAM can be prepared from waste glass frit as a precursor material without this step.
The current research shows that the cementing material with excellent compressive strength can be prepared by adopting the waste glass powder and utilizing the alkali excitation mode. And the compressive strength of the waste glass powder with finer grain size, alkali solution with proper concentration and curing conditions can be effectively improved.
Typically, a cementing material and a preparation method thereof are disclosed in Chinese patent CN109231860B, wherein industrial solid waste, an additive and an excitant are added. The method adopts the combination of fly ash, slag, copper slag, glass slag and coal gangue as wastes and adopts alkali, phosphate and sulfate as exciting agents, so that solid waste treatment can be realized, and the compressive strength of the water culture 3d is not higher than 66MPa.
The waste glass powder is adopted to prepare the alkali-activated cementing material, so that a large amount of CO caused by mass production of cement can be improved 2 And due to the emission problem, a large amount of waste glass can be recycled. However, in the current research, there are very few systematic studies on compressive strength of AAGM with respect to synergistic effects of curing humidity, curing temperature and curing time. Therefore, aiming at the defects of the prior researches, the maintenance mode which can lead the waste glass powder to achieve the best compressive strength by the alkali-activated cementing material has obvious necessity.

FIG. 2 is a graph of the compressive strength results of a waste glass frit low carbon cementitious material. It can be seen from fig. 2 that the compression strength of the waste glass frit low carbon gel material is significantly improved over 50 ℃ at the curing temperature of 75 ℃ regardless of humidity and time, and the compression strength tends to increase with the increase of curing time at both temperatures. This shows that in A certain range, the alkali excitation reaction can be better promoted at A higher temperature and for A relatively longer curing time, so that more N-A-S-H gel is formed, and the mechanical properties of the waste glass powder low-carbon gel material can be better improved. And at two temperatures, the low humidity curing environment has more positive influence on the compressive strength of the waste glass powder low carbon gel material than the high humidity curing environment. This may be a low humidity environment that causes evaporation of water (adsorbed, absorbed or both) present in the waste glass frit low carbon gel material, thereby playing an important role in the later formation of microcracked and less microporous materials. And at such temperatures, high humidity may cause some hydrolysis of the gel formed in the waste glass frit low carbon gelling material.
And when the temperature is raised to an ultra-high temperature of 120 ℃, the compressive strength shows a completely opposite trend to the previous one. Compared with the curing environment at 75 ℃, the overall compressive strength at 120 ℃ is obviously reduced, and the compressive strength is reduced along with the increase of curing time. This suggests that excessive temperatures may hinder the alkali-activated reaction mechanism of the waste glass frit low carbon gel material and may even damage the internal structure of the test block, and this is more pronounced as the curing time increases. In addition, the waste glass frit low carbon gel material cured at high humidity has better compressive strength than the low humidity environment in the curing environment of 120 ℃, and a possible explanation is that the temperature is too high so that the evaporation of water in the material is too serious, and then higher humidity is needed to maintain the balance of water in the waste glass frit low carbon gel material.
In summary, it can be found that the proper temperature and humidity curing environment is matched with a certain curing time, so that the alkali excitation reaction of the waste glass powder low-carbon gel material has an obvious promotion effect. In A certain range, the compressive strength of the waste glass powder low-carbon gel material can be obviously improved along with the increase of curing temperature, and the relatively higher temperature can enable the alkali excitation reaction inside the waste glass powder low-carbon gel material to be more thorough, so that more N-A-S-H gel is generated. And a relatively low cure humidity can result in a denser, less microporous structure for the waste glass frit low carbon cementitious material. And once the temperature is too high, the internal reaction mechanism of the waste glass powder low-carbon gel material is destroyed, and the destruction condition is deepened along with the extension of the curing time. And when the temperature is too high, higher curing humidity is needed to prevent the moisture in the waste glass powder low-carbon gel material from increasing seriously. Finally, the invention is cured for 3 days under the environment of 75 ℃ and 10% humidity, and the waste glass powder low-carbon gel material with the compressive strength reaching 91.93MPa is obtained. Therefore, the waste glass powder low-carbon gel material can meet higher strength requirements. The cement can not only reduce the environmental crisis caused by cement production, but also show excellent performance after being cured for 3 days in a certain temperature and humidity environment.
