Hydrogen Peroxide Cement Reaction
On the Reaction of Hydrogen Peroxide to Cement
In recent times, the technique of chemistry has gradually refined, and the reaction of various materials has been explored more and more deeply. Among them, the reaction of hydrogen peroxide with cement is quite important in the academic world.
Hydrogen peroxide, the molecular formula is\ (H_ {2} O_ {2}\), is oxidizing. Cement is a commonly used material in construction, and its composition is complex. It contains calcium silicate and calcium aluminate.
When hydrogen peroxide meets cement, the two react. Hydrogen peroxide decomposes and releases oxygen. This oxygen may cause many changes in the cement system. In the microscopic environment, the formation of oxygen bubbles can affect the structure of cement slurry. At first, the slurry is still in a flowing state, and the addition of oxygen bubbles makes the slurry volume slightly increase, and its rheological properties also change.
And the decomposition of hydrogen peroxide may affect the process of cement hydration. Cement hydration is the foundation of its setting and hardening. The products produced by the decomposition of hydrogen peroxide may interact with cement hydration products. Such as calcium hydroxide, which is a common product of cement hydration, may react with the residue after the decomposition of hydrogen peroxide to change the composition and morphology of hydration products.
Furthermore, from a macroscopic perspective, this reaction also affects the performance of cement products. In terms of strength, if the reaction is moderate and the oxygen bubbles are evenly distributed, an appropriate amount of pores can be introduced into the product, or its heat insulation and sound absorption properties can be beneficial. However, if the reaction is too severe, the pores are large and disordered, and the strength of the product will be damaged. In terms of durability, the change in the reaction may affect the ability of the cement product to resist external erosion.
To make good use of this reaction, its mechanism must be studied in detail. Control the amount of hydrogen peroxide, the temperature and humidity of the environment and other conditions, so that the reaction can proceed according to people's wishes. In this way, it can be used in construction techniques, new ways can be added, and high-quality materials can be created to meet the needs of construction in this world.
