Something melts quickly, dries and is hard

Depending on what kind of rubber you have, if it's a thermoplastic elastomer, you can try to dissolve it with xylene.

If it's cross-linked rubber, then you don't want to melt or dissolve. Because cross-linked rubber forms a network structure through chemical bonds, it is unmeltable and insoluble.

After the cement is hydrated and hardened, the products formed are mainly calcium silicate gel, calcium hydroxide and calcium sulfoaluminate, which are alkaline. The use of weak acids can corrode calcium hydroxide and slowly corrode cement stone. The use of hydrofluoric acid can dissolve siliceous minerals, which can dissolve cement stone relatively thoroughly.

Cement is a powdered hydraulic inorganic cementitious material. After adding water and stirring into a slurry, it can be hardened in air or better hardened in water, and can firmly cement sand, stone and other materials together.

The mixture of early lime and pozzolana was similar to that of modern lime pozzolana cement, and the concrete made from cemented crushed stone was not only strong when hardened, but also resistant to the erosion of fresh or salt water. For a long time, as an important cementitious material, it has been widely used in civil construction, water conservancy, national defense and other projects.

With hydrochloric acid, cement is silicate and can be dissolved in hydrochloric acid. Just use dilute hydrochloric acid, not too strong, otherwise it will volatilize quickly.

Answer: "There is nothing that can quickly dissolve solidified cement in a short period of time." If it is necessary to dissolve the solidified cement, a cement dissolving agent can be used, but for a long time. Cement dissolving agent is a new type of soaking type to dissolve industrial and pipeline cement dredging products, mainly by repeatedly using the product dilution solution for a long time to soak the dredging area to achieve the effect of dissolving cement.

High temperatures are fine. The main ingredient of cement is sodium silicate, which has a high melting point!

Generally speaking, it is heating, I don't know what you want to melt the glue on the object, if it is clothes, you can try to use an iron or hair dryer! Adopt it.

Fire: When the glue is dry, burn it clean with a fire.

Prepare a basin of cold water, a basin of hot water, and repeatedly alternate between cold and hot water.

For safety reasons, it is not recommended to add material to cement. 100% cement is 28 days, it is recommended to wait patiently. If you want to go a little faster, you can increase the temperature to promote coagulation.

Principle: The solidification of cement is a chemical reaction, taking aluminate cement as an example, aluminate cement reacts with water to form calcium hexaaluminate hydrate, which plays a curing role. When the temperature increases, the calcium hexaaaluminate hydrate loses water, making the material stronger.

The best way to do this is to add Lime King, which is a low-cost and easily available material.

Thank you for the trouble to adopt!

Seems a bit of a hassle.

Limestone and concrete are slightly soluble in water, and hydrated lime is also fragile after drying and reacting with air.

It would be better for the landlord to explain the role of the request.

I don't know what kind of thing you call overwork.

Under normal circumstances, as long as you drink some tea, it can be relieved, after all, the food is dry and hard, after chewing, when it reaches the stomach, the stomach acid will naturally decompose it, drink water or tea, just moisten the stomach, will not melt it.

If you feel uncomfortable all the time, it may be that your stomach is not very good, you can sit and drink plenty of water, then rub your stomach with your hands, and rest for a while.
