And the process of cement is melting?

No, melting is a phase transformation process that heats a substance from a solid state to a liquid state, and the cement results in a suspension.

It is only mixed with cement, not dissolved, nor melted, melting is the solid-liquid transformation process, and dissolution is mixed evenly and forming a molecular state.

It is a hydration process, not a melting process.

It's hydration. A physicochemical process.

Cement is a kind of hydraulic cementitious material, that is, a finely ground inorganic material, which is mixed with water to form a cement slurry, which undergoes coagulation and hardening through the hydration process, and can maintain strength and stability even in water after hardening.

Cement should be able to be made into concrete or mortar that can maintain sufficient working hours and reach the required strength level after a certain period of time, and must also have long-term volumetric stability.

The hydraulic hardness of cement is mainly due to the hydration reaction of calcium silicate, but other chemical compounds, such as aluminate, can also be involved in the hardening process. The sum of the ratios of active CaO and SiO2 in cement should be at least 50 by weight.

Cement is made up of individual small particles of different component materials, but these component materials should be statistically homogeneous in their chemical composition. A high degree of homogeneity of all the properties of cement must be achieved by a continuous high-flow production process, in particular by a suitable grinding and homogenization process.

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. After the chemical reaction, chloride salt can be obtained, which can quickly loosen the air-dried cement.

Generally speaking, Portland cement cannot be melted, and it is not known which kind of cement you use in your household.

I'm going to buy a pulverized cement pole to know who has it.

Dear, what is able to quickly dissolve the already solidified cement. 1. We need to understand the chemical properties of cement, cement contains alkaline components such as calcium hydroxide, if you want to dissolve it, you need to use substances containing acidic components to take the shed to have a chemical reaction with it, we can use liquids such as hydrofluoric acid or hydrochloric acid to dissolve Hu or cement. 2. Now there is a cement dissolving agent on the market that can quickly and effectively dissolve cement, which is made according to the chemical properties of cement, containing acidic components, and chemical reactions will occur when the two meet together.

There is no chemical reaction.

1. When the cement is mixed with an appropriate amount of water, it begins to form a plastic slurry with machinability. Over time, the slurry gradually loses its plasticity and becomes a tight state that cannot flow, after which the strength of the slurry gradually increases until it finally becomes a stony solid with considerable strength.

2. The coagulation and hardening of cement is a complex physico-chemical process, and the fundamental reason lies in the characteristics of the mineral components that make up cement clinker. Cement clinker minerals will undergo hydrolysis or hydration reaction when exposed to water and become hydrates, which are overlapped and connected with each other by a variety of gravitational forces in a certain way to form the structure of cement stone, resulting in strength.

There is no reaction, and when it crystallizes, it becomes a "stone".
