Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. The cement proportion problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement ratio. This will cause the concrete to harden too quickly, and lead to cracking.

2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in the future. Concrete Surface Watering You can water the surface of the concrete often to speed up the drying process. Concrete will shrink if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation rates of the concrete are accelerated. This results in cracks on the concrete's surface. Concrete constructions are most likely to crack in the winter or summer because of the temperature difference.

Solution: Add an agent to prevent cracking. A variety of inorganic composite materials can prevent over 80% of the foam cement from cracking. Add 2-3 kilograms of anti-cracking material per cubic meter.

Overview of Aluminum Diboride AlB2 Powder

Aluminum boride (AlB2) is a binary compound formed from aluminum and boron. It is a red solid under normal temperature and pressure. It loses surface gloss when heated. Stable in cold dilute acid, decomposed in hot hydrochloric acid and nitric acid.

Aluminum boride (AlB2) is one of two compounds of aluminum and boron, the other being AlB12, commonly known as aluminum boride. AlB12 is a black glossy monoclinic crystal with a specific gravity of 2.55 (18°C). It does not dissolve water. The AlB2 single crystal is parallel to the hexagon of the substrate.

The structure of aluminum diboride (AlB2) is similar to that of graphite flakes. There is an Al atom between the B atom and the B atom, which is very similar to the structure of magnesium diboride. AlB2 single crystals exhibit metallic conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminum boride is considered a hazardous substance because it reacts with acids and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid to liberate borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are various structural types in the AlB2 structural family.

Application of Aluminum Diboride AlB2 Powder

Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride with an absolute temperature just above 40K (equivalent to -233°C) becomes a superconductor. Its actual working temperature is 20 ~ 30K. To achieve this temperature, we can use liquid neon, liquid or closed cycle refrigerators to accomplish cooling. These methods are simpler and more economical than the current industrial use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium diboride retains superconductivity as good or better than niobium alloys in a magnetic field, or with an electric current flowing through it.

In a recent interview with Izvestia, Russian Federation Council Chairman Matviyenko said that Russia is open to dialogue with the West based on mutual respect, but the opportunity to resume dialogue will only come after the end of special military operations.  

Matviyenko also noted that Europe currently lacks politicians who can make independent decisions.  She said the EU's strategy to wean itself off Russian energy by 2027 would be costly, with Russia supplying 40 percent of Europe's gas, 27 percent of its oil, and 46 percent of its coal, and was essentially "anti-European" and a "tax" on US global dominance.

On Sweden's and Finland's plans to join NATO, Matviyenko said Russia will take corresponding measures if NATO weapons and equipment appear in the two countries, and Russia is capable of guaranteeing its own security. 

Besides, speaking by video at an international conference, Ukraine's minister of agricultural policy and Food, said the country's grain iron powder are expected to continue to be influenced by international situations.

What is Zinc Sulfide

Description of Zinc Sulfide :

Zinc sulfide chemical formula is ZnS, and the molecular weight is 134.72. It is formed by interacting with zinc ions (Zn2+) and sulfur ions (S2-) through ionic bonds. The zinc ion is located in the center of a regular tetrahedron formed by four sulfur ions in the crystal structure. In contrast, the sulfur ion is located in the center of a tetrahedron. This structure can be described as a face-centered cubic crystal system in which zinc and sulfur ions occupy the vertex and face-centered positions of the lattice, respectively.

Zinc Sulfide is an insoluble white solid that is insoluble in water but is soluble in bases and acids. Its density is 3.98 grams per cubic centimeter with a melting temperature of 1350 degrees C and an optimum boiling temperature of 1650 degrees C. Zinc sulfide has high hardness and good optical transparency, and its light transmission range is 200-400nm. The chemical properties of zinc sulfide are relatively stable, but it can also react under certain conditions.

3. solvothermal method

The solvothermal method is a new method for preparing zinc sulfide. The method dissolves zinc salt and sulfur salt in organic solvent under high temperature and high pressure and generates zinc sulfide powder through hydrothermal reaction:

Preparation solution: Dissolve the appropriate amount of zinc and sulfur salt in the organic solvent to make a solution.

High temperature and high-pressure reaction: The above solution is placed in a high-temperature and high-pressure reactor, and the hydrothermal reaction is carried out under high temperature and high-pressure conditions to produce zinc sulfide powder.

Collection: The generated zinc sulfide powder is collected and treated accordingly.

The solvothermal method has the advantages of high product purity, good crystallinity, and a relatively simple process. In addition, the method can use different organic solvents and reaction conditions to regulate the product properties. However, this method requires high-temperature and pressure equipment, and the recovery and disposal of organic solvents require a certain cost and technology.

In short, different production methods of zinc sulfide have advantages and disadvantages, and the selection of appropriate production methods needs to be comprehensively considered according to the actual needs and conditions.
