The water-reducing agent should be used with concrete admixture, which will reflect the water reduction effect. Cement quality is therefore a direct factor of the effect of water-reducing agent. When dealing with different types of "problem" cements,…
In the UK, more than 100 schools were closed because of the danger of collapse In the UK, many schools use RAAC (autoclaved aerated cement) This is a concrete material that is lighter. In 2018, the roof of a school in southeast England fell down…
Concrete is a modern material that uses a variety of chemical additives, each with its own unique characteristics. These additives play an important part in improving the performance of the concrete and maintaining quality. Here are a few chemical ad…
What is surfactant? Surfactants belong to a group that lowers the surface tension on a liquid. They can be adsorb on interfaces such as gas-liquids or liquids-liquids. By doing so, they change the properties and affect the stability, wettability of t…
As a typical material with two dimensions, graphene is widely used and highly sought-after by the scientific and industrial community. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale (1 to 100 nm) materia…
Boron has been a major name in the world of chemistry. There have been two Nobel Prizes in Chemistry for the work done on boron. There are a few heat-resistant products on the market that have boric acid added to the glass. This means the glass wi…
What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a weight of 2318.5. It is a form of tungsticanhydride. Tungsten dioxide is not produced in industrial production. The tungsten-trioxide salts are classified according to thei…
The titanium hydride used as a getter is also used to make metal foams, as well as to provide high-purity hydrogen. It can also be found in powder metallurgy and metal-ceramic sealing to supply the alloy powder with titanium. Titanium Hydride is b…
Boron carbide is also known as black Diamond. It has a molecular structure of B4C. The powder is typically grayish. It is one the three hardest materials known (the other two being diamond and cubic boronnitride). It can be found in many industrial a…
In recent years, transition metal dichalcogenide was one of the key two-dimensional quantum functional material in the world. These materials have a honeycomb like graphene but have spin-orbit coupling that allows them to exhibit novel properties. As…
GaN-based chargers have been introduced to the market. These chargers provide a high amount of power for the device, while still maintaining a size that is reasonable, and even take up less space than the traditional chargers. Gallium Nitride, or GaN…
The powder boron is available in four variants. These are hexagonal boron, rhombohedral (RBN), cube boron and wurtzite. The most common boron nitride produced is white graphite, which has a structure similar to graphite. The need to increase battery…
Mono (2,propylHeptyl), ether, is a surfactant non-ionic with wettability and defoaming qualities, as well as hard surface degreasing. What is mono(2-propylheptyl-ether)? Mono (2,propylHeptyl), ethe has a non-ionic surface tension with defoaming, w…
Hasad Foods, the agricultural investment arm of Qatar's sovereign wealth fund, said the government would increase its grain reserves from 250,000 tons to 300,000 tons in the near future, which is enough to feed the population for six months. With a…
At room temperature, transparent light yellow liquid. pH value: pH 4 - 7. Didecyl Dimethyl Ammoniumchloride: Didecyl Dimethyl Ammonium chloride is characterized by rich and fine foam, low power of degreasing, low irritation to the skin and hair, g…
