The Introduction of white cement

Australian alumina ban disrupts Rusal production -- Australia's ban on exports of alumina and aluminium ore to Russia, including bauxite, will further disrupt supply chains and production at leading aluminium producer Rusal.

The Australian government announced the ban on Sunday as part of its ongoing sanctions against Moscow for its aggression in Ukraine, saying Russia relies on it to meet one-fifth of its alumina needs. WoodMac senior manager Uday Patel said in a statement that the ban would make it difficult for Rusal to maintain normal primary aluminum production.

Rusal said it was assessing the impact of Australia's move and would make further announcements if necessary. "It is increasingly likely that UC Rusal's only option for alumina procurement will be through a Chinese entity." The Australian alumina ban has also had an impact on white cement prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.

What is white cement?

The raw material of appropriate composition is burned to partially melted. The clinker with calcium silicate as the main component and low iron content is added with appropriate amount of gypsum, and it is a white hydraulic cementing material made by grinding, called white silicate cement (referred to as white cement).

When grinding cement, it is allowed to add limestone not exceeding 5% of the cement weight.

Note: It is allowed to add grinding aids that do not damage the cement performance to grind cement, and the addition amount does not exceed 1% of the cement weight. Incorporation of other admixtures must be tested and submitted to the Ministry of Building Materials Industry for approval.


Grade of white cement:

(1) Label: There are four labels: 325, 425, 525, and 625.

(2) Whiteness: the minimum whiteness is not less than 87. 90 whiteness and 92 whiteness. 


Characteristic of white cement: 

White cement, white Portland cement is abbreviated as white cement, is a hydraulic cementitious material made of white Portland cement clinker added to gypsum and ground. The typical feature is high whiteness and bright color.


Applications of white cement:

The typical characteristic of white cement is that it has high whiteness and bright color. It is generally used as a variety of building decoration materials. Typical examples are stucco, sculpture, ground, terrazzo products, etc. White cement can also be used to make white and colored concrete components. It is the largest variety of decorative cement produced.

U.S. oil prices surged about 10% to $105.14 a barrel. This is the highest level since 2014. The world benchmark Brent stock futures oil price soared by about 8% to $105.40 per barrel. The most direct rise in crude oil is inflation. The rise in oil prices means that people's food, clothing, housing, production costs, and living costs will rise. The direct impact is the price of goods. Rising purchasing power declines, and the currency depreciates.
Affected by the rise in global oil prices, the price of the white cement also fluctuates. If you want to know the white cement, please feel free to contact us.
