The Introduction of white cement

Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of production capacity. In the context of scientific carbon reduction, coal consumption will continue to dominate for a long time, and the scarcity of new batches of production capacity will drive up asset prices. The core increase in demand is provided by traditional energy sources, driving oil and natural gas prices to continue to rise, and overseas coal prices hitting new highs. The rise in coal prices will also drive up the price of white cement.

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.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the white cement would keep being influenced by the high energy prices.
