Global concrete foaming agent market trend 2023-2028 How to mix cement materials in foam concrete construction? by Newsdesignerstudiostore

The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on concrete foaming agent.

Cement is the main raw material of foam concrete. Because foamed concrete is mostly cured at room temperature and mixed with a large amount of foam, these two points determine its high cement proportion.

 

This is the fundamental difference between it and aerated concrete. Due to the use of autoclave, aerated concrete mainly depends on the hydration reaction of fly ash and lime under high heat and high pressure to produce gelling, and cement is auxiliary.

 

When foam concrete is produced at room temperature, active micro-aggregate will not produce hydration reaction quickly, and its foam still depends on the cementation of cement. Therefore, the mix proportion of foam concrete should be cement as the main body and high cement proportion should be adopted.

 

In general, the amount of cement should account for 50% of the total dry material. 50% should be the minimum limit for curing at room temperature. When pouring on site, the proportion of cement should account for more than 80% of the total dry material. The density of foamed concrete at room temperature is less than 600kg/m3, and the proportion of cement can not be less than 70% of the total material. When the density is less than 400kg/m3, the proportion at room temperature should account for more than 90% of the total dry material.

 

In the design of cement proportion, the following factors should be considered:

 

1. The variety of cement. The cement varieties with high early and late strength (such as double fast Portland cement) can appropriately reduce the proportion, while the cement varieties with low late strength or low early strength should increase the cement proportion.

 

2. The strength grade of cement. The proportion of high strength grade cement can be reduced, while that of low strength grade cement should be increased.

 

3. The quality of cement. The proportion of the cement of the new dry rotary kiln in the large factory can be reduced appropriately, while the cement in the shaft kiln of the small factory or the cement with a large amount of admixture should be properly increased.

 

4. The density and strength requirements of foam concrete. The proportion of cement with low density or high strength requirement should be increased, while that with high density or low strength requirement can be reduced.

Due to the Russia-Ukraine conflict and the covid-19 pandemic, how will the international situation develop is highly uncertain. It is too difficult to assess its economic impact properly. However, we could see energy prices and commodity prices keep rising and supply chains are disrupted. Therefore, concrete foaming agent prices are expected to rise in the future.
