Global foamed concrete market trend 2023-2029 How to avoid deformation and cracking of foamed concrete materials by Newsmarco-berti

Russian president demanded that exports of Russian gas to "unfriendly" countries be settled in rubles. The demand has raised concerns in Germany about possible supply disruptions and the impact on industry and households if utilities do not pay in robles. Europe gets about 40% of its gas from Russia. Last year, Europe imported about 155 billion cubic meters. Germany, Europe's largest economy, depends heavily on Russian gas.

The chief executive of Germany's E.ON said the German economy would face "significant damage, which should be avoided if possible" without Russian supplies. He also said it would take Germany three years to wean itself off Russian gas.  

In the event of a supply disruption, Germany's gas network regulator would prioritize home heating over industrial use, so energy-hungry manufacturers such as steelmakers would be the first to suffer, he said.

The volatile international situations will continue to affect the markets and prices of many commodities like the foamed concrete.

Foam concrete is prone to cracking during maintenance, mainly caused by unscientific construction and maintenance of the proportioning. Luchuang has a series of solutions. In the years of construction, Luchuang has accurate material proportions for different climatic conditions and different terrains. The construction quality is industry-leading.


Aggregates rarely change during concrete hardening and use unless there is a significant volume change due to heat and cold. Chemical shrinkage, carbonization shrinkage, drying shrinkage, etc., all come from cement slurry. Foam concrete is mainly composed of cement and does not contain aggregates, determining its considerable shrinkage.

The strength development of foamed concrete is relatively slow in the initial curing stage, and its low thermal conductivity makes it difficult for the heat generated by hydration to be discharged to the outside in time, which often leads to a sharp increase in the initial temperature of foamed concrete, resulting in volume expansion. Internal thermal stress and cracks are generated.

The strength of foamed concrete is at a low level (generally not higher than 10MPa) even after it is completely hardened, so any abnormal external mechanical force will also cause its deformation or even cracking and failure. Possible technical approaches to reduce shrinkage and control cracking of foamed concrete.


Based on the above-mentioned analysis of the volume deformation phenomenon and internal causes of concrete in the process of hydration and hardening and use, and the study of the similarities and differences between foam concrete and ordinary structural concrete in terms of composition, structure, and performance, combined with foam concrete preparation and application may appear In this paper, the following possible technical approaches are proposed on how to reduce the shrinkage and control cracking of foamed concrete.


1) Use fast-hardening and low-heating cement as the cementitious material for foam concrete;

2) Add an appropriate amount of fine aggregate, and choose a reasonable mix of cement and sand;

3) Strengthen early maintenance and timely heat dissipation to reduce artificial abnormal external mechanical impact;

4) Introduce appropriate and appropriate expansion components to make up for volume shrinkage; reduce space constraints and increase free deformation components.

China's non-manufacturing purchasing managers index for March was released by the China Federation of Logistics and Purchasing and the Service Industry Survey Center of the National Bureau of Statistics today. An index of business activity for the non-manufacturing sector as a whole fell below 50 percent. 

 China's non-manufacturing business activity index was 48.4%, down 3.2 percentage points from the previous month. The new orders index was 45.7 percent, down 1.9 percentage points from the previous month, indicating a significant slowdown in the growth of supply and demand in the non-manufacturing sector from the previous month.   In terms of sectors, the business activity index and new order index of transportation, accommodation and catering, culture, sports and entertainment, and tourism-related industries all declined significantly from the previous month. 

Then the foamed concrete of the market may be affected by significant changes, the price will also be volatile, if you want to know the latest news of the foamed concrete, welcome to contact us.
