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

Gold is a high-quality hedge hedging tool, favored by investors. Especially in recent years, with the increasing instability of the world economy, gold has become one of the preferred asset allocations of investors because of its functions of hedging and fighting inflation. 

Earlier, the worsening situation in Ukraine sent gold prices soaring to a two-year high of $2,070 an ounce. But gold, along with other commodities, fell back last week as conditions changed and bulls took profits, hitting a low of $1,895 an ounce. Rising gold prices may also have an impact on the foamed concrete prices. 

According to China Business News, Goldman Sachs raised its gold price forecast in early March, considering Asian buyers' gold consumption demand, investment demand and central bank gold purchase demand continue to rise. Three -, six - and 12-month targets were raised to $2,300, $2,500 and $2,500 an ounce, respectively, from $1,950, $2,050 and $2,150. The last time all three accelerated was in 2010-11 when gold prices rose nearly 70%. 

The World Gold Council has also noted that global gold demand is at its highest level in nearly two years, which is linked to a recovery in consumption and consumer sentiment to combat inflation. 

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.

As the duration of the conflict between Russia and Ukraine grows, its impact on commodities is widening amid the tug-of-war. Recently, European and American sanctions against Russia have been issued one after another. In response, Russia has taken advantage of its role as an important supplier of many energy and commodities, requiring exports of commodities, including energy, grain, metal, and wood, to "unfriendly" countries to be settled in robles. Therefore, it is expected that the price of the foamed concrete will continue to increase.
