U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the foam concrete,foaming agent,concrete curing agent will also increase.
To study the problem of collapse mode cracking in the cast-in-place foam concrete wall, using ordinary Portland cement, fly ash, and self-made composite foaming agent as the primary raw materials, the admixtures (there are two kinds of admixtures) were studied through single-factor experiments. One is a foaming agent, and the other is concrete curing agent.
According to the characteristics of the foaming agent that the foam pore size can be adjusted freely, and the preparation is atomized and diluted during use. The pore size is more acceptable and uniform (the pore size is less than 1mm). The light foam and slurry are mixed to make a lightweight concrete microporous slurry. The porosity in the slurry accounts for 70% of the total volume of the foamed concrete. The foams in the slurry are closed by a water film. They are not connected, which improves the problem of high water absorption in traditional concrete and improves the frost resistance and impermeability of foam concrete. It has a specific activation effect on fly ash.
The slurry in the pouring and forming stage has self-leveling characteristics, good pore structure, smooth entry into the mold, and rapid thickening and forming. Ensure the stability of expansion and improve the strength of foam concrete blocks. Foamed concrete has excellent properties such as lightweight, heat preservation, heat insulation, sound insulation, etc., and it has low production investment. It can use a large amount of industrial waste residue. Its application is of great significance to building energy conservation and environmental protection, so it will gradually replace concrete construction.
According to previous studies, with the increase of fly ash content, the amount of cement decreases, and the early compressive strength of concrete drops significantly. However, fly ash has pozzolanic activity, and in an alkaline environment, with the increase of concrete age, the compressive strength of high-volume fly ash foam concrete will increase significantly. In addition, the large amount of fly ash dramatically reduces the number of harmful pores, improves the compactness of the slurry structure, and is beneficial to the later strength increase.
In recent years, the application of foamed concrete has developed rapidly, but there are still a series of problems in the cast-in-place foamed concrete insulation wall:
(1) Foam concrete has low strength and is not suitable as a load-bearing wall material;
(2) Prefabricated blocks increase the process and engineering costs;
(3) Dry shrinkage of foam concrete and cracking caused by dry-wet cycle and loose structure, due to the problems of collapsed form and easy carbonization due to the influence of pouring height, seriously restrict the broad application of foam concrete.

A preparation developed in China; the comfort and the multifunctional properties of nanomaterials make "dead skin" capable of sensing again. Electronic skin is artificial skin that mimics the function of human skin. Recently, the world-renowned journal Advanced Science reported a simple and highly programmable electronic skin on a leather substrate developed by a Chinese team, which combines the natural complex structure of leather, the comfort of wearing, and the multi-functional properties of nanomaterials. , so that the "dead skin" has the ability to sense again.
In the future, foam concrete,foaming agent,concrete curing agent will be used in various high-tech fields, and the market demand for foam concrete,foaming agent,concrete curing agent will also be great. Please contact us for more information on foam concrete,foaming agent,concrete curing agent.
