Main Performance of Foam Concrete

A recent poll in Britain found that public support for sanctions against Russia is falling as fuel and prices rise.  

The proportion of people willing to accept higher fuel prices as a result of western sanctions against Russia fell 14 percentage points to 36% from 50% in March, according to a survey conducted for the Telegraph by consultancy Redfield & Wilton Strategies.  

Global energy and fuel prices have soared since the start of the year and remain high because of the conflict between Russia and Ukraine and uncertainty over Russian supplies.  

The survey also found that 54% of people believe their own financial situation has worsened in the past year, up 12 percentage points from 42% two months ago. Sixty-two percent think things will get worse in the year ahead. Less than a third of respondents said they had received a pay rise to keep up with inflation, with two-thirds of those saying it was not enough to keep up with rising living costs.  

The figures suggest that public concern about the conflict with Ukraine is now likely to be overtaken by financial worries.  

Separately, the UK's consumer price index rose 7 percent this month from a year earlier, the highest since March 1992, according to figures released recently by the Office for National Statistics. In addition, a separate report released a few days ago by the Centre for Economics and Business Research said that real household disposable income in the UK will fall by 3% in 2022, equivalent to a loss of £2,320 per household, which would lead to the biggest drop in living standards since the 1950s. That is mainly because wages aren't keeping up with rising energy and fuel costs.  

The prices of other commodities like the concrete foaming agent are also expected to be influenced.

Lightweight 

Foam concrete has a low density. In practical application, the density grade of ordinary foam concrete is 300 kg/m3~1200kg/m3. In recent years, ultra-lightweight foam concrete with low density has also appeared, but it has not been widely used in construction engineering. In practical engineering, the density of foam concrete can be reduced to 200 kg/m3~700 kg/m3. 

Due to the low density of foam concrete, it is applied to the building's inner and outer walls, layers, layers, columns, and other parts, can reduce the weight of the building by about 25%, and some can even reduce the weight of up to 34%. In addition, the bearing capacity of structural members can be improved by using foam concrete instead of ordinary concrete. Therefore, the rational use of foam concrete in construction engineering can not only ensure the durability of the building and the bearing capacity of the structure, but also greatly reduce the cost of the project, and has significant economic benefits and broad market prospects. 

Good insulation performance 

The good thermal insulation performance of foam concrete is determined by its internal structure. By observing the internal structure of foam concrete, it can be found that the foam concrete is filled with a large number of closed and uniform small round holes.  These pores maximize the fixation of air, resulting in low thermal conductivity and good insulation. The excellent thermal performance of foam concrete is not possessed by ordinary concrete. The thermal conductivity of foam concrete with common density grade of 300kg/m3~1200kg/m3 is 0.08W/(m·K)~0.3W/(m·K). If this kind of foam concrete is widely used in building roofing material and wall material, it will produce a good energy-saving effect.

Excellent sound insulation and fire resistance performance

As a kind of porous material, foam concrete contains a lot of closed pores and has good sound insulation performance. Therefore, foam concrete can be widely used on building floors, highway sound insulation boards, underground building top floors, and other building parts, as a sound insulation layer. At the same time, foam concrete also has the general characteristics of inorganic materials, that is, not easy to burn, and has good fire resistance. A large number of research data show that the dry bulk density of foam concrete is in the range of 500 kg/m3 to 900 kg/m3, the compressive strength is in the range of 2.5 Mpa-7.5 MPa, the fire resistance of foam concrete can reach 2.7h, the sound insulation performance can reach 20dB, and the impact resistance can reach 100dB. It is a kind of high-quality soundproof refractory material that can be promoted vigorously. 

Good seismic performance 

Because of its special porous structure, foam concrete has the characteristics of low density, lightweight, and low elastic modulus. These characteristics make the foam concrete structure bear less seismic force and the propagation speed of vibration waves are much slower than that of the ordinary concrete structures. According to seismology, the longer the seismic period, the faster the shock energy is absorbed by a building structure. Therefore, foam concrete has an excellent damping effect. Appropriate application of foam concrete in specific parts of construction engineering can effectively improve the seismic performance of buildings, and enhance the safety and robustness of seismic buildings. 

Foam concrete not only has a variety of excellent performance, but in the production process can also be mixed with a large number of industrial waste, not only effective use of resources, waste into treasure, conducive to environmental protection but also greatly reduce the cost of foam concrete.

Russia's Rokot-M carrier rocket is scheduled to launch for the first time in 2024. 

The first launch of the Rokot-M carrier rocket is planned for 2024 from the Plesetsk cosmodrome, the general manager of the Khrunichev National Space Research and Production Center told TASS. The Rokot-M, a lightweight carrier rocket powered by liquid fuel, began development in 2018, with The Russian side using domestic components instead of Ukrainian components.
