The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the Concrete crack reducing admixture?
Description of concrete crack reducing admixture
Cement anti-crack agent is Tongrun's full use of the physical and chemical changes in the cement curing process. The chemically synthesized powder can prevent cracking and cracking from both physical and chemical aspects, which can significantly improve the strength of lightweight concrete.
The anti-cracking agent can effectively solve the problem of the natural cracking of cement products. Adding the anti-cracking agent to lightweight concrete can reduce the cracks and hollowing of lightweight concrete, increase the strength of mortar and improve the quality of the project.
The anti-crack agent solves the problems of large shrinkage deformation, poor impermeability, and weak crack resistance of ordinary cement products. Directly incorporated into cement can effectively control the plastic shrinkage and cracks caused by segregation of lightweight concrete, significantly improving the strength of lightweight concrete cracking performance, anti-freezing, and anti-shock performance and wear resistance and earthquake resistance.
Usage of concrete crack reducing admixture
Concrete crack reducing admixture can be used to solve the crack problem of bridges, highways, runways, dams, cement products, mortar.
Especially suitable for various products of lightweight concrete.
Characteristic of concrete crack reducing admixture
(1) Crack resistance: The crack resistance agent is easily dispersed in lightweight concrete to form a three-dimensional space structure, which effectively improves the phenomenon of reduced hardening and cracking caused by too fast drying of mortar and insufficient moisture;
(2) Low shrinkage: the mixture will not shrink and settle, and the anti-crack agent can absorb internal stress and improve crack resistance;
(3)Operability: Anti-crack agent can increase the plasticity of mortar, improve construction operability and work efficiency;
(4) Anti-slip property: Because the anti-crack agent has a thickening effect, it can prevent or avoid the slippage of mortar and adherend during construction to a certain extent.
Instructions of concrete crack reducing admixture
The recommended dosage is 1.5-3kg/m3, and the precise usage needs to be determined after debugging;
When using it, it is best to dissolve the anti-crack agent in the required water, and then add it to the mixer to stir, and then it can be used.
Storage and transportation of cement anti-crack agent
(1)The anti-crack agent packaging specification is 20 kg/bag, non-toxic and non-flammable, and can be transported as general cargo;
(2)The anti-crack agent should be stored in a cool and dry place to avoid rain and moisture, and the shelf life is 24 months.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the Concrete crack reducing admixture will develop in the future is still uncertain.
