Susano Paper and Pulp, the Brazilia-based company that is the world's largest pulp producer, has warned that global pulp stocks have been falling sharply and are facing shortages that could lead to higher prices for necessities such as paper towels and toilet paper in the future.
Timber trade between Russia and Europe, an important supplier of timber to Europe, has been completely blocked due to the ongoing conflict between Russia and Ukraine, inhibiting the concrete additive in the future are still very uncertain.
At first, concrete additives were used only to save cement. With the development of construction technology, admixture has become the main measure to improve the performance of concrete.
What are advantages of concrete additives?
It can reduce the water consumption of concrete. Or the fluidity of concrete can be increased without increasing water consumption.
The setting time of concrete can be adjusted.
Reduce bleeding and segregation. Improve workability and water elutriation resistance.
The slump loss can be reduced. Increase the pumpability of pumping concrete.
It can reduce contraction. The addition of expansive agent can also compensate for shrinkage.
Delay the initial hydration heat of concrete. Reduce the temperature rise rate of mass concrete and reduce the occurrence of cracks.
Improve the early strength of concrete. Prevent freezing at negative temperature.
Improve strength, increase frost resistance, impermeability, wear resistance, corrosion resistance.
Control alkali-aggregate reaction. Prevent the corrosion of steel bar and reduce the diffusion of chloride ion.
Made into concrete with other special properties.
Reduce the viscosity coefficient of concrete.
Where are concrete admixtures used?
1. It is suitable for mass concrete, high-strength and high-performance concrete, roller compacted concrete, concrete constructed in hot weather, concrete poured in a large area, concrete produced by cold joints, concrete that needs to be parked or transported for a long time, self-leveling vibration-free concrete, slip form construction or horizontal construction and other concrete that needs to delay setting time.
2. It is suitable for different grades of concrete under the daily minimum temperature of 5 degrees Celsius, as well as various continuous pouring projects of high flow concrete, commercial concrete, pumping concrete, prestress and reinforced concrete.
3. It is not suitable to be used alone for concrete with early strength requirements and steam curing concrete.

Inflationary pressures on Canadians continue to rise. The consumer-price index rose 6.7% in March from a year earlier, the biggest increase since January 1991, according to the latest figures from Statistics Canada.
On a month-on-month basis, Canada's CPI rose 1.4 percent in March, also accelerating from February's 1.0 percent rise.
Prices in the eight major sectors covered by the statistics continued to rise. The uptrend comes against the backdrop of continued price pressures in the Canadian housing market, widespread supply chain constraints, and geopolitical conflicts, according to CBC. A variety of factors have affected energy, commodity, and agricultural markets. Meanwhile, Canada's employment picture continued to improve in March, with the unemployment rate falling to a record low and the average hourly earnings of employees rising.
Excluding gasoline, Canada's CPI rose 5.5 percent year on year in March. It is also the highest since comparable data began in 1999.
The widespread supply chain constraints and geopolitical conflicts are expected to continue to affect the prices of the concrete additive.
