The African Development Bank will finance $25 billion by 2025 to support Africa's fight against climate change, the bank's president said at the bank's annual meeting in Accra, Ghana.
He noted that climate change has had many negative impacts on the continent, causing natural disasters such as droughts, cyclones, and floods. Climate change costs Africa between $7 billion and $15 billion a year. "Africa has no choice but to address climate change."
To ensure Africa's food supply, the African Development Bank has delivered climate-friendly seeds to 12 million farmers in 27 countries in the past two years under the "Technology for Agricultural Change in Africa" program, he said.
In the area of renewable energy, the African Development Bank is implementing a $20 billion "Desert Power" initiative in the Sahel that is expected to power 250 million people, he said.
US President Joe Biden recently wrapped up his five-day trip to Asia with a summit of leaders of the "Quad" security Dialogue.
Biden has promoted a number of economic and security cooperation initiatives during his visit aimed at deepening ties with Indo-Pacific Allies and partners in response to China's growing influence in the region. Some analysts in the United States believe the most significant announcement may be an initiative to share maritime information to combat illegal activities. But other experts say Biden's move sets a good framework for more security cooperation, though it remains to be seen whether concrete action will follow.
Affected by several factors, the supply of the early strength agent is erratic and thus its prices are expected to go higher in the future.
Triethanolamine is a colorless transparent viscous liquid at room temperature with a slight ammonia smell. It is hygroscopic and can absorb water and carbon dioxide from the air. Can be arbitrarily mixed with water and alcohol, soluble in chloroform, slightly soluble in benzene and ether. The pH of 0.1moI/L solution is 10.5. There is a risk of combustion in the event of high fever, open fire or contact with oxidants. Its aqueous solution is corrosive.
Why Can Triethanolamine Be Used As Concrete Early Strength Agent?
Triethanolamine is a commonly used early strength agent in cement industry. The function of early strength agent is to accelerate the hydration process of cement and improve the early strength in the presence of liquid phase in concrete.
Although triethanolamine does not change the hydration products of cement, it can enhance the activity of cement hydration colloid, produce pressure on the surrounding, block the capillary channel, and aggravate the role of adsorption, wetting and particle dispersion, etc. promote the formation of calcium sulphoaluminate hydrate reaction between C3A and gypsum, which can improve the compactness, impermeability and frost resistance of concrete, and play the role of early strength and strength.
When used in combination with inorganic salt materials, it can catalyze the hydration of cement itself and the reaction between inorganic salts and cement, so the effect of early strength is particularly significant.

The Free Trade Agreement between India and the United Arab Emirates (UAE) has come into force on.
The UAE is the gateway to the Middle East, North Africa, Central Asia, and sub-Saharan Africa, said Subramaniam, a senior official at India's Ministry of Commerce and Industry. The agreement will help boost bilateral trade in goods from $60 billion a year now to $100 billion a year within five years.
On 18 February 2022, India and the United Arab Emirates signed the Comprehensive Economic Partnership Agreement. With the entry into force of the agreement, 90 percent of Indian goods and 65 percent of UAE goods will enjoy tariff-free market access.
Apart from its FTA with the UAE, India is also pursuing FTAs with Australia, the UK, Canada, Israel, the European Union, and the Gulf Cooperation Council.
Influenced by international situations, the supply and prices of many early strength agent are still very uncertain.
