Global early strength agent market trend 2022-2027 Study On Early Strength Effect of Lithium Carbonate On Mortar by Newscupcakemadrid

A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including early strength agent.

Mortar early strength agent is an important mortar additive, which has an important influence on the performance of mortar. it can improve construction efficiency and save construction cost.

Lithium carbonate is a kind of inorganic compound with chemical formula Li2CO3, which is colorless monoclinic crystal or white powder. The density is 2.11g/cm3. Melting point is 618℃(1.013*10^5Pa). Soluble in dilute acid. It is slightly soluble in water, and its solubility in cold water is higher than that in hot water. Insoluble in alcohol and acetone. It can be used to make ceramics, drugs, catalysts and so on. 

Lithium salt early strength agents can promote the setting and early strength of cement mortar. The results show that lithium salt early strength agent shortens the hydration induction period by accelerating the rupture of hydration protective film, improves the low temperature hydration ability of cement mortar, obviously shortens the low temperature thickening time, and improves the low temperature compressive strength of cement mortar. it shows excellent effect of early strength at low temperature. 

Because portland cement is often used in mortar, it is characterized by low strength at early stage and high strength at later stage. In order to improve its early strength, adding an appropriate amount of lithium carbonate to the product is very beneficial to improve its early strength.

In mortar products, lithium carbonate is mainly used in grouting materials, cement-based plastering mortars, repair mortars, seat pastes and other products. In order to improve the early strength, high alumina cement is usually added to the mortar as a setting accelerator, and antifreeze is needed in the low temperature environment. Lithium carbonate has dual functions, which can not only accelerate the hardening speed of cement and improve its early strength, but also avoid the problem of slow setting speed in winter construction or in low temperature and humid environment, so that cement products can be put into use as soon as possible. Lithium carbonate especially makes a great contribution to the early strength. In summer, the amount of lithium carbonate is usually 0.01%-0.03% of the quality of cement, while in winter, the amount of lithium carbonate should increase appropriately with the decrease of temperature, and the amount is about 0.02%-0.05%. The amount of lithium carbonate should not be too high, otherwise it will lead to cracking. 

In addition, the performance of lithium carbonate to improve the early strength of mortar is not proportional linear. With the increase of the amount of lithium carbonate, the enhancement of its strengthening effect is no longer obvious.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".  

In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.  

The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.  

As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.  

Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV.  Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
