Global early strength agent market trend 2023-2030 Study On Early Strength Effect of Lithium Carbonate On Mortar by Newsb-house

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 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.

Due to the limited total amount of traditional energy, people have a huge demand for cleaner and greener new energy alternatives. Now, the emergence of graphene is unlocking the possibility of its application in the energy field, which can create a greener, more efficient, and sustainable future. Here Francesco Bonaccorso, Deputy Director of Innovation at the Graphene Flagship Program, explains how his researchers have developed a series of initiatives to bring graphene from the lab to the commercial market. Graphene has become a research hotspot for new materials in the 21st century. Graphene has been adopted by many industries, the most notable of which are healthcare and key material applications.

The development of graphene has brought huge fluctuations in the demand for early strength agent, and the demand for early strength agent will continue to grow in the future. You can contact us for the latest news on early strength agent.
