LifeTech ® Superfines Admixture
Date of Last Revision:  September 15, 2022 Formula:   Li2CO3 Appearance: An odorless, white powder. Lithium carbonate based admixture.
Cementitious Systems LifeTech superfines is a chemical admixture that can be used to adjust and accelerate the setting time of cementitious systems such as high-alumina cements (HAC) and alumina- portland cement blends. Common applications for HAC and
The dosage of LifeTech superfines depends on 2:30 the type of cementitious 2:00 system in use, as well 1:30 as the cement factor of the mix design. LifeTech superfines provides an accelerating effect by increasing the rate of cement hydration at an early age. In the presence of LifeTech superfines, compressive strength begins to develop immediately. The desired setting time can be adjusted by changing the dosage rate (See figure 1). For example, in a HAC system, the  setting time can be adjusted to a few minutes. In general,  LifeTech superfines is more reactive than technical grades of lithium carbonate. In general dosages of 0.02-0.05 % are sufficient for pure HAC systems, and addition rates of LifeTech superfines should be increased as percentage of HAC in HAC/PC mixes is decreased. For example, in mixes containing 10% HAC, set times similar to those obtained at 0.02% addition of LifeTech superfines in pure HAC systems may need addition rates of 0.5-1.0 %. All addition rates are based on total cementitious amount. Our technical experts can provide assistance on dosage based on intended use. LifeTech superfines provides a uniform set throughout the mix not achievable with grades that provide a wider particle size distribution. LifeTech superfines is a chemical admixture containing essentially no sodium or potassium alkalis, which are known to promote alkali-silica reaction (ASR) in cementitious systems containing reactive silica minerals. LifeTech admixture is based on lithium, which is known to suppress the ASR reaction in concrete.

Other
The unique properties of LifeTech superfines have made this product the grade of lithium carbonate of choice in a number of other applications such as in manufacture of ceramics, welding rods, refractory materials, and specialty glasses. Dosage rates vary widely depending on the application. Because this product is more reactive due to its reduced particle size in these applications, in general, lower quantities of LifeTech superfines are needed than coarser grades of lithium carbonate. Testing should be conducted in the application to optimize dosage when substituting LifeTech superfines for another grade of lithium carbonate. Product Specifications:
