LifeTech ® Ultrafines Admixture

CAS No. 554-13-2

QS-PDS-800 Revision: 05

Date of Last Revision: September 13, 2022

Formula: Li2CO3
Appearance: An odorless, white powder. Lithium carbonate basedadmixture.
Application: LifeTech ultrafines is the finest of the LifeTech grades oflithium carbonate available from Livent. Because of its fineparticle size and narrow particle size distribution, this producthas been chosen as the grade of choice where reactivity andperformance are based on the surface area of the lithium
carbonate particles providing controllable, uniform andpredictable rates of reaction. Since it is the finest of thegrades, it is also the most reactive in these situations. If aslower reaction is desired, the other LifeTech grades shouldbe evaluated in use.
Cementitious Systems
LifeTech ultrafines 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 aluminaportland cement blends. Common applications for HAC andHAC/PC blends include:- Shotcrete / gunite- Refractory cements- Self-leveling floor systems - Quickset adhesives- Rapid-repair materials- Quickset mortars

The dosage of LifeTech
ultrafines depends on
the type of cementitious
system in use, as wellas the cement factor of
the mix design.
LifeTech ultrafinesprovides anaccelerating effect byincreasing the rate ofcement hydration at an
early age. In thepresence of LifeTech
ultrafines, compressive
strength begins todevelop immediately.
The desired setting time
can be adjusted bychanging thedosage rate (See figure 1). For example, in a HAC system,
the setting time can be adjusted to several seconds. Ingeneral, LifeTech ultrafines is significantly more reactive
than technical grades of lithium carbonate.
In general dosages of 0.01-0.05 % are sufficient for pure
HAC systems, and addition rates of LifeTech ultrafines
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 ofLifeTech ultrafines 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 finesprovides a uniform set throughout the mix not achievablewith grades that provide a wider particle size distribution.
OtherThe unique properties of LifeTech ultrafines have made thisproduct the grade of lithium carbonate of choice in a numberof 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 quantitiesof LifeTech ultrafines are needed than other grades of lithium
carbonate. Testing should be conducted in the application tooptimize dosage when substituting LifeTech ultrafines foranother grade of lithium carbonate.
