Explore our range of lithium-based products from Livent that are specifically engineered to meet the particle size and cost efficiency needs of modern building materials.
Lithium salts are known for their improved performance, quality, and endurance to building and construction materials such as concrete, glass, and ceramics. The chemistries also provide unique characteristics and physical properties, which makes it ideal for use in a broad spectrum of industrial applications, from space suits to submarines, from lithium greases to air filtration systems.
Building Materials and Cementitious Systems:
Lithium carbonates are typically used in building materials and cementitious systems to adjust and accelerate the setting time. LIFETECH® admixtures are one of the best performance lithium carbonates in the market due to their fine particle size and narrow particle size distribution. LIFETECH® lithium carbonates provide controllable, uniform, and predictable rates of reaction when used in cementitious systems such as high-alumina cement (HAC) and alumina-portland cement blends (HAC/PC).
LIFETECH® Lithium Carbonates provide an accelerating effect by increasing the hydration rate of cement products at an early age. Cement products made with LIFETECH® Superfines or Ultrafines exhibit immediate compressive strength and accelerated setting time that can be controlled by adjusting the addition level of the lithium carbonate.
Lithium Carbonates from Livent provide a uniform set throughout the mix, which is not achievable with competitive materials or broader particle size lithium carbonates. They contain no sodium or potassium alkalis, which are known to promote alkali-silica reaction (ASR) in cementitious systems that contains reactive silica minerals. The products will also help you suppress the ASR reaction in concrete.
Typical applications of LIFETECH® Lithium Carbonate Admixtures:
99% lithium carbonate (Li2Co3) with medium-fine particle size. LIFETECH® Superfines is typically used in concrete, ceramics, and glass applications due to its reactivity and narrow particle size distribution.
99% lithium carbonate product (Li2Co3) same as Superfines, but it provides the finest particle size and the highest reactivity of lithium carbonate grades. It is excellent for use in building materials and industrial applications.
An additive for use in specialty glasses and ceramics that meets ACS reagent grade specifications. It contains a minimum of 99% lithium carbonate by weight.
Typical Dosage of LIFETECH® Lithium Carbonate Admixtures:
The dosage of LIFETECH® Lithium Carbonate Superfines and Ultrafines depends on the type of cementitious system and the mix design factor.
LIFETECH® Lithium Carbonate Superfines or Ultrafines at 0.01-0.05 is typically a sufficient level of use for pure high-alumina cement (HAC) systems. An additional dose is generally required when used in HAC/PC mixtures. A higher dosage is also needed when the HAC level is decreased in alumina-portland cement blends (HAC/PC).
LifeTech Superfines, or Ultrafines at 0.02%, achieved the desired set time in pure HAC systems while an additional 0.5-1.0% was required in higher in cement blends containing 10% (HAC).
Other Lithium Applications:
In the manufacturing of glass, ceramics, and specialty building materials, Lithium carbonates are added to lower the melting point and reduce the energy needs for optimal cost efficiency.
