E-MENTRA® Booster: Mineral Performance Additive for Low-Carbon Concrete
E-MENTRA® Booster is an advanced mineral performance additive engineered to optimize hydration kinetics and accelerate early-age strength development in hydraulic binder systems. By promoting controlled ettringite formation and enhancing early-stage matrix densification, it is particularly effective in compensating for the slower strength development typically associated with high-replacement Supplementary Cementitious Materials (SCMs), such as Ground Granulated Blast Furnace Slag (GGBS), fly ash, calcined clay (LC³), and natural pozzolans.
Key Benefits
Early Strength Acceleration: Dramatically increases 12–24 hour compressive strength in high-SCM concrete mixtures, preventing demolding delays and boosting production turnover.
Mitigates SCM Delays: Counteracts early-age strength deficits caused by heavy clinker replacement with blast furnace slag (GGBS), fly ash, and pozzolans.
Lowers Curing Energy & Carbon Footprint: High early reactivity reduces or eliminates the need for elevated steam curing temperatures in precast manufacturing, significantly lowering energy costs and overall embodied CO2.
Autogenous Shrinkage Compensation: Supports matrix stability during initial hydration to control volume change and micro-cracking.
Typical Applications
Precast Concrete Elements: Structural components, tunnel segments, box culverts, railway sleepers, and architectural panels requiring rapid demolding.
High-SCM & Blended Concrete: Mix designs incorporating high replacement levels of GGBS, fly ash, LC³, or composite cements (CEM II, CEM III, CEM V).
Eco-Friendly & Low-Carbon Formulations: Concrete applications targeting reduced clinker content while demanding strict early-age engineering specifications.

E-MENTRA®: Premium Shrinkage-Compensating Mineral Additive
E-MENTRA® is an advanced Calcium Sulfoaluminate (CSA)-based mineral additive specifically engineered to chemically prestress concrete, providing controlled expansion during early hydration to fully compensate for drying and autogenous shrinkage. By forming controlled Ettringite phases (C6ASˉ3H32), E-MENTRA® reduces or completely eliminates shrinkage cracking, enabling the design of joint-free slabs, extended joint spacing, and high-durability concrete elements.
Formulated for high reactivity at optimized dosage rates, E-MENTRA® leverages balanced free lime (CaO) and reactive aluminate chemistry to trigger efficient expansive mineral formation early in the curing process, optimizing volume stability without compromising long-term compressive strength.
Key Benefits
Crack Elimination: Effectively neutralizes drying and autogenous shrinkage, preventing micro-cracking and macro-structural defects.
Extended Joint Spacing: Enables large continuous concrete pours, drastically reducing or eliminating the need for saw-cut control joints and traditional construction joints.
Accelerated Construction Timelines: Simplifies slab placement geometries and eliminates post-pouring saw-cutting operations for faster handover.
Enhanced Long-Term Durability: Minimizes joint breakdown under heavy vehicle traffic, reducing surface maintenance and lifecycle repairs.
Versatile Compatibility: Formulated for seamless performance in Portland cement systems (CEM I) as well as low-carbon blended binders containing SCMs (GGBS, fly ash, LC³, and pozzolans).
Typical Applications
Jointless Industrial Flooring: High-performance warehouse floors, logistics hubs, and distribution centers with high-density racking requiring smooth, seamless traffic surfaces.
Pre-Stressed & Post-Tensioned Structures: Chemically prestressed elements where controlled expansive force optimizes internal steel tensioning.
Containment & Water-Retaining Structures: Water tanks, basements, and marine infrastructure requiring high impermeability and zero shrinkage cracking.
Low-Carbon Blended Concrete: Heavy replacement binder formulations using mineral additions where early shrinkage compensation is critical.
Mechanism of Action
E-MENTRA® is proportioned directly into the concrete mix alongside primary hydraulic binders. As the concrete cures and develops matrix rigidity, E-MENTRA® drives controlled chemical expansion through early-stage ettringite formation.
When restrained by reinforcement steel or boundary conditions, this expansion generates internal compressive stresses within the concrete while placing the steel under slight tension. As subsequent drying shrinkage occurs over time, the pre-induced tension in the steel is gradually relieved, maintaining the concrete in a neutral or compressive state and preserving crack-free integrity.
ULTRA RAPID
E-MENTRA®: Ultra-Rapid Hardening & Durability Additive for Cementitious Systems
E-MENTRA® is an advanced Amorphous Calcium Aluminate (ACA)-based mineral additive designed to deliver rapid acceleration, high early-age strength, and exceptional shrinkage resistance across a wide range of temperature conditions. Unlike traditional crystalline calcium aluminate cements, E-MENTRA® utilizes a specialized amorphous mineral structure that guarantees long-term chemical stability and durability, making it fully suitable for external structural applications and high-moisture environments.
Functioning both as a performance component for site-mixed mortars/concretes and as a key raw material for specialty dry-mix formulations, E-MENTRA® enables ultra-fast setting times without sacrificing final matrix integrity or bonding performance.
Key Benefits
Ultra-Rapid Hardening: Triggers rapid hydration kinetics to deliver exceptionally high early-age compressive and flexural strengths within hours, even under cold weather conditions.
Cold-Weather Performance: Maintains reliable setting and hardening characteristics at low ambient temperatures where conventional Portland cements slow down.
Shrinkage & Crack Suppression: Significantly lowers overall shrinkage levels, providing superior resistance against initial plastic and early drying shrinkage cracks.
Superior Weathering & Moisture Resistance: The non-crystalline amorphous calcium aluminate phase prevents phase conversion issues, ensuring long-term durability in wet, humid, or exterior exposure conditions.
High Bond Integrity: Delivers strong adhesion to existing concrete substrates, structural steel, and reinforcing elements.
Typical Applications
Rapid-Setting Mortars & Repair Compounds: Water-stop formulations, emergency leak-sealing mortars, and fast-track concrete repair systems.
Specialty Dry-Mix Formulations: High-performance self-leveling underlayments (SLUs), tile adhesives, non-shrink grouts, and fast-setting screeds.
Precast & Infrastructure Repairs: Highway, runway, and industrial floor repairs requiring fast return-to-service timelines under challenging environmental conditions.
