Kaber: Redefining AAC Gassing Stability Through Scientific Surface Encapsulation

At Kaber, we don’t just manufacture aluminum paste—we engineer the microscopic pore architecture of Autoclaved Aerated Concrete (AAC/ALC).

As a technology-driven enterprise specializing in high-performance additive solutions for next-generation building materials, Kaber stands at the absolute forefront of materials science. We understand that in complex AAC production, a mere 1°C temperature shift or a minor fluctuation in quicklime slaking velocity can drastically jeopardize your qualification yield. Therefore, Kaber rejects rigid, one-size-fits-all commodities. Instead, we are fully committed to delivering highly precise, tailored gas evolution solutions engineered specifically for your plant's unique environment.

PRODUCT PORTFOLIO

Water-Based AL Paste

High-Activity Series optimized for lightweight blocks (D300–D450).

Classic Series engineered for standard and high-density blocks, providing highly predictable reaction kinetics and robust matrix stability.

AL Paste for ALC Panel

Highly restricted Particle Size Distribution (PSD) for high-density structural metrics (D550–D650), permanently wiping out local density variances and internal micro-cracks.

Foaming Agents

Lower the surface tension of the watery cementitious phase. Preventing bubble coalescence (merging) and ensuring a high ratio of independent closed pores.

Integrated Additive

Shield your production from regional material fluctuations (erratic quicklime reactivity or clay-heavy silica sand). Prevent watermark streaks, and reduce overall binder costs by maximizing the efficiency of your existing matrix.

Our Engineered Solution: Density-Specific Passivation Technology

We understand that one-size-fits-all aluminum paste does not exist. Our R&D center has developed specific interfacial passivation coatings to perfectly match your target densities and local raw material profiles:

For D300-D400 : Delays the initial gas evolution, allowing the ultra-thin slurry enough time to build baseline shear strength. Once the skeleton is ready, the gas expands smoothly, guaranteeing zero collapse and a highly uniform, closed-cell structure.

For D550-D650: We optimize the particle size and use a rapid-activation hydrophilic treatment. This ensures the gas evolution completes fully before the dense matrix hardens, eliminating internal micro-cracks and maximizing the ultimate load-bearing capacity of your ALC panels.

Ultra-Lightweight Blocks ➔ The Risk of Slurry Collapse

The Mechanism: To achieve low density, the formulation requires high water content and a large volume of aluminum paste, resulting in extremely thin pore walls and exceptionally low initial shear strength in the slurry.

The Failure: If the aluminum paste reacts prematurely (before the slurry builds enough structural skeleton to "hold" the bubbles), the fragile pore walls rupture. The gas escapes rapidly (boiling), leading to catastrophic slurry collapse and massive, interconnected pores.

Structural ALC Panels ➔ The Risk of Internal Cracking

The Mechanism: High-density formulations have a low water-to-solid ratio. The slurry thickens and loses its plasticity very quickly.

The Failure: If the aluminum's gas generation is delayed and lags behind the rapid thickening curve, the gas attempts to expand inside a matrix that is already rigid. This internal pressure causes hidden gas-holding cracks, severe structural deformation, and compromises the compressive strength required for structural panels.

Precision Particle Size Distribution (PSD)

Advanced Hydrophilic Modification

Enhanced Compressive Strength

Dramatically improves the strength-to-weight ratio, allowing your D550/D650 panels to easily exceed stringent international load-bearing standards.
Optimized Binder Costs

By relying on a superior structural matrix rather than just adding more cement, manufacturers can optimize their raw material formulations without sacrificing structural integrity.
Improved Frost & Moisture Resistance

The high percentage of tiny, isolated closed cells creates an impermeable barrier, significantly enhancing the durability and weather resistance of the final panels.

Overcoming Regional Material Volatility & Climate Dynamics

Thermal & Seasonal Climate Adaptation

The ambient climate of your plant directly disrupts the baseline pouring temperature of the slurry, shifting the critical window where gas generation must occur.

Solution：We calibrate our proprietary interfacial coating layers to serve as a chemical induction shield. For hot climates, the shield compresses early gas release; for cold climates, it accelerates activation. This guarantees a stable, predictable kinetic curve whether your facility is operating at 35°C or 15°C.
Kinetic Alignment with Volatile Quicklime Reactivity

Quicklime (CaO) is the chemical engine of slurry thickening, but its reactivity profile varies drastically from quarry to quarry based on burning degrees and purity.

Solution： Our R&D team fine-tunes the surface passivation of the aluminum flakes to achieve parallel hydration curves. We synchronize the aluminum’s gas completion time precisely with your local lime’s peak thickening threshold, completely eliminating the structural mismatches that cause internal defects.
Rheological Calibration for Diverse Silica & Sand Sources

The mineralogical purity, clay content, and fineness of local quartz sand or fly ash dictate the water retention capability and the absolute water-to-material ratio of your formulation.

Solution：Introduce specialized surface-tension modifiers and hydrophilic agents to improve the suspension stability of the aluminum flakes within high-water rheologies. It ensures that even in highly fluid slurries, the aluminum particles remain uniformly dispersed without clumping or repelling water, permanently wiping out watermark streaks and localized density variances.
Plant-Specific Process & Cycle Mechanical Matching

Beyond raw materials, the mechanical configuration of a plant—including high-shear mixing speeds, mold dimensions, pre-curing static retention times, and the presence of reinforced steel meshes for ALC panels—creates a unique physical ecosystem.

Solution： We know - how about AAC production, By engineering a low-friction, high-buoyancy bubble matrix, our paste enables the slurry to flow effortlessly around complex internal steel reinforcements, ensuring flawless volume expansion and perfect structural integrity across all mold sizes.

Consistency

Predictablility

Consistency

In practical AAC manufacturing, we prioritize the stability of output quality above all else. Kaber employs a finely-tuned reaction rate balancing technology, specifically designed to eliminate common industry issues like 'slurry collapse.' By ensuring a smooth and controllable gas evolution process, we help our clients avoid the operational headaches of frequent formula adjustments due to raw material batch variations. For your production efficiency, this absolute batch consistency is the real economic value.

Replacement

We recognize that production variability is the biggest hidden cost for a plant. Kaber guarantees batch-to-batch consistency that allows you to standardize your production protocols once and for all. Our rigorous control of PSD isn't just about data; it’s about ensuring that every shipment delivers the same structural density and expansion rate as the last, turning your production line into a stable, high-yield operation.

Predictability

For ALC panel production, the core technical factor isn't the chemical composition, but the precision of the 'Hydrogen Evolution Curve.' Kaber's flagship Active series is engineered to deliver a fully controllable, constant gas evolution within 14 minutes. By locking down D50 and D95 parameters, we eliminate the risk of large pores caused by oversized particles. This ensures structural integrity around the steel reinforcement mesh, effectively reducing cracking and mold-collapse rates. We are providing more than just a raw material; we are providing a standardized process solution to guarantee your production yield.
