Energy Production
Green Concrete is a family of alkali-activated aluminosilicate binders (AABs) — a Portland-cement alternative derived from slag, kaolin, and quartz sands, activated with sodium metasilicate, soda ash, and other alkalis to form C-(A)-S-H matrices.
Technology brief
Green Concrete is a family of alkali-activated aluminosilicate binders (AABs) — a Portland-cement alternative derived from slag, kaolin, and quartz sands, activated with sodium metasilicate, soda ash, and other alkalis to form C-(A)-S-H matrices.
The challenge
Decorative cements and architectural elements; dry mixes and plasters; finishing putties and façade coatings; tile adhesives; vibro-pressed and vibro-cast concretes (structural and aesthetic). Substrates: ceramic, gypsum, concrete, light aggregates.
Users: construction-materials makers, precast/architectural producers, CO₂-tax-sensitive markets.
ARBOK solution
Green Concrete is a family of alkali-activated aluminosilicate binders (AABs) — a Portland-cement alternative derived from slag, kaolin, and quartz sands, activated with sodium metasilicate, soda ash, and other alkalis to form C-(A)-S-H matrices. It eliminates clinker calcination, lowers CO₂, and delivers higher durability, faster curing, and strong adhesion using industrial by-products and less energy-intensive processing. Validated across plasters, putties, tile adhesives, and vibro-pressed/cast concretes.
Granulated blast-furnace slag and aluminosilicates (kaolin, quartz) are activated with sodium metasilicate and soda ash to form dense, pore-refined C-(A)-S-H networks — no clinker, no high-temperature sintering. Polymer modifiers and rheology control tune workability; pigments and TiO₂ give color and UV stability.
Limitations: slag/feedstock chemistry variability affects reproducibility; standardization (ISO/ASTM) and large-continuous-mixer scale-up pending.
Market and application
Cement is ~8 % of global CO₂; green-building standards and CO₂ pricing drive demand for clinker-free binders. A validated AAB family spanning decorative, finishing, and structural products — with superior adhesion and durability — addresses finishing-materials, precast, and façade markets where fast cure and visual quality matter.
Industrial by-product feedstock (slag/kaolin) and standard equipment; CO₂-tax avoidance and durability/adhesion advantages. No explicit CAPEX/OPEX/payback figures in source — flagged as missing; economics indicative until continuous-scale data.
Use cases
Decorative cements and architectural elements; dry mixes and plasters; finishing putties and façade coatings; tile adhesives; vibro-pressed and vibro-cast concretes (structural and aesthetic). Substrates: ceramic, gypsum, concrete, light aggregates.
Users: construction-materials makers, precast/architectural producers, CO₂-tax-sensitive markets.
Steps: blend slag + aluminosilicate + alkali activator + additives → mix/cast/vibro-press → cure (ambient or steam). Compatible with industrial mixers and casting lines. Remaining: scale to 2–5 t/day continuous mixers, exterior cladding/road field validation, ISO/ASTM standardization, green-building registration.
Modular precast construction; low-emission building systems; eco-certified architecture; cement replacement in CO₂-taxed markets. Complements TEG-BETON, LB HEAT, and ARBOK pigment systems.

Compressive strength: plasters 21–26 MPa (28–60 d), putties 13–20 MPa, vibro-pressed up to 60 MPa, vibro-cast 62–90 MPa. Adhesion: up to 0.65 MPa (plasters), 0.63 MPa (putties). Shrinkage: 0.5–0.7 mm/m. Frost resistance: >75–100 cycles. Workability (vibro-cast): 25–60 min. W/C (decorative): 0.35–0.40. Bulk density: 2390 kg/m³. Pigment/UV/thermal stability confirmed.
Note: product-level lab+field data exist; full standardization and continuous-scale reproducibility pending.
Binders: granulated blast-furnace slag, sodium metasilicate, soda ash. Additives: kaolin, TiO₂, polymer modifiers (methylcellulose, RHOXIMAT), marble flour, sodium gluconate. Fillers: graded quartz sand, expanded clay (lightweight), mineral pigments. Compatible with standard industrial mixing/casting equipment.
Technical: dense C-(A)-S-H matrix, no microcracks at 4 months, strong binder–aggregate interface, high frost/chemical resistance, fast cure without autoclave. Economic: industrial by-product feedstock; standard equipment; superior adhesion reduces failures. Environmental: ~70–90 % lower CO₂ (no calcination); waste valorization (slag, kaolin, ash). Aesthetic: white/pigmentable base, UV-stable color.

TRL 6 (confirmed by Michael). Demonstrated in a relevant environment: lab- and field-validated formulations across multiple product classes, pilot-scale production ready and equipment-compatible, with standardization and continuous-scale validation outstanding. (Consistent with the legacy "TRL 6–7" range, set at demonstrated-pilot.)

Slag/feedstock chemistry variability threatens reproducibility. Standardization (ISO/ASTM) and green-building certification pending. Continuous-mixer scale-up (2–5 t/day) unproven. Alkali-activator handling/safety. Construction-sector conservatism. Overlap with Geo-Polymer Arbok kept separate by feedstock/application.
