Alkali-Activated Slag for Marine Construction — PatSnap Eureka
Alkali-Activated Slag Materials for Marine Construction: Landscape 2026
A transparent audit of the retrieved patent dataset reveals a critical mismatch: all 60+ records cover polylactic acid (PLA) polymer science — not alkali-activated slag or marine construction. This report documents the discrepancy and provides the correct query methodology for IP professionals.
What the Retrieved Dataset Actually Contains
A thorough review of the data provided for this research query reveals a significant mismatch. All retrieved records cover PLA polymer science — none cover the requested AAS marine construction topic.
The retrieved dataset encompasses approximately 60 records, with dominant assignees including Synbra Technology B.V. (expandable PLA foams), LG Hausys Ltd. (PLA-based boards and foam sheets), Northern Technologies International Corporation (high-impact PLA blends), and Wisys Technology Foundation (PLA-lignin 3D printing composites). The dominant technical themes are PLA toughening via reactive blending, biobased plasticizers, and biodegradable packaging.
None of these records contain data on slag activation chemistry, alkali activators (sodium silicate, sodium hydroxide, potassium hydroxide), fly ash blends, chloride resistance, sulfate resistance, pozzolanic reaction products, or any marine durability performance metrics associated with cementitious systems. For context on materials standards relevant to marine infrastructure, the ISO and ASTM International maintain the governing standards for slag cement and marine durability testing.
Fabricating AAS or marine construction claims from PLA polymer data would constitute scientific misrepresentation. PatSnap Analytics is designed precisely to prevent this type of cross-domain data contamination by enabling targeted IPC-code-level searches before any landscape synthesis begins.
PLA Polymer Sub-Themes in the Dataset
The dataset addresses poly(lactic acid) modification across four distinct sub-themes, none of which are germane to alkali-activated slag chemistry or marine structural applications.
Toughening via Reactive Blending
Use of ethylene-acrylic ester-glycidyl methacrylate terpolymers, polysiloxane-containing PLA copolymers, and hyperbranched polyesters. Demonstrated by Northern Technologies International Corporation (2022) and academic literature (2017). This is wholly unrelated to slag chemistry or marine binder science, as confirmed by the EPO IPC classification system.
Northern Technologies International CorporationBiobased Plasticization
Including epoxidized vegetable oils and lactic acid oligomers, as covered in academic literature on epoxidized Jatropha oil as a sustainable plasticizer to poly(lactic acid) (2017). No connection to alkali activators or marine durability metrics exists in these records.
Academic literature, 2017Expandable PLA Foam for Packaging and Horticulture
Multiple patents from Synbra Technology B.V. (2012–2017) describe coated particulate expandable polylactic acid and related foam articles. LifoAm Industries, LLC (2024) contributed records on impact properties of expandable polylactic acid molded foam articles — none applicable to marine binder research.
Synbra Technology B.V. · LifoAm IndustriesPLA-Lignin Composites for 3D Printing
Including work by Wisys Technology Foundation, Inc. (2020) on polylactic acid and lignin composite thermoplastic for 3D printing. Academic literature (2019) on super toughened poly(lactic acid)-based ternary blends via enhancing interfacial compatibility is also present. Neither sub-theme relates to geopolymer binders or coastal infrastructure.
Wisys Technology Foundation, Inc., 2020What a Credible AAS Marine Construction Landscape Requires
The research question requires data on five distinct technical and commercial domains, none of which appear in the retrieved dataset.
How to Retrieve the Correct AAS Patent Dataset
IP professionals and R&D leads seeking the AAS marine construction landscape should use the following IPC codes and keyword clusters in their patent database query.
A correct patent query for alkali-activated slag materials in marine construction must target IPC subclass C04B, specifically codes for slag cements, geopolymers, and alkali activation. Patent records should be sourced from Espacenet, USPTO, or CNIPA. Literature should be drawn from journals including Cement and Concrete Research, Construction and Building Materials, Journal of Hazardous Materials, and Marine Structures.
The keyword clusters required are: “alkali-activated”, “ground granulated blast furnace slag”, “geopolymer”, “marine durability”, and “chloride resistance”. The assignee landscape for AAS marine materials — which would include cement producers, national laboratories, and university technology offices — cannot be characterised from the current dataset, as confirmed by the absence of any relevant record. PatSnap’s chemicals and materials solution supports targeted IPC-level retrieval to avoid this type of mismatch.
Standards compliance data should reference EN 15167 (ground granulated blast furnace slag for use in concrete), ASTM C989, and ISO 16204. The WIPO IPC classification browser can be used to verify the correct subclass codes before query construction.

What This Data Quality Alert Means for IP Practitioners
Six verified takeaways from the dataset review — all traceable to the retrieved records.
Zero AAS Records in 60+ Retrieved Documents
The dataset provided contains no information relevant to alkali-activated slag (AAS) materials or marine construction applications. All 60+ records exclusively address polylactic acid (PLA) polymer science.
Dominant Theme Is Reactive Melt Blending of PLA
The dominant PLA toughening theme in the dataset is reactive melt blending, as shown in super toughened poly(lactic acid)-based ternary blends via enhancing interfacial compatibility (2019), which is wholly unrelated to slag chemistry.
Retrieved Dataset Composition at a Glance
Two charts illustrating the composition of the retrieved dataset — confirming the complete absence of AAS or marine construction content.
Dataset Composition by Technology Domain
100% of retrieved records address PLA polymer science. Zero records address AAS or marine construction.
PLA Sub-Theme Distribution Among Retrieved Records
Reactive blending is the dominant theme; all sub-themes are unrelated to AAS or marine construction.
Producing a Credible AAS Marine Construction Landscape
The following data sources and methodology are required to produce an evidence-based landscape article on alkali-activated slag materials for marine construction.
Alkali-Activated Slag for Marine Construction — key questions answered
Alkali-activated slag (AAS) refers to binder systems formed by activating ground granulated blast furnace slag with alkali solutions such as sodium silicate or sodium hydroxide. For marine construction, AAS is of interest for its potential chloride ion penetration resistance, sulfate attack resistance, and corrosion protection of embedded steel — properties critical for coastal infrastructure, offshore structures, and port engineering.
The dataset retrieved for this research query contained approximately 60 records exclusively covering polylactic acid (PLA) polymer technologies — including toughening strategies, packaging films, foam products, and 3D printing composites. None of the records pertained to alkali-activated slag chemistry, geopolymer binders, or marine construction applications.
A correct patent query for AAS marine construction should target IPC subclass C04B, specifically C04B 28/08 (slag cements), C04B 18/14 (granulated blast furnace slag), and C04B 7/153. Keyword clusters should include alkali-activated, ground granulated blast furnace slag, geopolymer, marine durability, and chloride resistance.
The dominant assignees in the retrieved dataset are Synbra Technology B.V. (expandable PLA foams), LG Hausys Ltd. (PLA-based boards and foam sheets), Northern Technologies International Corporation (high-impact PLA blends), and Wisys Technology Foundation (PLA-lignin 3D printing composites). None of these assignees operate in the alkali-activated slag or marine construction space.
Credible literature sources for alkali-activated slag in marine construction include Cement and Concrete Research, Construction and Building Materials, Journal of Hazardous Materials, and Marine Structures.
Standards relevant to alkali-activated slag materials include EN 15167 (ground granulated blast furnace slag for use in concrete), ASTM C989, and ISO 16204. These standards define performance requirements for slag cements and supplementary cementitious materials.
