Aston University–Jesmonite cement alternatives: material insights for façade engineers
Reviewed by Tom Sullivan
First reported on The Construction Index
30 Second Briefing
Aston University is partnering with Jesmonite Ltd under an Innovate UK knowledge transfer partnership to redevelop Jesmonite’s low‑carbon acrylic, resin-based composites with added biochar as potential cement alternatives for façades and surface applications. Researchers from Aston’s Energy and Bioproducts Research Institute and Department of Civil Engineering will characterise the materials at molecular level and test mechanical and durability performance while targeting further reductions in embodied carbon. The work aims to move Jesmonite’s currently niche, film-set and design products into mainstream construction specifications, offering designers non‑cementitious façade and cladding options.
Technical Brief
- Experimental work spans Aston’s Energy and Bioproducts Research Institute and Civil Engineering laboratories, combining biochar science with structural materials testing.
- Researchers will interrogate Jesmonite composites at molecular scale to link polymer–biochar interactions with macroscale mechanical and durability behaviour.
- Data will support façade and surface product design choices such as panel thickness, fixing details and substrate compatibility in non-structural applications.
- Jesmonite’s current use in film-set structures and high-end design offers an existing manufacturing route and moulding know‑how for façade-scale components.
- Access to Aston’s “specialist facilities” implies use of advanced characterisation (e.g. spectroscopy, microscopy, thermal analysis) alongside standard civil materials tests.
- Project scope is limited to resin-based, non-cementitious systems for cladding-type elements, not primary loadbearing structural frames.
Our Take
Aston University's Energy and Bioproducts Research Institute (EBRI) typically appears in our coverage in the context of biomass and waste-to-value work, suggesting that any cement alternative emerging from this project is likely to lean on biogenic or waste-derived feedstocks rather than conventional clinker chemistry.
