## Summary

The procurement process for the project titled "Steam-slaked lime - Phase III" is being conducted by Historic England Limited, aimed at researching the properties of mortars made with steam-slaked lime compared to other types of lime. This contract falls under the research services category (CPV: 73110000) and is located in England. The procurement stage is currently in the Award phase, with a contract value of £34,158.28. The award was finalised on 16 January 2022, and the contract period commenced on 17 January 2022, extending until 16 August 2022. The procurement method used was a direct procurement, specifically a single tender action below the threshold.

This tender presents an excellent opportunity for businesses involved in materials research, construction, or civil engineering to engage with Historic England Limited. Small and medium-sized enterprises (SMEs) with expertise in the production and testing of construction materials would be particularly suitable to compete, given their potential agility and specialised knowledge in this niche. Participation in such research projects can lead to further collaboration opportunities and advancement in product offerings, enhancing business growth prospects.

## Notice

This purchase is for Phase III of research to investigate the role of steam in the hydration (slaking) of calcium oxide (quick lime) and how this influences the properties and performance of steam-slaked lime and how this in turn affects mortar performance. Phase I, carried out in 2018, determined that steam-slaked lime has a significantly different microstructure compared to lime slaked in other ways. Phase II (commenced in 2020, but is only just being completed because of delays due to coronavirus restrictions) has shown how these microstructural differences affect water demand, water retention and carbonation of mortars made with steam-slaked lime. It is proposed that Phase III will consider in more detail the properties of mortars made with steam-slaked lime compared to mortars made with different types of lime, focussing in particular on permeability and moisture transport properties, and frost and salt resistance.
