About Sugarcrete®️

Sugarcrete, a biomaterial construction block with an interlocking shape made from the sugarcane by-product bagasse. The material was developed to be a low-cost and low-carbon reusable construction-material alternative to brick and concrete.  Created by mixing the sugarcane fibres left over after sugar sap extraction, known as bagasse, with bespoke sand-mineral binders,the material has the potential to be used and reused in new or existing structures, replacing both brick and concrete.Developed over two years, testing of the material by UEL’s SRI showed that using Sugarcrete®️, when compared to concrete production, reduces curing time to one week (a process that takes up to 28 days), is four to five times lighter than concrete block, only uses 15 – 20 percent of its carbon footprint and provides substantially reduced costs.

Why was Sugarcane used?

Sugarcane was chosen as the primary resource for the construction material due to several compelling reasons. Sugarcane holds the distinction of being the world’s largest crop by production volume, making it an abundant and readily available raw material. The sheer scale of sugarcane cultivation provides an ample supply of bio-waste, particularly bagasse, which is generated during the processing of sugarcane to produce sugar.The decision to utilize sugarcane aligns with the project’s goal of sustainable construction practices. The processing of sugarcane into sugar generates byproducts that offer a viable alternative to high energy-demanding construction systems such as concrete or brick. By repurposing sugarcane bio-waste, the project aims to reduce reliance on traditional construction materials known for their environmental impact. Moreover, sugarcane’s growth presents a highly efficient CO2-to-biomass conversion process, up to 50 times more efficient than forestry. 

Research and Development at UEL

The University of East London’s Sustainability Research Institute (SRI) plays a crucial role in the project’s research and development phase. Collaborating with the MArch Architecture program, experts delve into the scientific aspects of converting sugarcane waste into a viable construction material.

Grimshaw’s Innovative Research into Interlocking Geometries

Grimshaw’s prior exploration of interlocking geometries laid the foundation for their groundbreaking project, This research involved using the form of building components to create self-supporting assemblies, providing a unique approach to construction methods. Building on their interlocking geometry research, Grimshaw successfully deployed  Sugarcrete ® ️as a demountable, reusable, and fire-resistant composite floor slab. This innovative application allows  Sugarcrete®️ to be easily applied, disassembled, or extended within both new and existing structures.Sugarcrete®️ when integrated as a floor slab, adapts the design principles from John Abeille’s 1699 concept for dry assembly flat vaults. The system comprises interlocking components that efficiently transfer loads across the slab between blocks. These loads are restrained using post-tensioned perimeter ties, resulting in a reduction of up to 90 percent in the steel content of the slab.Elena Shilova, architect at Grimshaw, highlighted the significance of reducing steel content in the  Sugarcrete®️ slab assembly. This reduction, combined with the use of sugar cane fibers of varying densities within a modular system, mitigates the potential risks of cracking observed in traditional concrete, especially in extreme situations. The modular design of  Sugarcrete®️ absorbs the effects of seismic shock, making it particularly valuable in earthquake-prone regions where sugarcane cultivation is prevalent.The adaptability of  Sugarcrete®️ to Abeille’s design not only reduces the reliance on steel but also enhances the structural integrity of the floor slab. This is particularly crucial in earthquake-prone regions, where the material’s ability to absorb seismic shock aligns seamlessly with the characteristics vital for ensuring the safety and stability of structures.
