Abstract

This study prepared a high-strength lightweight cementitious material by combining ultra-high performance cementitious material with marine-derived biomass waste Enteromorpha prolifera powder (EPP). The physical properties, compressive strength, pore structure, and hydration characteristics of the prepared lightweight cementitious material were studied. The results showed that the density of the specimens decreased as the EPP content increased. The minimum density of the lightweight cementitious material could reach 1320 kg/m³. Incorporating EPP significantly improves the porosity in the matrix, leading to a reduction in compressive strength. Moreover, the level of hydration and average chain length of C-S-H were enhanced with the content of EPP, and the scanning electron microscope showed a cellular pore structure inside the lightweight cementitious material. This study can provide a new path for marine-derived biomass waste EPP utilization.
