The data is available in the article ( ).In the following post, I will discuss papyrus and its function in the history of writing and documentation. After cooling, the CWRA and CPA were sampled in airtight polythene bags for microscopic analysis using Laser Diffraction Spectroscopy (LD) for Particle Size Distribution (PSD), FT-IR, XRF spectroscopy, and SEM. The CWR and CP were sun-dried and burned on a hard surface to avoid contamination by foreign materials. Further details of the locations are provided in Table 3. Particle size distribution (PSD) data were obtained using laser diffraction (LS) mastersizer 2000.FT-IR spectra were obtained using BRUKER TENSOR 27 in 4500–500 cm −1.The chemical compositions of CWRA and CPA were characterised by the X-ray fluorescent (XRF) BRUKER model S8 TIGER XRF spectrometer.The Scanning Electron Microscope (SEM) data, the Hitachi FlexSEM 1000, was used after gold plating.Ĭommon Water Reed ( Phragmites australis) were obtained on the banks of River Kafue in Zambia, while Cyperus papyrus (CP) was obtained from the banks of the River Nile in Uganda. Particle size distribution, spectroscopic, and microscopic data used to classify lignocellulosic bio-pozzolans for engineering applications are explored. This data helps characterise and evaluate CWRA and CPA's potential as pozzolanic materials, especially as road construction materials, and will be beneficial for other scientists to better understand unprocessed CWRA and CPA mineral information development biologically inspired materials for biologically inspired materials sustainable development across many disciplines. Therefore, the current data paper provides Laser Diffraction Spectroscopy (LD) for Particle Size Distribution (PSD), Fourier-transform infrared spectroscopy (FT-IR), X-Ray Fluorescence (XRF), and Scanning Electron Microscope (SEM) data for unprocessed CWRA and CPA in the form of tables, micrographs, and figures for microscopic analysis. However, these ashes are highly heterogeneous when they undergo microscopic analysis. There has been the belief that these pozzolanic materials are homogenous. In contrast, the lignocellulosic plants’ ashes include common water reed ash (CWRA) and cyperus papyrus ash (CPA). The agrowastes ashes include rice husk ash (RHA), sugarcane bagasse ash (SCBA), and corn cob ash (CCA), among others. This has led to a lot of research focussing on the valorisation of agricultural wastes and less economical, no-food lignocellulosic plants in producing sustainable and environmentally friendly cementitious materials commonly known as Supplementary Cementitious Materials (SCMs). Therefore, there is a need to use sustainable materials to make cementitious materials to achieve sustainable construction. Consequently, limestone, the primary material used to produce OPC, is non-renewable. Currently, there are a lot of discussions on the production of sustainable cement for construction purposes, unlike the conventional ordinary Portland cement (OPC), as its production, transportation, and application contribute to the generation of greenhouse gases, hence, climate change.
