... mechanical testing and multi-scale microstructural characterisation (X-ray diffraction analysis, scanning electron microscopy, nuclear magnetic resonance, thermogravimetric–differential thermogravimetric analysis), the pozzolanic effect of fly ash, the load–damage mechanism and their coupled interaction were...

... was to develop biocomposite ceiling tiles as an alternative to gypsum ceiling tiles. To do this, different proportions (35–55%) of pearl millet seed coverings ( PMSC ) were used as a partial replacement for gypsum. Microstructural analysis was performed, followed by tests for flexural strength and thermal...

... and microstructural properties of the concretes were evaluated. The results indicate that the optimal replacement levels were 40% SSCA and 30% SSFA . At 90 days, compared with conventional concrete, the compressive strength increased by 22.8% with 30% SSFA and by 8.6% with 40% SSCA . Split tensile and flexural...
