The increasing global emphasis on sustainable construction practices has spurred significant international research into developing durable and eco-friendly concrete materials. This study investigates the potential of metakaolin glass powder as supplementary aluminosilicate materials in slag- based geopolymer mortars, aiming to enhance their mechanical properties durability. To further improve performance, polypropylene fibers were incorporated at various dosages. Therefore, 13 mixtures mortar blast furnace slag have been developed. control mix does not contain or replacement materials, whereas other formulations, employed substitutes for weight percentages (relative slag) 5% 10%, separately combination. Additionally, fiber-containing samples are divided two groups volume percentage fibers, comprising 0.2% 0.4%. results investigation show that use powder, particularly a leads an improvement 28-day compressive strength. Furthermore, mixes containing demonstrated higher flexural strength compared those metakaolin, irrespective fibers. best performance rapid chloride permeability test is associated with combination 10%. Satisfactory obtained when using this utilized fuzzy inference system predict indicate that, by considering uncertainties, can be predicted error less than 1% without need complex mathematical calculations.

Abstract The importance of using natural materials in the construction field within framework sustainable and environmentally friendly approaches is increasing day by day. In this context, study was aimed to develop a hemp fiber‐based insulating building material. boron doped fibers were characterized thermogravimetric differential thermal analysis (DTA/TGA) emission environmental scanning electron microscopy (FE‐ESEM). produced mixing undoped, 10% 15% boric acid separately with lime. fiber:binder ratio determined as 1:4 weight all samples. To determine acoustic properties samples; conductivity test heat flow plate method, sound absorption transmission loss tests impedance tube method carried out. order mechanical strength materials, three‐point bending performed. As result analyses, coefficients samples fibers, which are solution, 0.0935, 0.1926, 0.1863 W/mK, respectively; noise reduction (NRCs) measured 0.425, 0.443, 0.385, highest values recorded 27.17, 33.50, 46.92 dB, flexural ( σ f ) 1.922, 1.992, 2.578 MPa, respectively.

ABSTRACT Textile waste poses a major challenge in the 21st century, particularly for Sub‐Saharan African countries, where local production and high imports lead to excessive waste, often ending up landfills or incineration. However, opportunities recycling repurposing textile into construction materials are emerging. This study explores trends, applications implications of using industry by employing an interpretivist philosophical perspective through scientometric systematic literature review. Findings indicate dearth research on this topic within Africa, highlighting critical gap that must be addressed promote circularity regional practices. study's findings provide actionable insights use post‐consumer wastes construction, suggesting economic growth enterprises engaged innovative like ecological blocks interior features buildings, which have been less explored existing studies.

To address the pressing need for sustainable building materials, this study introduced an innovative and eco-friendly approach to manufacturing thermal-acoustic panels, utilizing agricultural waste with rice straw as primary material. Paper pulp (PP) Persea kurzii (PK) were used non-chemical binders at ratios of 50:50, 60:40, 70:30, 80:20. After mixing, all samples subjected heat-free hydraulic compression 5 bars evaluate their physical, mechanical, thermal, acoustic properties. Increasing proportion binder directly impacted panel density flexural strength while also inversely affecting porosity. The PK had a low thermal conductivity value 0.040 W/mK, proving it was good insulator high sound absorption coefficient, especially higher frequencies. RSPP-4 highest noise reduction coefficient (0.51) absorbed frequencies, suggesting its potential reduction. Microscopic analysis provided further insight into surface characteristics. PP exhibited smooth continuous fiber weave that did not obscure pores, consisted particles. correlation between characteristics performance, underscored intricate balance material Research results can be applied in construction industry develop materials offer superior These panels effectively utilize show environmentally friendly enhance indoor comfort acoustics various environments.
