Recently, geopolymer binders have been considered because of low cost, simple processes for synthesis and many raw materials in nature. Geopolymer with brittle nature does not have high strength and cannot be used alone for structural materials. Therefore, to use in different structures, the composite which is reinforced with fibers such as carbon, glass, basalt, etchasbeen used. In this resear...

The mining industry generates large quantities of waste as tailings. tailings have an adverse environmental impact. This study explored the utilization and stabilization Barberton gold mine (GMTs) basic oxygen furnace slag (BOFS) to synthesize geopolymers for other applications. geochemical, chemical, geotechnical properties GMT, BOFS, GMT geopolymer, GMT: BOFS geopolymer were also studied. Sod...

Nowadays, concepts of self-cleaning have received great attention in construction building materials. Self-cleaning with the presence photocatalyst has been applied materials to overcome problem surfaces becoming dirty after exposure for a long time highly polluted areas. To date, concept green blending led development new binding material materials, which is geopolymer an addition photocatalys...

The present study aims to enhance the mechanical, microstructural, and fracture performance of alkali-activated coal ash with different proportions α-phase ultrafine Al2O3 nanoparticles. inspected nanoparticles are 0–3% by weight proportion basalt fibres (BF) added is 2% paste. Several tests carried out on cubical rectangular nanocomposites representative models geopolymer inspect their mechani...

The aim of the present work was to study influence elevated temperatures on thermal behavior geopolymer cements based incorporation metakaolin with cement kiln dust. Geopolymer composites were synthesized by partially substituted (MK) 0, 20, 30 and 40 wt% dust (CKD). mixture liquid sodium silicate (Na2SiO3) hydroxide (NaOH) used as alkaline activator solution fixed ratio 2.5 concentration 10 Mo...

Alkali silica reaction (ASR) occurs due to chemical reaction between hydroxyl ions in the pore water within the concrete matrix and certain forms of silica. This reaction could lead to strength loss, cracking, volume expansion and potentially failure of the structure. This manuscript reports findings of an experimental investigation of the inter-particle bonding between the reactive aggregates ...
