This study investigates the effect of super absorbent polymers (SAPs) and glass fiber (GF) additions on the properties of lightweight concrete. The SAPs act as a pore-forming agent, with the addition of various GF contents (0.1–1.0% by weight of dr

Mechanical activation is known to greatly influence the reactivity of fly ashes. In this paper, we report a comparative study of the properties of alkali-activated geopolymer materials prepared using both ball-milled and attrition-milled fly ashes. B

Belite cement was prepared using nano-silicas extracted from three different agricultural wastes–black rice husk ash (BRHA), bagasse ash (BA), and palm oil fuel ash (POFA)–which were reacted at 1200 − 1400 °C with CaC2 residue as calcium sourc

A geopolymer prepared from dehydroxylated kaolinite-type clay was used as a host for trivalent rare earth ions to produce new photoluminescent materials. Sm3+ and Eu3+ ions were individually incorporated into the geopolymer host by ion exchange, part

The field of heterogeneous catalysis has recently become increasingly interested in the utilization of industrial wastes as inexpensive precursors for active catalysts. Here we report a facile synthesis of fly-ash-based geopolymers as new highly reac

Chemosynthetic aluminosilicate inorganic polymers exhibiting photoluminescent properties were prepared by introducing rare earth activator ions (Sm3+ or Eu3+) into the aluminosilicate structure by ion exchange. Under ~400 nm excitation, the materials
