Geopolymer cements provide an alternative to the Portland cement used to manufacture structural concrete. The material commonly used to produce geopolymers is fly ash, w[...]

Historically, concrete strength has been one of the primary properties specified to ensure concrete quality. As the construction industry advances, owners and major stake[...]

Geopolymer cement is an alternative binder manufactured from fly ashes that can fully replace portland cement in traditional reinforced concrete applications. As a viable[...]

Supplementary cementitious materials (SCMs) provide a variety of benefits to fresh and hardened concrete. These materials can be found in naturally occurring substances o[...]

The suitability of fly ash based geopolymer concrete as a replacement for ordinary Portland cement (OPC) concrete depends on the mobility of elements from the material. D[...]

The coal-fired steam electricity plants are interested in finding efficient ways to manageby-products from the combustion process out of environmental and regulatory cons[...]

In 2014 approximately 47% of the 190 million short tons of coal combustion product (CCP) was recycled. As a construction material, coal fly ash (CFA) finds considerable u[...]

Organo-silane (OS) surface modification works by chemically altering the surface of silica based materials and rendering them hydrophobic (waterproof). Limited research [...]

Geopolymers can be categorized as synthetic zeolitic monoliths. The amorphous structure of this material is developed by dissolution of an aluminate and silicate-rich sou[...]
