Pervious high-calcium fly ash geopolymer concrete

Construction and Building Materials, 2012
Abstract This study evaluates the properties of pervious concrete made of high-calcium fly ash geopolymer binder. Pervious geopolymer concretes (PGCs) were prepared from lignite fly ash (FA), sodium silicate (NS), sodium hydroxide (NH) solution, and coarse aggregate.

FLY ASH -BASED GEOPOLYMERS: SYNTHESIS AND PROPERTIES

2007
Fly ash is the most important waste product of electricity production in coal-fired power station. It is being usually applied in cement and concrete industry, but the material has favourable properties for more valuable application, such as the conversion into the alkali – activated aluminosilicate materials, or "geopolymers"- a new ...

Strength development in clay–fly ash geopolymer

Construction and Building Materials, 2013
Abstract This paper presents the role of influential factors on the strength development in a clay–fly ash geopolymer that a silty clay is used as fine aggregates and fly ash, FA is used as a pozzolanic material. A liquid alkaline activator, L is a mixture of sodium silicate solution (Na2SiO3) and sodium hydroxide solution (NaOH).

Rheology of Fly-Ash-Based Geopolymer Concrete

ACI Materials Journal, 2011
There is limited literature available on the rheological behavior of slag-based geopolymer mortar and fly-ash-based geopolymer paste. This study will attempt to examine the rheological behavior of fly-ash-based geopolymer concrete with a mixture of sodium hydroxide and sodium silicate solutions.

Rheological Behavior of Fly-Ash-Based Geopolymers

2013
Geopolymers, a class of novel cementitious binders, have been gaining growing acceptance in commercial applications. One of the most important aspects for the commercialization of these products is their behavior in a plastic state. The workability of fresh geopolymer paste can be measured with several common tests, such as flow and slump; however, a ...

Fly Ash Based Geopolymer for Concrete Infrastructure

Under the assumed service scenarios, the addition of GO is beneficial not only for the environmental sustainability of FAGPR concrete-filled CFRP tube cylinders but also for their economic sustainability. The primary reason is that GO enhances the strength of the core concrete, reducing the need for CFRP tubes, which are costly and feature high Global ...
