Nov 20, 2014· This book provides an updated stateoftheart review on new developments in alkaliactivation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet''s total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for .
(PDF) Life cycle assessment (LCA) of alkaliactivated cements and concretes | Claudiane OuelletPlamondon Life cycle assessment (LCA) is the best tool available to evaluate the environmental impact of alkaliactivated cements and concretes (AACC). However, recently published LCAs provide conflicting results.
There are shown studies on development of the alkaliactivated slag cements and concretes using Chinese raw materials. Such cements and concretes are able to provide high performance characteristics of materials and constructions under exposure of sea climate. The tests had been done for compliance with the requirements set in the national standards of and were determined ...
concretes based on alkaliactivated binders, there is limited existing knowledge about the longterm inservice stability of these materials, although the studies that have been published show generally moderate to low carbonation rates ( mm/year), similar to the carbonation rate of Portland cement concretes [5]. In this
Life cycle assessment (LCA) is the best tool available to evaluate the environmental impact of alkaliactivated cements and concretes (AACC). However, recently published LCAs provide conflicting results. We propose a new way to compare AACC with

Firstly, alkali activated cement is a broad class of material and geopolymer is one of those cements. Since you are using lowcalcium fly ash which essentially means that content of silicon and...
specifications for alkali activated cements and concretes is ongoing in many parts of the world, including in the UK where the worldfirst British Standards Institute (BSI) Publicly Available Specification PAS8820:2016 has been published to describe these materials and their utilisation. However, the technical rigour, and thus
The relationship between flexural and compressive strength of the concretes assessed is higher than the recommendation of ACI 31808 and the Australian standard AS3600 (Bernal et al. 2012e), suggesting that adopting design criteria used for Portland cementbased concretes when using alkaliactivated slag concrete leads to a conservative design ...
