alkali-activated concretecarbonationsteel corrosionThis study investigates the carbonation behaviour of alkali-activated fly ash-based (AFA) concretes. AFA contains 20.67% of unburned carbon. GBFS and OPC were used as sources of calcium (20%). A mixture of NaOH and Na2SiO3 was used as activator...
Ground granulated blast furnace slag with specific surface 380 m2/kg is commercially delivered by Kotouc Stramberk company and it is commonly used as an admixture in concrete production. It meets the requirements of EN 15167-1; for chemical composition see Table 1. In addition to the amorphous...
GGBFS and Red-Mud based Alkali-Activated Concrete Beams: Flexural, Shear and Pull-Out Test Behavior To accomplish environmental sustainability and reduce carbon emission, the construction industry needs to adopt waste industrial by-products as constructio... HM Al-Jabali,AA El-Latief,MS Ezz,......
In recent years, there has been growing interest in alternative cementitious materials that can provide enhanced performance and sustainability compared to traditional Portland cement-based concrete. Alkali-activated concrete (AAC) made of various industrial wastes has emerged as a promising alternative due...
Constitutive models representing the monotonic stress-strain response of rubberised alkali-activated concrete materials, as well as the unloading and reloading branches of the cyclic stress-strain response, are also given. Finally, formulations for the strain rate-dependent dynamic increase factors for ...

The first English-language book which reviews and summarizes worldwide research advances in alkali-activated cements and concrete. Essential topics include:- raw materials and their properties for the production of the two new types of binder- the hydration and microstructure development of alkali-activ...
The use of nonstandard aggregate and other industrial by-products, as well as the low costs of this type of concrete are also presented. Examples of applications of alkali-activated slag concrete of different composition are given. Some problems connected with the present use of alkali-activated ...
