Influence of Amount of Recycled Coarse Aggregates and Production Process on Properties of Recycled Aggregate Concrete
TL;DR: In this paper, four different recycled aggregate concretes were produced; made with 0, 25, 50, 50 and 100% of recycled coarse aggregates, respectively, in order to achieve the same compressive strengths.

Effect of GGBFS on setting, workability and early strength properties of fly ash geopolymer concrete cured in ambient condition
Pradip Nath,Prabir Kumar Sarker +1 more
TL;DR: In this paper, a fly ash-based geopolymer concrete for curing in ambient condition can be proportioned for desirable workability, setting time, and compressive strength using ground granulated blast-furnace slag (GGBFS) as a small part of the binder.
Journal ArticleDOI
Study on the influence of attached mortar content on the properties of recycled concrete aggregate
TL;DR: In this article, the authors analyzed data from experimental works carried out in CEDEX and also from literature review to obtain experimental relationships between the attached mortar content and other recycled aggregate properties, covering a wide range of different aggregates qualities.

NaOH-activated ground fly ash geopolymer cured at ambient temperature
Kiatsuda Somna,Chai Jaturapitakkul,Puangrat Kajitvichyanukul,Puangrat Kajitvichyanukul,Prinya Chindaprasirt +4 more
TL;DR: In this paper, ground fly ash (GFA), with a median particle size of 10.5μm, was used as source material for making geopolymers cured at room temperature, and compressive strength tests and microstructure observations using SEM, EDX, XRD and FTIR were performed.

Workability and strength of coarse high calcium fly ash geopolymer
TL;DR: In this article, the basic properties viz., workability and strength of geopolymer mortar made from coarse lignite high calcium fly ash were investigated, and the results revealed that the workable flow of the geopolymers was in the range of 110 −±5% −135 −± 5% and was dependent on the ratio by mass of sodium silicate to NaOH and the concentration of NaOH.
