چکیده
The present study focused on developing Alkali Activated Fine Aggregate (AAFA) by palletization method. AAFA was manufactured using Ground Granulated Blast Furnace Slag (GGBS) and alkali activator solution at ambient conditions. Sodium hydroxide of six molarity sodium silicate to ratio 2.5 used. AACA's properties are similar Natural except for flakiness elongation index. water absorption Abrasion value have high AACA compared natural aggregate. slump is an increase in replacement level up 40% aggregate further there decrees a slump. Compressive, Split, Flexural strength has shown noticeable all levels However, beyond the 40 % level, decrease strength. It may be attributed reduced bond between paste

Mechanical Properties and Eco-Efficiency of Steel Fiber Reinforced Alkali-Activated Slag Concrete
Conventional concrete production that uses ordinary Portland cement (OPC) as a binder seems unsustainable due to its high energy consumption, natural resource exhaustion and huge carbon dioxide (CO₂) emissions. To transform the conventional process of concrete production to a more sustainable process, the replacement of high energy-consumptive PC with new binders such as fly ash and alkali-acti...
متن کاملSELF-Cured Alkali Activated Slag Concrete Mixes- An Experimental Study
Alkali Activated Slag Concrete (AASC) mixes are manufactured by activating ground granulated blast furnace slag (GGBFS) using sodium hydroxide and sodium silicate solutions. The aim of the present experimental research was to investigate the effect of increasing the dosages of sodium oxide (Na2O, in the range of 4 to 8%) and the activator modulus (Ms) (i.e. the SiO2/Na2O ratio, in the range of ...

In order to study the basic mechanical properties of basalt fiber reinforced recycled aggregate concrete, the concrete mix ratio, the length and the volume mixing ratio of chopped basalt fiber yarn are designed for changing factors. A total of 324 specimens have been completed for this investigation. The compressive strength, splitting tensile strength, elastic modulus and axial compressive str...
متن کاملmechanical and durability properties of slag based recycled aggregate concrete
in this paper, the possibility of using recycled aggregate (ra) and ground granulated blast furnace slag (ggbfs) to produce a structural concrete was studied by compromising strength to a lesser extent. hence an attempt has been made to study the strength and durability characteristics of the ggbfs-based recycled aggregate concrete. four different groups of mixes were designed by replacing natu...
