Study on Mechanical Properties and Durability of Alkali-Activated Silicomanganese Slag Concrete (AASSC)

PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

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...

mechanical 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...

SELF-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 ...

Effects of alkali addition on the mechanical properties and durability of concrete

Increasing the concrete alkali content from 0.6% to 1.25% of Na2Oe of the cement mass by adding NaOH to the mixture water has harmful effects on most mechanical properties (compressive, splitting, direct tensile, and flexure strengths) of concrete made with a water-tocement (w/c) ratio of 0.41 and limestone aggregates not susceptible to alkali–silica reaction (ASR), however not on the elasticit...
