The construction industry is responsible for a large amount of both embodied carbon and emissions. Especially with concrete, there still lot potential designing recipes in more ecological way. Approaches to reduce the environmental impact concrete include use industrial agricultural by-products. This study combines approaches replacing cement granulated blast furnace slag NaOH-treated rice stra...

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 ...

Abstract The present confront among the construction industry is to curtail production of ordinary Portland cement (OPC), which directly responsible emission harmful gases like CO 2 during manufacturing and also depletion natural resources lime stone, coal etc. investigation focused develop sustainable concrete using complementary cementing materials (CCMs) for environment. Ground granulated bl...

In this study, the early age thermal properties of a concrete mix containing ground granulated blast furnace slag (GGBFS) were investigated and incorporated in finite-element model. A two-term exponential degree hydration function was proposed to better capture behavior. An FEM program (ABAQUS) used predict temperature time-history three 1.2-m (4-ft) cubes cast with design 50% replacement cemen...

in this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. for this reason, various experimental parameters such as ph, contact time and the primary ion concentration were investigated. the remaining concentrations of ions such as; mn2+ and fe2+ in water were measured by atomic adsorption spectroscopy. the chemical and phase composition of slag, ...

At present, one of the most suitable ways to get a more sustainable cement industry is to reduce the CO₂ emissions generated during cement production. In order to reach that goal, the use of ground granulated blast-furnace slag as clinker replacement is becoming increasingly popular. Although the effects of this addition in the properties of cementitious materials are influenced by their harden...
