Abstract In recent years the word sustainability has become a priority of many researchers. this regard, evolutions were put forth in concrete industry one them is Geopolymer concrete. Ground granulated blast furnace slag (GGBS) used as source material which rich alumina and silica contents, forms silicate gel when mixed with an alkali solution sodium hydroxide then binds aggregate. Till now re...

The present study compares conventional pavement and perpetual in the case of ground-granulated blast-slag-stabilized black cotton soil. Ground-granulated blast slag (GGBS) can be used for over weak subgrade. We added to soil proportions 10 %, 20 30 40 %. After determining engineering properties GGBS, modified Proctor compaction California bearing ratio tests were performed. these values, six c...

This paper studied the influence of modulus and dosage sodium silicate on hydration alkali-activated copper-nickel slag (CNS) materials. CNS was used as main raw material, ground granulated blast furnace (GBFS) powder selected mineral additive. The hardening mechanisms were discussed. experimental results showed that [SiO4]4− [AlO4]5− with a high degree polymerization in glassy phase more easil...

Abstract An attempt to shed light on the use of agro-industrial-based wastes as supplementary cementitious material (SCM) or alkali-activated binder (AAB) is mainly focused in this review paper. The SCM AAB acts a suitable replacement for cement, cement manufacturing tends contribute 8–10% global CO 2 emissions. To gain acceptability construction industry, diverse must demonstrate their potenti...

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...
