Hydrated lime is a historic material currently used in conservation. It hardens slowly by carbonation slowing construction however, supplementary cementitious materials accelerate hardening enhancing strength. Hydrated-lime mortars with rice husk ash–RHA-; ground granulated blastfurnace slag–GGBSand increasing amounts of two aggregates were studied. Increasing aggregate lowered strength as inte...

Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage o...

Abstract—In this study, the Compressive strength of concretes made with Ground Granulated Blast furnace Slag (GGBS), Pulverised Fuel Ash (PFA), Rice Husk Ash (RHA) and Waste Glass Powder (WGP) after they were exposed 780C (exposure duration of around 60 minutes) and then allowed to cool down gradually in the furnace for about 280 minutes at water binder ratio of 0.50 was investigated. GGBS, PFA...

The treatment of sulfate-bearing soil with calcium-based stabilizers such as cement or lime often results in ettringite formation, consequently leading to swelling and strength deterioration. Ettringite formation has negative environmental economic effects on various civil engineering structures. This study was conducted investigate the use different materials (nano–magnesium oxide (M), ground ...

Hydrated lime (Ca(OH)2)- and reactive magnesia (MgO)-activated ground granulated blast-furnace slag (GGBS) have shown advantages in geotechnical applications compared with Portland cement (PC). To apply these two novel binders slurry form to field applications, the properties of their grouts need be investigated, which is objective this study. The heat hydration, bleeding, viscosity, setting be...

In this study, Geopolymer concrete (GPC) blended with fly ash (FA), ground granulated blast furnace slag (GGBS), rice husk (RHA), and nano-silica (NS) developed investigated in three aspects: the first aspect of GPC (FA+GGBS), FA varied from 0-100% GGBS at 10 % intervals to determine optimum proportion FA-GGBS. second (FA+GGBS+RHA), RHA 0-25% 5% a constant 30% attained study. third (FA+GGBS+RHA...

The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

In this study, the effect of glass powder (GP) and ground granulated blast furnace slag (GGBS) on the compressive strength of Fly ash based geopolymer concrete has been investigated. The mass ratio of fine aggregate (fA) to coarse aggregate (CA) was maintained constant. NaOH flakes dissolved in water was used as activating liquid and mixed with fly ash (FA) to produce geopolymer paste or cement...

Abstract The Ordinary Portland Cement (OPC) is one of the major ingredient utilized for manufacture concrete. manufacturing cement includes release huge amounts CO 2 gas as a main contributor greenhouse influence and global warming. Several researchers have investigated characteristics OPC concrete utilizing cementitious materials like fly ash, silica fume, Ground Granulated Blast furnace Slag ...
