The utilization of expanded polystyrene (EPS) beads in semi-lightweight concrete (SLC) intended for repair and building applications has gained great attention recent years. This study examines the effect mix design parameters including binder content, water-to-binder ratio (w/b), EPS silica fume (SF) additions on mechanical properties durability SLC mixtures. experimental program was carried o...

In India, most of the pavement is laid by bituminous road and the consumption of binder is high for pavement construction and also modified binders are used to satisfy any specific pavement requirement. Since the binders are visco-elastic material which is having the mechanical properties of binder transition from viscoelastic solid to visco-elastic fluid. In this paper, two different protocols...

SCGC (self-compacting geopolymer concrete) contains a new hybrid of self-compacting concrete and concrete, under the development in recent years, regarded to be an environmentally beneficial building material, as it does not use Portland cement traditional binder, its flowability eliminates need for vibrator application. Local pozzolanic materials containing silica (SiO2) alumina were utilized ...

This study investigates the effect of using Fume Silica (Aerosol 300) alone and together with crumb rubber (CR) in bitumen modification on traditional rheological properties binder compares it to SBS modified binder. Using aerosol additive at rates 0.5%, 1%, 1.5%, 2% were determined as most convenient ratio CR+aerosol binders prepared per this ratio. The subjected softening point, viscosity, fr...

In order to achieve a sustainable mix design, this paper evaluates self-consolidating green concrete (SCGC) properties by experimental tests and then examines the design parameters with an artificial intelligence technique. regard, cement was partially replaced in different contents granulated blast furnace slag (GBFS) powder, volcanic fly ash, micro-silica. Moreover, fresh hardened were perfor...

The use of date palm fiber (DPF) as natural in concrete and mortar continues to gain acceptability due its low-cost availability. However, the main disadvantage DPF cement-based composites is that it reduces compressive strength increases porosity composite. Hence, for be efficiently used concrete, negative effects must counteracted. Therefore, this study, silica fume was employed supplementary...
