Abstract: This research was carried out to evaluate the use of foundry sands on properties of flowable slurry. Two different flowable slurry mixtures were proportioned for strength levels in the 0.34–0.69 MPa (50–100 psi) range, at ...

Abstract: This study was carried out to evaluate the effect of foundry sand and fly ash on permeability of flowable slurry mixtures. In this work, two reference flowable fly ash slurry mixtures were proportioned for strength levels ...

Abstract: This research is conducted with a view to investigate performance of concrete containing high volumes of ASTM Class C fly ash. A portland cement concrete, proportioned to have 28‐day compressive strength of 6,000 psi (41 ...

Abstract: This investigation was performed to establish the effects of the source and amount of fly ash on abrasion resistance of concrete. A reference concrete was proportioned to have a 28-day age strength of 41 MPa. Three sources ...

Abstract: This project was conducted to evaluate the performance and leaching of controlled low strength materials (CLSM) incorporating fly ash and foundry sand. Two different CLSM (or flowable slurry) reference mixtures (equivalent ...

Abstract: Coal-burning powerplants generate about 72,000,000 t (80,000,000 ton) of combustion by-products per year in the United States. Each tonne (1.1 ton) of by-products used in lieu of portland cement in concrete saves about ...

Abstract: This investigation was performed to develop technology for manufacturing cast-concrete products using Class F fly ash, coal-combustion bottom ash, and used foundry sand. A total of 18 mixture proportions with and without ...

Abstract: This investigation was conducted to collect state-of-the-art information on the strength and durability of roller-compacted concrete (RCC) for pavement construction made with and without supplementary cementitious materials, ...
