ABSTRACT

This paper presents the results of an experimental study on the possible use of rejected fly ash (rFA), furnace bottom ash (FBA), and lightweight aggregates (LWA) to produce lightweight self-compacting concrete (LSCC). It was found that https://www.w3.org/1998/Math/MathML"> r https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq12196.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> -FA was able to replace viscosity modifying agents to control the segregation resistance of LSCC. The oven-dried density of the LSCC could be further reduced when the sand was replaced by FBA. Based on the experimental results, LSCC can be produced by using https://www.w3.org/1998/Math/MathML"> 150   k g / m 3 r - F A https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq12197.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> as powder, and https://www.w3.org/1998/Math/MathML"> 30 - 50 % https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq12198.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> FBA to replace sand. The LSCC has good fresh and hardened properties, and durability properties.
