Abstract
Concrete is one of the most utilized building materials and the source of some of the world’s most serious environmental and sustainability problems. Instead, waste glass (WG) as recycled material is used. There
is a lack of experimental studies of reinforced concrete (RC) beams containing WG. This research focuses
on the flexural behavior of RC beams containing glass powder (GP) as a replacement for cement, and
beams containing glass fine (GF) as a replacement fine aggregate. The experimental program comprises
10 tested beams designated as control beam, beams with cement replacement by GP with values of 10% and 20%, and beams with fine aggregate replacement by GF with values of 10% and 15%. The effect of
the longitudinal steel ratio is also included in the program. The experimental results included slump test,
compressive and tensile strength tests, crack patterns, load-deflection, and load-strain relationships for RC
beams.
In the published paper in Construction and Building Materials- Elsevier, ten concrete beams were tested to investigate the flexural performance of concrete beams adding glass as a replacement for cement and fine aggregate. The variables were the amount of glass added to the concrete mixture as an alternative to
cement and fine aggregate, and the ratio of reinforcement. results of the slump tests showed close results
for the slump, setting time, and compressive and tensile strengths for the mixes containing WG when
compared to the control mix. On the structural level, beams containing 10% GP as an alternative to cement
showed an increase in the cracking and ultimate loads respectively by 29.0% and 6.9%, and beams containing 20% GP as an alternative to cement showed insignificant reductions in the cracking and
ultimate load. and with an increase in the reinforcement percentage showed an increase in the cracking
and ultimate loads respectively by 8.0% and 39.0%, and the beams containing 10% GF as an alternative to fine aggregates showed a slight increase in cracking and ultimate load, respectively by 10.0% and 0.6%.The beams containing 15% GF as an alternative to fine aggregate showed insignificant reductions in the
cracking and ultimate load, and with an increase in the reinforcement percentage, the results showed an increase in the cracking and ultimate load, respectively by 42.7% and 22.7%.
