In recent years, UHP self-compacted concrete is an innovative category of concrete that has
attached a lot of attention because of its higher durability and compressive strength than conventional
concrete. So, to overcome the cost of preparation of UHPC and preservation of high-strength
deformation and rheological characteristic of self-compacting concrete when replacing a part of
expensive cement with three types of production waste. In addition, the problem of reducing
environmental pollution is solved. In this study. recycled glass (GP) and lime (LP) powder were
used as substitution materials in the manufacture of the UHPSCC. The flowability of UHPSCC was
measured by slump flow, T50, V-funnel tests as an indication for the capability of filling and J-ring
tests as an indication for the capability of passing. Furthermore, durability and mechanical properties
were investigated. The elevated temperature effect was investigated on several UHPCSCC samples
with glass (GP) and lime (LP) powder. The test results showed that the incorporation of GP and LP
partially replaced cement improved the flowability of UHPSCC. The compressive, tensile, and flexural
strength were enhanced by using GP till 20% replacement of cement also, the compression strength
values were highly improved by using LP replacement of cement at different ages for (hot and normal
curing). The highly compressive strength values for UHPSCC mixes with a 20% replacement ratio of
GP and LP as cement replacement materials were 119.0 and 128.8 MPa under hot curing regimes and
increased by 6.25% and 9.62%, respectively, than that of similar mixes under normal curing regimes at
90 days. The highly splitting and flexural strength values for UHPSCC 7 mix with 20% replacement
level of LP and UHPSCC 9 mix with 20% replacement level of LP and GP were reported at 11.80 and
17.85 MPa which increased by 24.20% and 58.60%, respectively, compared to the control mix. |
