Abstract
|
|
|
|
| The present invention relates to the field of ultra-high performance concrete with reduced Portland cement content where Portland cement is partially substituted with borosilicate glass lamp waste powder. Borosilicate glass lamp waste powder is obtained from borosilicate glass lamp waste chips, which are received from a recycling company. The concrete composition comprises, wt.%: CEM 1-type Portland cement - 22.4-25.3 with a minimum compressive strength of 52.5 MPa after 28 days; borosilicate glass lamp waste powder as cement substitute - 3.9-5.9; fine aggregates (sand) - 46.5-49.6; steel fibers - 2.0-2.1; fillers (quartz powder, silica fume and nano-silica) 14.4-15.1; a polycarboxylate-based superplasticising additive - 1.1-1.2; and water - 5.7-5.9. |
