Ultra-high performance concrete (UHPC) is renowned for its exceptional strength, durability, and structural integrity, offering sustainable solutions construction. However, concerns persist regarding long-term under various environments due to unhydrated cementitious particles. This study investigates the effect of steel fiber content on stability UHPC in tap water, outdoor, seawater over 720 days. Results show that adding 1%~3% increases compressive strength by 4.5%~11.5%, 9.5%~18.5%,...
Ultra-high-performance concrete (UHPC) is an advanced material known for its high strength and durability. This study investigates the long-term stability of slag-containing UHPC exposed to outdoor, tap water, seawater environments over 720 days, focusing on impact steel fiber content. The results show that in water exhibits higher compressive compared outdoor environments. Without fibers, strengths at 1 day, 28 days are 99.7 MPa, 104.7 148.0 respectively. With 3% fiber, these values...
The adsorption behaviour and dispersing capability of structurally different polycarboxylate superplasticisers (PCEs), with various carboxylic densities, was investigated in the presence sulfates. effect sulfates on early cement hydration evolution PCEs densities also analysed. It found that a higher proportion carboxylate groups PCE backbone contributed to more intense onto grains, which lower sensitivity competitive sulfate ions hence produced resistance negative impacts fluidity zeta...
In this study, by adding a small amount of calcined desulfurization gypsum and aluminate cement into slag powder cement, the effects on flowability, mechanical properties volume stability composite cementitious system were studied. The results show that can be improved appropriate cement. For example, when ratio sulfur to aluminum is 0.5:1, compressive strengths gypsum-aluminate cement-slag increases 34% in 1 day, 8% 180 days, free expansion rates are less than 0.6%, stresses tensile...
