Bending Toughness and Calculation Model of Ultrahigh-Performance Concrete with Hybrid Micro- and Nanofillers
Publisher: ASCE
Abstract: Superfine stainless wires (SSWs) and carbon nanotubes (CNTs)/nano SiO2-coated TiO2 (NTs) were used as hybrid micro- and nanofillers to toughen reactive powder concrete (RPC) in this paper. The multiscale synergistic ...
Stainless Steel Wires-Modified Asphalt Concrete for Self-Heating and Self-Deicing
Publisher: American Society of Civil Engineers
Abstract: Stainless steel wires (SSWs)-modified asphalt concrete with stable long-term properties and high electrical conductivity as well as without puncturing vehicle tires is expected to become a promising multifunctional pavement ...
Principle and Implementation of Incorporating Nanomaterials to Develop Ultrahigh-Performance Concrete with Low Content of Steel Fibers
Publisher: American Society of Civil Engineers
Abstract: The effect of nanomaterials on the microstructure of ultrahigh-performance concrete (UHPC) has been intensively studied, but the relationships between the macroscopic flexural failure process and microstructures of ...
Developing a Sustainable Ultrahigh-Performance Concrete Using Seawater and Sea Sand in Combination with Superfine Stainless Wires
Publisher: ASCE
Abstract: Utilizing seawater and sea-sand for producing ultra-high performance concrete (UHPC) can substantially reduce raw materials costs and alleviate the current freshwater and river sand resources shortage in coastal and marine ...
Electromagnetic Wave-Absorbing Property and Mechanism of Cementitious Composites with Different Types of Nano Titanium Dioxide
Publisher: ASCE
Abstract: Ten types of nano TiO2 (NT) were used to endow cementitious composites with the electromagnetic absorbing property. The influences caused by sample thickness, the size, and surface treatment of NT on the electromagnetic ...
Enhanced Impact Properties of Concrete Modified with Nanofiller Inclusions
Publisher: American Society of Civil Engineers
Abstract: This paper investigated the impact properties of reactive powder concrete modified with different types (nano-SiO2, nano-TiO2, and nano-ZrO2) and dosages (1.0% and 3.0%) of nanofillers. Three mechanical parameters (dynamic ...
