A full factorial design and desirability function optimization method were performed to find the best UHPC ingredient proportions. To improve the concrete properties, the concrete performance in terms of CO2 em
Mix design Lightweight UHPC Lightweight materials Durability Structural efficiency 1. Introduction There are two contrary design concepts for concrete development, one is to increase the density of the matrix as high as possible aiming to attain better performance, and the other is to reduce the den...
Ultra-High-Performance Fiber-Reinforced Concrete(UHPFRC) Mixture design Preparation, mixing, casting, curing 1. Introduction UHPC is a high-strength, high-durability cementitious material. It has the potential to be a viable solution for improving the “sustainability of buildings and other infrastructur...

Ultra-high performance concrete (UHPC) has a very low water/cement ratio, high cement dosage and, when mixed with one or more of the available mineral admixtures (along with removal of any coarse aggregates), can generate a matrix with minimal internal pore space and optimal compactness, thus...
Ultra-high performance concrete (UHPC) is a new generation of high-performance concrete with extremely highstrength, ductility, and durability [1,2]. This type of concrete is generally considered to be characterized by acompressive strengthabove 150 MPa,fracture energyin the range of 1200–40000 ...
Ultra-high performance concrete (UHPC) integrates cutting-edge nano-additives, fibers and cementitious materials, which is a representative heterogeneous material and exhibits distinctive multi-scale structural characteristics. With remarkable durability and mechanical properties, lower embodied energy and diminis...
To achieve higher strength and better durability, ultra-high performance concrete (UHPC) typically employs a relatively small water-binder ratio. However, this generally leads to an undesired increase in the paste viscosity. In this study, the effects of liquid and powder polycarboxylate ...
Graphite tailings (GT) Ultra-high performance concrete (UHPC) Curing regimes Mechanical properties Microstructure 1. Introduction As economic progress continues, it has been a significant increase in the demand for mineral products, leading to the expansion of mining activities. This expansion has conseq...
Ultra-High-Performance Concrete (UHPC) is an advanced type of concrete in the Civil Engineering industry. It is a cement-based composite which exhibits improved mechanical and durable properties showing a high compressive strength of not less than 150 MPa and high tensile strength of not less than...
