Steel fiber is widely used to improve the flexural performance of ultra-high concrete (UHPC), yet synergistic effect steel and coarse aggregates in UHPC containing (UHPC-CA) has not been elucidated. Here, influence content on rate-dependent UHPC-CA investigated from view aggregates. Results reveal that increasing pull-out force due increase crack mouth opening speed at a higher loading rate res...

The inferior mechanical properties and durability of conventional lightweight concrete restrict its wider application. This study intended to design a novel ultra high-performance (L-UHPC) using mathematical approach, with view achieving low density excellent performance. Two materials (i.e. micro-sized glass microsphere expanded shale aggregates) were introduced in the mix L-UHPC. statistical ...

Ultra-high performance concrete (UHPC) exhibits superior mechanical and durability with very high compressive strength. Compared ordinary concrete, it is more environmentally friendly has the great potential to be a practical solution improve sustainability of infrastructure. This study focuses on examining thermal properties UHPC coarse aggregates (CA-UHPC) subjected temperature ranged from 20...

This study aims to evaluate the environmental impacts of off-site construction using ultra-high-performance concrete (UHPC) and different curing methods. Life cycle assessment (LCA) is implemented proposed UHPC traditional (TC) under conditions from cradle gate. Unlike previous studies that considered function unit as 1 m3, this investigates elements with same load capacity. Comparison made bet...

This study aims to produce Ultra-High-Performance Concrete utilizing locally available material. The experimental includes silica fume with rice husk ash in combination steel fibers. Various trials were made using different volumes of local materials and fibers UHPC. Different properties evaluated, such as compressive strength, tensile Scanning Electron Microscopy (SEM). Results show that UHPC ...

With the aim to reduce environmental footprint of buildings, this paper presents an original structural system concept for two-way slabs in residential and office buildings. The proposed extends best practice terms modularity, versatility, demountability, reusability, durability. A finite set elements can be used form main load-bearing multiple successively constructed buildings having differen...

The reinforcement of ultra-high-performance concrete (UHPC) with fibers was investigated in this study. Concrete is the most widely used manmade construction material, and UHPC has remarkable mechanical properties. properties can be modified by a variety curing procedures amount cement used. This study aimed to examine impact fiber reinforcement, temperature, exposure time on UHPC. Initially, t...

Ultra-High Performance Concrete (UHPC) proved to be very durable in harsh environments, primarily because of the extremely low porosity matrix (uncracked). However, limited availability design standards is still a barrier widespread applications UHPC, together with knowledge its durability real (cracked) service conditions. In this paper, use tailored UHPC introduced, whose composition has been...

Ultra-High Performance Concrete (UHPC) is a cementitious composite with fine aggregates and homogeneous matrix high compressive strength excellent durability against aggressive agents. It common to use short steel fibers in the UHPC. Besides, using considerably increases flexural ductility, energy absorption. Using glass UHPC novel technique which improves its mechanical properties it has benef...
