In this study different mixtures of high strength concretes (70 MPa) were prepared with
different natures of aggregates, moisture content, length and dosage of polypropylene fibres …

Using a hydraulic servo pressure testing machine, we investigated physical and mechanical
properties of granite and sandstone samples after high-temperature treatment. Variations in …

混凝土材料因为性能优异, 取材广泛, 应用范围不断扩展. 火灾高温, 高纬度和极地严寒环境以及
液化天然气储罐等情形使得混凝土结构所承受的温度跨越1000℃ 左右的高温到-165℃ 的低温 …

This paper addresses the static properties and impact resistance of a “green” Ultra-High
Performance Hybrid Fibre Reinforced Concrete (UHPHFRC). The design of concrete …

Fire is a big risk to buildings and structures, posing a great threat to human lives. In this
study, a newly developed ultra-high performance concrete (UHPC) was investigated …

Long-term experiments were performed on red sandstones after different thermal treatments
(25, 300, 700 and 1000° C) under multi-step loading and unloading cycles and a confining …

In this paper, the Lattice Discrete Particle Model for fiber reinforced concrete (LDPM-F) is
calibrated and validated with reference to a new high-strength, ultra-high-performance …

Steel fiber reinforced concrete (SFRC) is composed of coarse aggregate particles, mortar
matrix, fibers, pores and microcracks from the viewpoint of meso-scale. To reflect the …

The influence of hybrid fibres on the response of self-compacting concrete to quasi-static
and high strain rates was laboratory investigated. The Split Hopkinson Pressure Bar …

This paper investigated mechanical properties of ultra-high performance concrete (UHPC)
after exposure to elevated temperatures ranging from 200° C to 800° C. Two casting …
