...Mohammed Gamal Al-Hagri; Mahmud Sami Döndüren A comparative evaluation of the single and combined effect of nanoparticles (NPs) on the static and impact properties of concrete is presented. Different NPs (silicon dioxide, aluminium oxide and ferric oxide) were used separately and in combination...

.... In relatively brittle materials like concrete, the deformation of the specimen is very small when subjected to impact loading; hence, it is very difficult to obtain the prerequisites of valid SHPB tests such as dynamic equilibrium and constant strain rate in the specimen. To overcome these issues, the current...

...Rowyda A. Zaki; Basem H. AbdelAleem; Assem A. A. Hassan; Bruce Colbourne This investigation aims to study the abrasion and impact resistance of fibre-reinforced concrete before and after exposure to salt scaling. Different types of steel fibre and different mixture compositions were used to improve...

...Wenjie Wang; Tongyue Zhang; Nawawi Chouw; Zhongxian Li; Zhaodong Xu Coconut fibre-reinforced concrete (CFRC) is widely used in the construction of house walls, especially in rural areas, but its impact resistance has rarely been studied. This paper investigates the dynamic compressive behaviour...

...Serhat Demirhan; Gürkan Yıldırım; Qais Sahib Banyhussan; Kemal Koca; Özgür Anıl; Recep Tuğrul Erdem; Mustafa Şahmaran The behaviour of concrete under sudden impact loads is complex. Moreover, very little is known about the impact behaviour of high-performance fibre-reinforced concretes (HPFRCs...

...Xiaohui Yu; Yao Xiao; Bing Li This study presents a procedure to evaluate the failure probabilities of reinforced-concrete (RC) slabs subjected to low-velocity impacts considering the uncertainties existing in slab features and impactor properties. A two-degree-of-freedom (2-DoF) non-linear model...

... and impact loads and reducing production costs. Static mechanical properties and repeated drop-weight impact tests of the designed hybrid-fibre-reinforced cementitious composites (HyFRCCs) are presented in this paper. The reinforcing effect of the new hybrid fibre system was found to be very close...

...Mohamed Ali Elsayed Mahmoud; Moncef L. Nehdi Extreme loading events such as blasts, impacts and earthquakes often lead to the partial or total collapse of reinforced-concrete structures, resulting in economic and human life losses. Civil engineers have therefore been seeking innovative materials...

...Yao Xiao; Bing Li; Kazunori Fujikake A two-degrees-of-freedom (2-DoF) dynamic model is proposed to predict the response of reinforced concrete (RC) slabs subjected to low-velocity impact. In this model, the slab stiffness is calculated based on its dynamic load–displacement curve, which is built...
