In this paper, we present an experimental study and statistical modeling of High-Performance Concrete subjected to high temperatures. The main objective of this study is to examine the effect of concrete age subjected to high temperature cycles (ranging f... see more

Due to the high aggressiveness in which the concrete structures are exposed, many researches have been developed in this area and search for materials with superior mechanical performance and durability has been the target of the researchers of concrete t... see more

The objective of this paper is to investigate the bond properties of prestressing strands embedded in Ultra–High–Performance Concrete (UHPC).The UHPC was made in laboratory using local materials in Vietnam.Its mixture contains: silica aggregates, portland... see more

Most of the structures that are damaged by an explosion are not initially designed to resist this kind of load. In the overall structure of any building, columns play an important role to prevent the collapse of frame structure under blast impact. Hence, ... see more

This paper reports the results of an experimental study on the high performance concrete made with copper slag as fine aggregate. The percentage of Copper Slag(CS) added by weight in a range viz. 0, 25, 50, 75 and 100% as a replacement of sand used in con... see more

Experimental studies play a crucial role in shedding light on the dynamic behaviour of structures under blast loading. However, high costs and complicated technical requirements, particularly for full-scale structures, are still huge disadvantages to cond... see more

This article evaluated mechanical behavior of ultra-high performance concrete (UHPC) reinforced with hybrid steel and polypropylene fibers, with cement consumption of 250 kg/m³ and application of confining pressure in fresh state. The consistency of the m... see more

Two different high performance lightweight concretes (HPLC) with strengths of 55 and 69 MPa were developed. They had an air-dry unit weight of 1855 and 1890 kg/m³, respectively. Creep, shrinkage and prestress losses were investigated on 36 cylinder specim... see more
