“…The detonation of solid explosives may give rise shock wave under pressure up to 30000 MPa and temperatures about 3000-40000C [14]. The types of secondary solid explosives that is trinitrotoluene (TNT) [24][25][26] and ammonium nitrate/ fuel oil (ANFO) [11] mostly used in concrete blast events.…”

“…The mass of explosive is directly proportional to standoff distance. There are a research that performed a blast test with 0.51kg mass of TNT with 400mm standoff distance, 34kg and 1675mm [11], respectively. Some researcher also conducted an experiment that evaluate the level of performance of reinforce concrete slab by varying the explosive weight and standoff distance [29].…”

Abstract. The severe damage to civilian buildings, public area, jet aircraft impact and defense target under explosive blast loading can cause a huge property loss. Most of researcher discusses the topics on design the concrete material model to sustain againts the explosive detonation. The implementation of modern reinforcement steels and fibres in ordinary Portland cement (OPC) concrete matrix can reduce the extreme loading effects. However, most researchers have proved that geopolymer concrete (GPC) has better mechanical properties towards high performance concrete, compared to OPC. GPC has the high early compressive strength and high ability to resist the thermal energy from explosive detonation. In addition, OPC production is less environmental friendly than geopolymer cement. Geopolymer used can lead to environmental protection besides being improved in mechanical properties. Thus, this paper highlighted on an experimental, numerical and the analytical studies cause of the explosive detonation impact to concrete structures.

“…By the addition of steel fibres to the conventional concrete, the impact strength value has increased 2-15 times depending on the amount of the fibres [1]. Better performance of fibre reinforced concrete (FRC) under impact load compared to plain concrete without reinforcement was also confirmed by [2][3][4]. Maalej et al [5] found that hybrid fibre-reinforced concrete (using combinations of two or more types of fibres in the same concrete mixture) offered increased shatter resistance with reduced scabbing, spalling and fragmentation, whilst exhibiting better energy absorption.…”

Abstract. The paper summarizes the results of the development of special concrete intended for the explosion resistance applications, with the emphasis on minimal secondary fragments formation at the explosion. The fine-grained concrete matrix has been reinforced by various types of short dispersed fibers (metallic, mineral and polymer) of different sizes and by their combination and the effect of the fibre reinforcement on the physico-mechanical properties and blast resistance was observed. The concrete prism specimens have been subjected to the determination of mechanical parameters (compressive and flexural strength at quasi-static load). The blast tests were conducted on the slab specimens prepared from selected mixtures. The material characteristics and explosion test data have been used for numerical investigation, which defined the optimal wall composition and dimensions of the concrete element which should resist the explosion defined by type, size, weight and placement of the blast. In the next step the test elements resistance was verified by real explosion test.
