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.
Highlights
Geopolymer is an alternative material as to replace the used of ordinary Portland cement (OPC)
Velocity of detonation (VOD) and density of explosives was differed through their physical state as solids, liquids or gases [23]
The commercial explosive been used in blast experiment, the velocity of detonation is fewer than TNT and ammonium nitrate/ fuel oil (ANFO)
Summary
Geopolymer is an alternative material as to replace the used of ordinary Portland cement (OPC). Geopolymer concrete is widely used in constructing buildings namely as beam, slab, girder, column and wall. These main structures must be mechanically design to withstand high loads and external impact. An explosive detonation was conducted on air blast, blast in confined space [15] and, direct contact with blast load [9, 16]. Blast in confined space will trigger more energy concentration while the pressure behavior in air blast is low frequency blast vibration. The extreme energy from detonation can create impulsive impact and in consequence, many researchers proposed the high strength of the concrete structures [12,13,14,15, 26].
