•Blast resistance of BFRP reinforced sea-sand seawater concrete slab was investigated.•Damage modes of BFRP reinforced sea-sand seawater concrete slab under explosion were revealed.•Sea-sand seawater concrete slab has comparable blast resistance with usual concrete slab.•An equivalent static load method for BFRP reinforced sea-sand seawater concrete slab was developed.
Avoiding steel corrosion in seawater sea-sand concrete (SSC) members, basalt fiber reinforced plastic (BFRP) bars behaving as reinforcement have advantages in coastal civil engineering and protective structures. One-way BFRP-bar reinforced SSC slabs (BRSSs) were designed to investigate their mechanical responses under static loads and close-in explosions. The SSC blocks have comparable quasi-static compressive strength with plain concrete blocks. The BRSSs have comparable quasi-static flexural strength and identical failure mode with the BFRP bars reinforced plain-concrete slabs (BRPSs). Under close-in explosions, the BRSSs have comparable blast resistance and similar failure modes with the BRPSs. Together with the excellent anti-corrosion ability, the BRSS is an ideal selection for costal protective structures.
