Narrative:

Mfd VFR day; light traffic; very light complexity. Runway 32 closed with men and equipment on runway 32. No runway closure signs were placed on runway 32 by airport management. Runway 14/32 closed was recorded and broadcasting on the ATIS. The mandatory runway 14/32 closed placard was placed in the local control podium.I was on local control training a developmental. Aircraft X was inbound from the southwest of mfd. Mfd approach coordinated a departure corridor inbound and it was approved. Aircraft X was instructed to enter left downwind runway 23 on initial contact with the tower. As aircraft X was tracking inbound; he appeared to not be complying with the instruction and the trainee issued a suggested heading of 060 vectors left downwind runway 23. Aircraft X was informed of traffic departing runway 23 and aircraft X appeared to gain bearing of position and began a turn for a left downwind runway 23. Aircraft X was instructed to resume pilot own navigation and enter left downwind runway 23. As the trainee and I continued our scan of the airport and other traffic; we scanned back to aircraft X and aircraft X appeared to be on a left downwind for runway 23. The trainee then cleared aircraft X for the option runway 23. Aircraft X read back cleared for the option runway 23. The trainee and i continued our scan towards the other areas of the airport. We both returned our attention to scan aircraft X and aircraft X was touching down on runway 32. The trainee then instructed aircraft X to abort and climb up immediately men and equipment on the runway. Aircraft X began to go around immediately after that.a mandatory requirement for runway closure signs to be placed on runways that are NOTAM closed by airport management.
