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.
