Floor repairs after wall removed by previous owners

[TonyS82]

Hi all, looking for some advice again.
The previous owners removed an internal wall and after lifting the lamjnate flooring i have exposed a cracked and loose scar of concrete where the wall would have stood. Just wondered what my options are.

The floor is a suspended timber floor on honeycomb walls and the joists run perpendicular to the scar. From the images it looks like some shuttering was put either side of the scar and concrete poured in level with the floorboards. Not sure if this is from original build or when the wall was taken out.
The floor joists do not line up either side of the scar.
Is it safe to break up and remove the concrete and span the gap between the honeycomb walls either side and lay a new floorboard over the gap? Seems a lot of work for just one length of floorboard. Or is it best to remove and pour new concrete into the gap?

Thanks
Tony

What are your plans for flooring on top, are you going to install laminate again?

If so probably just go straight over it again as previously.

I presume there is a reason they didn't fit a floor board there in the first instance likely because it would have been very time consuming

we are planning to narrow the opening by installing a short stud wall either side off of the remaining brickwork and install bifolds or french doors and then laminate flooring all the way through. it is very noisy when walked on and does move under foot.
