Morphology
over-burned + lime
The phrase is transparently compositional: 'over-burned' can be parsed as 'burned excessively/too much' and 'lime' is a known building material, so the combined meaning 'lime that has been burned too much (losing reactivity)' is directly inferable. This follows regular English derivation and compounding patterns, so a B1 learner who knows the constituents would likely understand it.
Etymology
Over-burned lime comes from making lime in a hot oven called a kiln. If the lime is heated too long or too hot, the burned part is overdone and the lime becomes hard and stops reacting with water, so it will not hold mortar together.
