cumulative, accumulative
are both used in the meaning ‘formed or increasing by successive additions’, although cumulative is now more usual (as in cumulative arguments, effect, evidence, force, etc.). Accumulative is however still found, (there are around 100 examples in the OEC) and by virtue of its form has stronger associations with the process of accumulating:
