摘要

PURPOSE: A finishing method of concrete floor is provided to strengthen concrete by alkali-aggregate reaction by supplying alkali ingredients inside the concrete. CONSTITUTION: A finishing method of concrete floor comprises: a step of removing foreign materials of the concrete floor; a step of inputting a crack repairing composition on a scratch on the floor and curing; a step of spraying a neutralization preventing composition on the concrete floor; a step of removing glass and curing; a step of spraying pigment on the concrete floor; and a step of spraying surface-layer coating composition on the concrete floor and curing.
