Abstract

This research studies the water absorption capacity of concrete panels and its self-healing process, using the incorporation of admixtures to the concrete or its application on the surface. Through permeability tests, water absorption by immersion and by capillarity, after the wet curing, the panels with crystalline admixtures applied superficially showed lower absorption capacity, followed by those without admixtures and those with the admixtures incorporated into the concrete, which showed greater absorption.  Microscopy characterization was performed on the panels split in half, it was observed that the crystallization of the panels with superficial admixtures was more advanced compared to those with the incorporated admixtures. The induced fissures did not reach full pore filling after curing in both types of application.
