Properties of the Mortar Modified with the Styrene-Acrylic Emulsion
Styrene-acrylic emulsion was selected to modify the cement mortar which was prepared as the crack mending material for the concrete pavement. The results indicated when the percentage of the styrene-acrylic emulsion was from 15% to 20%, the flexural strength and the bent bond strength increased by 39.00%~48.23% and 45.01%~49.60% respectively at 28 days, compared to the reference mortar. The morphology of the cement mortar modified with styrene-acrylic emulsion was observed by SEM. The modification mechanism of the styrene-acrylic emulsion to the mortar was discussed.
