Title: MICROSTRUCTURE AND STRENGTH OF THE BOND BETWEEN CONCRETE AND STYRENE - BUTADIENE LATEX-MODIFIED MORTAR
Accession Number: 00214096
Record Type: Component
Abstract: VARIOUS TECHNIQUES FOR THE PREPARATION OF THE CONCRETE SUBSTRATE SURFACE AND FOR THE APPLICATION OF THE LATEX- MODIFIED MORTAR TO THIS SUBSTRATE WERE STUDIED. A 1-IN. MORTAR CAP WAS APPLIED TO THE CIRCULAR SURFACE OF 14-DAY OLD, HIGH EARLY STRENGTH CONCRETE CYLINDERS TREATED IN VARIOUS WAYS. AFTER AGING 14 DAYS, SEVERAL CYLINDERS OF EACH GROUP WERE FRACTURED IN A SHEAR BOND TEST, AND AN UNFRACTURED CYLINDER WAS SAWED TO PROVIDE A 1/2-IN. CUBE THAT INCLUDED THE INTERFACE BETWEEN CONCRETE AND MORTAR. THESE CUBES WERE FRACTURED NORMAL TO THE INTERFACE, PRODUCING A SURFACE FREE OF SAWING ARTIFACTS. AFTER THEY WERE EXAMINED IN THE SCANNING ELECTRON MICROSCOPE, THESE SECTIONS WERE FRACTURED AGAIN TO SIMULATE THE SHEAR BOND TEST AND THEN REEXAMINED. SEVERAL PERFORMANCE VARIATIONS ARE EXPLAINED BY THE SCANNING ELECTRON PHOTOGRAPHS. /AUTHOR/
