dc.description.abstractThis study examined the effects of herbicides on stone and masonry materials. Although the ecological effects of herbicides are well studied, it is unclear how herbicides affect the stone and masonry material that they contact. This experiment tested Roundup® and Garlon®4, on brick, limestone, concrete, and granite. After exposure to the herbicides, the stone and masonry samples were placed in a QUV to undergo artificial weathering. The samples were monitored periodically for physical and chemical changes by measuring these parameters weight and pH, and using the following tests: colorimetry, Fouier transform infrared spectroscopy, absorption, and X-ray defraction. The results showed that these herbicides negatively affected the materials in the following ways: salt formation and color change. While Garlon®4 changes the aesthetics of the material, Roundup®can lead to a long-term, increased rate of deterioration.
