Abstract

In order to complement the disadvantages of the concrete surface treatment technology and improve the durability performance of concrete, the penetration of water-repellent impregnated natural zeolite is introduced to the cement mortar for chloride penetration resistance. An experimental study on the effects on performance and microstructure was advanced. It can be confirmed that the water absorption and the permeation resistance performance of the test specimen containing ZWR are improved in proportion to the mixing amount. It was also confirmed that the permeation resistance performance of chloride was smaller than that of OPC in terms of total passing charge. In addition, it was confirmed that the hydration reaction was sustained for a long time in the pojollan reaction of natural zeolite, and no difference in crystal phase or structural change was observed with the reference mortar in the XRD test results.
