Effects of Kcc-1/Ag Nanoparticles on the Mechanical Properties of Concrete

The effect of nano kcc-1/ag and nano sio2 in concrete have been investigated in this study. nano kcc-1/ag and nano sio2 are synthesized and their characterization was investigated by ftir, sem, and tem analysis. after that, these materials use as cement replacement in 1, 2, and 3 percent amounts. sem images illustrate the denser structure of kcc-1/ag nanoparticles. furthermore, in the ftir spectra 3640 cm^-1 is related to c-s-h, which is sharper and more severe in samples with nano kcc-1/ag and nano sio2. the results revealed that nano sio2 and nano kcc-1/ag both improved the microstructure of cement paste and increased the concrete compressive and splitting tensile strength. for comparison the performance of nano kcc-1/ag and nano sio2, the results indicated that nano kcc-1/ag improved the microstructure of concrete better than nano sio2. hence, it has a better performance in enhancing the strength of concrete. the study showed that the optimal percentage of using nano kcc-1/ag was 2%.
