Abstract: Studying the impact of XYPEX admixture on the frost resistance of nanometer CaCO₃ concrete can provide a scientific basis for the design and construction of concrete engineering, and improve the durability and reliability of concrete structures. The analysis was conducted on the influence of xypex admixture on the frost resistance of nanometer CaCO₃ concrete. Six types of nanometer CaCO₃ concrete specimens were prepared with XYPEX admixture content set at 0%, 0.8%, 1.2%, 1.5%, 1.8%, and 2.1% of the total weight of cement and fly ash. The frost resistance of the nanometer CaCO₃ concrete was tested using equipment such as a concrete rapid freeze-thaw tester and a concrete dynamic modulus measurement instrument. Experimental results showed that the addition of XYPEX admixture had a positive impact on the frost resistance of nanometer CaCO₃ concrete. It could reduce the mass loss rate, relative dynamic modulus, dynamic modulus loss rate, and compressive strength loss rate.

Keywords: XYPEX admixture; nanometer CaCO₃ concrete; frost resistance; mass loss rate; relative dynamic modulus; dynamic modulus loss rate; compressive strength loss rate.
