Experimental study on sulfate erosion resistance of nano-CaCO₃ modified concrete

In the saline soil environment of western China, salts can corrode ordinary cement concrete seriously, and the durability of concrete structure deteriorates gradually until it fails. This impedes the application of ordinary Portland cement concrete in this area. Aiming at the problem of the short service life of concrete in the harsh environment of western China, this study examines the performance of nano-CaCO 3 modified concrete in a sulfate...
