Characterization and adaptability of layered double hydroxides in cement paste

Layered double hydroxides (LDHs) improve the durability of concrete, whereas theirs characterization and adaptability in cement-based matrix has not been systematically investigated. Setting time, chemical shrinkage, rheology, compressive strength, hydration degree, pore structure as well as micro-mechanisms of high sulphate-resistant Portland cement (HSRPC) incorporating different LDHs, namely, CaFe-NO3 LDHs (LDHs-CF), CaAl-NO3 LDHs (LDHs-CA),...
