Nanoclay- supported Preyssler heteropolyacid as a new and effective nanocomposite was used to improve the compressive strength of concrete. The cement pastes used in this study were a mix of water, ordinary Portland cement and nanoclay- supported Preyssler heteropolyacid. The nanoclay- supported Preyssler were added into the concrete with different concentrations of 1, 2, 3, 4 and 5% by the weight of cement amount. Water/cement ratio was 0.35 and the dimension of the cubic samples was 15 ×15 ×15 Cm. Compressive strength tests were done on hardened specimens. The obtained results revealed that the addition of nanoclay- supported Preyssler heteropolyacid into the concrete samples led to increase in compressive strength of concrete specimens equal to 23.2% at 28 days for dosage of 3%.
