The results obtained in a study on the effect of the addition of TiO2 nanoparticles on the mechanical properties and microstructural characteristics of photocatalyticconcretes. Concretes were produced with three types of TiO2: anatase I (10–30 nm),anatase II (50–80 nm) and rutile (10 × 40 nm), with contents of 3%, 6% and 10% inrelation to the mass of Portland cement. Besides these mixtures, a reference concretewas prepared without the addition of TiO2. In the hardened state, tests to determinethe compressive strength and modulus of elasticity were carried out. Also,microstructural aspects of the samples were investigated by scanning electronmicroscopy and mercury intrusion porosimetry. In the fresh state, the influence of theaddition of TiO2 on the concrete compaction and conduction calorimetry curves wasevaluated. The results obtained indicated that, with the addition of TiO2, there was anincrease in the compressive strength at 28 days and a reduction in the modulus ofelasticity of the concretes.
