Water influence determination of Tiquipaya Municipality in the resistance to the concrete compression

Although the use of potable water for the concrete manufacture is recommended, this resource is not always available, especially in those municipalities where there are different sources of water with unknown composition. In this sense, the objective of the present study was to determine the influence of water from different sources of the municipality of Tiquipaya-Cochabamba, on the compressive strength of concrete. The methodology consisted on the concrete cylinders manufacture with three different water sources: Campus Univalle, municipal well and municipal irrigation canal. Compressive strength was determined at 7, 14, 21 and 28 days of age. The results show that the cylinders made with the Univalle Campus water have the best results, with a compressive strength of 274 kg/cm2 at 28 days, while the cylinders made with the other sources, well and irrigation canal, 234 and 211 kg/cm2, respectively. Potable water from Campus Univalle was suitable far use in the concrete manufacture, once the results were greater than those projected, contrary to the use of other non-potable sources, which had a negative influence on this property. lt is important that previous studies of the water to be used in the concrete manufacture be carried out to obtain the expected results, thus guaranteeing quality and safety.
