As the concrete production process is simple and its constituent materials are affordable and relatively inexpensive the concrete can be considered an easily obtainable material and low cost. Therefore, the technical use of the concrete for diversified purposes justifies the permanent interest in its study. One of the basic steps in the concrete production process, which seeks to meet specific needs as well as design requirements, is dosing. That is, the choice and proportion of the constituent materials of the concrete. In this context, the water/cement factor is presented as one of the main parameters for dosages of conventional concretes, since this is characterized as a determinant parameter in the reach of the desired final resistance. However, it is seen that the water/cement ratio has restricted scope, in range of values as in types of concrete. In this sense, the present work develops in order to expand the universe of a new concept with regard to the dosage of different types of concrete, voids/cement factor, since it is an index whose range tends to be higher than water/cement factor commonly used. The study covers the evaluation of the influence of cement content, porosity and voids/cement factor on the simple compression strength and tensile strength by diametral compression of different traces of conventional concretes. |
