Abstract:
An experimental program has been carried out to establish specifications for constituent materials of high-performance concrete (HPC) mixtures. Many general recommendations can be found in the bibliography, but not enough to determine precisely how to specify cements, aggregates, and admixtures for HPC. Cement has to be selected not only according to its strength but also its water demand and setting time. Suitable aggregates are those with good mechanical properties, controlled by the Los Angeles coefficient. In addition, water demand of the aggregate must be low, controlled by its absorption and shape coefficient. Also, a mix proportioning method has been established to proportion HPC mixtures for strengths up to 110 MPa.
