| Self-consolidating concrete represents one of the most important advances for the concrete industry. Due to the rapid growth of the use of this new concrete technology, it is evident that research focused on its mechanical properties compared with conventional concrete is requested in order to fulfill design requirements and codes. Self-consolidating concrete modulus of elasticity property, using materials commercially available in Puerto Rico, is evaluated in this thesis to determine whether it is actually lower than that of conventional concrete or not. Other properties such as compressive strength, segregation tendency and slump flow were also examined.;Forty self-consolidating concrete mixtures were made under laboratory conditions varying different water-to-cement ratios, coarse-to-total aggregate ratios, and total aggregate volume content. Self-consolidating concrete modulus of elasticity appears to have the same value as that obtained in conventional concrete mixtures, as long as both type of concrete have similar aggregate volume content. Expressions given by ACI code to compute modulus of elasticity continues being acceptable to predict self-consolidating concrete modulus of elasticity. |
