Uhpc formulation
WebUltra-high performance concrete (UHPC), when used in field-cast connections between prefabricated bridge elements, can create robust connections which emulate monolithic components. Traditional UHPC formulations tend to express a delay prior to setting and initial mechanical property development. WebSuperfluid UHPC formulation allows filling of thinnest sections in a mold. ... The UHPC matrix in lightweight aggregates makes this material especially useful in structural elements with visible surface. It offers the same quality of surface finish like UHPC at densities between 1.2 - 2.2 kg/L. ...
