ABSTRACT:
A cementitious composition comprises a ground sulfoaluminous clinker, a ground Portland cement clinker (preferably rapid hardening Portland cement clinker), calcium sulfate, aggregate (especially sand and a coarse aggregate such as granite) and metal (e.g. stainless steel) fibers. The composition may also comprise a plasticizer and agents for controlling setting and hardening. The reinforced concrete produced from the compositions is useful in offshore applications, e.g. as a coating for the weld areas between lengths of steel pipe to be laid under water.
