As the development of concrete technology, subzero concrete are widely used. To satisfy the engineering re-quirements at subzero temperature, some technologic measures are adopted on self-compacting concrete design under con-stant subzero temperature, such as analyzing by new maturity theory, self anti-freezing combined additional measures and new admixture adopting. Meanwhile, the workability of concrete is researched, and some measures on design, production and construction of concrete are proposed in this paper.
