Abstract: A latex-modified concrete composition using high strength cement is provided to be more inexpensive than a very early strength-latex modified concrete and help accomplish a relatively early traffic opening by a rapid completion of a construction work. A latex-modified concrete composition using high strength cement is used for a work for repairing broken portions of paving and comprises cement, coarse aggregate, and water. Latex is added to the concrete formed by high strength cement. A content of the latex is 10-15wt% based on the cement. The coarse aggregate in the concrete has a maximal dimension of 13-25mm. A ratio of the water-cement in the concrete is 29-35wt.%. An anti-foaming agent is added in a 0.3-0.6wt.% of amount.
