On the demolition of an existing structure made of high-strength and high-fluidity concrete, we determined various quality parameters and their variations by place. Parameters included compressive strength, Young's modulus of elasticity and coarse aggregate distribution by the sampled core, and concrete fill capability and carbonation depth of surfaces cut by wire-sawing. Uniformity of the quality of the structure was evaluated by the variance analysis of the data. It was found that the quality of the high performance concrete was acceptable though the slight variation in a structure was observed.
