measuring SCC stability by digitally processing the image of the cut concrete surface. This paper describes a study effort that set out to realize this objective using image processing technology. Specifically, the steps of the study, as reflected in this organization of this paper, are as follows:
The mixing operation consists of rotation or stirring, the objective being to coat the surface the all aggregate particles with cement paste, and to blind all the ingredients of the concrete into a uniform mass; this uniformity must not be disturbed by the process of discharging from the mixer.
The processing technology and preparation of concrete Design of mix proportion. In the preparation of concrete,according to the requirements of the engineering, such as workability, strength and durability, the raw materials should be chosen reasonably and the propotion should be confirmed to achieve the economical and applicable purpose.
