The present invention relates to a concrete admixture measuring apparatus having an over-measurement prevention apparatus installed therein. An over-measurement prevention unit comprises: a hollow sleeve coupled with a measurement hopper and connecting the inside and the outside of the measurement hopper; an over-measurement discharge pipe coupled with the sleeve to be able to slide and having an upper end unit located inside the measurement hopper and the lower end unit located outside the measurement hopper and controlling the amount of over-measurement discharge by being elevated along the sleeve when the amount of admixture to be measured changes; and a coupling nut for fixing the over-measurement discharge pipe to the sleeve by being coupled with both ends of the sleeve. Thus, by elevating the over-measurement discharge pipe along the sleeve, the location of the upper end unit of the over-measurement discharge pipe within the measurement hopper can be adjusted. Therefore, the over-measured admixture within the measurement hopper can be discharged into an over-measurement collecting container through the over-measurement discharge pipe of the over-measurement prevention unit as well as the location of the upper end unit of the over-measurement discharge pipe can be adjusted suitable to the amount of the admixture to be measured by elevating the over-measurement discharge pipe along the sleeve when the amount of the admixture to be measured changes, and thereby increasing compatibility. |
