Abstract
The present invention relates to a measurement instrument for measuring the gas content of fresh concrete. A spoon-shaped sampler collects a certain amount of freshly mixed concrete to be put in a barrel-shaped container combined with a flange, water is filled in a water filling pipe on the top of the container, air in the container is exhausted by an exhaust valve at the top, and the exhaust valve is closed. A spoon cover opening mechanism opens a spoon cover, the concrete is scattered to fall into the water of the container, a valve on an exhaust pipe is opened, and a level bottle moves up and down to pump the air in the container to a thin glass pipe with scales; the valve on the exhaust pipe is closed, and the level bottle moves up and down so as to make the water level of the level bottle and the water level of the glass pipe on the same horizontal line. The air occupation volume of the glass pipe is the air content of a concrete sample measured under the atmospheric pressure. The measurement instrument has the characteristics of simple operation, high measurement precision, etc.
