High-efficiency alkali aggregate test box

Abstract

The invention relates to a high-efficiency alkali aggregate test box, which comprises a box body, a test-piece box, a temperature measurement sensor, a control cabinet and a water incoming and out-coming circulation system; a bracket is arranged in the box body; the test-piece box is placed on the bracket; the water incoming and out-coming circulation system comprises a water tank, a water inlet pipe, a magnetic pump and a water outlet pipe; the water tank is positioned at the lower side of the bracket; the water tank is connected to the magnetic pump outside the box body through the water inlet pipe; the magnetic pump is communicated with a region, outside the test-piece box, in the box body through the water outlet pipe; a suction head vertical to the head diameter is arranged at the front end of the water inlet pipe, so that the water inlet pipe is in a T shape; a plurality of water inlets are formed in the pipe wall on the lower side surface of the suction head; a box cover is arranged on the top of the box body; a ventilated temperature measurement hole is formed in the box cover; the temperature measurement sensor stretches into the box body through the ventilated temperature measurement hole; a balanced water level hole is also formed in the side wall of the box body; and the height h from the balanced water level hole to the horizontal plane is not more than the height H from the upper edge of the test-piece box to the horizontal plane.

Description

technical field [0001] The invention relates to the field of building material instruments and equipment, in particular to an alkali aggregate high-efficiency test chamber. Background technique [0002] The alkali aggregate test chamber is a special equipment for controlling the test temperature and test time when performing expansion test on concrete aggregate. At present, the experimental body of alkali aggregate is mainly to control the experimental temperature within the range of 38 °C ± 2 °C, and maintain a certain humidity, so as to perform air curing on the test pieces placed in the box. For example, the Chinese invention patent "Alkali Aggregate Test Chamber", the application number is 201220745982.3, discloses a box body, a control roller, a circulating water pump, a heating pipe arranged in the box body, and a bracket for placing a test piece box; There is a box cover on the surface, the control cabinet is set on one side of the box, and it is set under the brack...
