The invention discloses a device and method for testing the water release capacity of superabsorbent resin for road use, which includes a box body, a plurality of first SAP placement cages, a plurality of second SAP placement cages, and a plurality of SAP embedding and humidity sensing digital display devices; The opening on the right side of the body is provided with a sealing cover, and each first SAP placement cage is respectively fixed at the corner of the inner wall of the box, and each second SAP placement cage is respectively fixed on the inner wall of the top and bottom of the box body, and each SAP is embedded and The humidity sensing digital display device is fixed in the box from left to right; the box is a transparent structure, and the surface of the box is engraved with a number of ring dials, where one ring dial corresponds to a second SAP storage cage, And each second SAP placement cage is located at the center position of the corresponding ring dial. The invention can effectively detect the water release ability of the SAP gel inside the concrete.
Description
technical field [0001] The invention belongs to the field of road materials, and relates to a device and method for testing the water release capacity of superabsorbent resins for road use. Background technique [0002] As a new type of concrete, high-performance concrete can maximize the service life of the structure under the condition of meeting the structural requirements and construction process requirements, but the water gel is relatively small, the early self-shrinkage effect is obvious, and it is prone to cracking and damage, which seriously affects the concrete mechanics. Performance and durability. In order to solve such problems, super absorbent resin SAP is used for early internal curing of high-performance concrete to maintain the high humidity state inside the concrete and provide unhydrated cement with the moisture needed for its continued hydration. Reduce autogenous shrinkage during concrete hydration. [0003] In order to reasonably control the SAP water ...
