AI Technical Summary
In existing technologies, concrete shrinkage tests require pre-cutting of concrete samples according to the size of the testing device, which affects testing efficiency, and there is a lack of devices that can adapt to concrete of different sizes.
A horizontal cement concrete drying shrinkage test device is designed, which adopts a lifting mechanism, a moving plate and a sliding mechanism, combined with a dial indicator and a test head to realize automatic adaptive testing of concrete of different sizes. The plate can be unfolded or folded through a servo geared motor and a linkage structure to optimize space utilization.
No need to pre-cut concrete, improving testing efficiency, adapting to testing concrete of different sizes, saving space, and increasing testing speed.
