Description

Concrete shrinkage test device

technical field

The utility model belongs to the technical field of concrete testing, and more specifically relates to a concrete shrinkage testing device.

Background technique

Concrete refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; water (may contain admixtures) and admixture) in a certain proportion, the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering.

The Chinese patent authorization announcement number is CN214374804U, which discloses a recycled concrete shrinkage test device, including: a bearing mechanism, a fixing mechanism, a measuring mechanism, and a concrete test block. Place the test block on the sleeve, adjust the parallel bar to make the rope vertical, and vertically touch the vertical plates on both sides to the two ends of the concrete test block, record the scales of the digital display dial indicators on both sides at this time, and then measure with the square Put the end vertically on the side of the concrete test block, write down the scale at this time, and when the test time is completed, write down the scales of the digital display dial indicator and square scale on both sides again, and compare them with the data before the experiment to obtain the shrinkage ratio. The concrete test block is set on the sleeve. When the concrete test block shrinks, the sleeve rolls on the wheel rod, and the first roller rolls on the roller groove in the parallel rod, which is beneficial to the accurate measurement of the measuring mechanism.

The clamping and fixing effect of the device on the concrete block is not good, which causes the concrete block to easily shift during detection, and then leads to poor detection accuracy of the concrete block.
