AI Technical Summary

Technical Problem

In existing technologies, it is difficult to accurately control the amount of water and ensure uniform distribution when fine aggregates reach a saturated surface-dry state, leading to inaccurate test results and prolonged testing time.

Method used

A quantitative spray mixing device for fine aggregates in a saturated surface-dry state is designed. By setting a quantitative sprayer and a stirring rod above the mixing pot, the water volume can be precisely controlled and evenly distributed. Combined with mechanical stirring, the saturated surface-dry state can be quickly achieved.

Benefits of technology

It achieves precise control and uniform distribution of water, shortens the test time, ensures the uniformity of fine aggregates, and is suitable for testing the density and water absorption rate of fine aggregates.

Abstract

The utility model belongs to the field of engineering design, and particularly discloses a fine aggregate saturated surface dry state quantitative spraying and stirring device for assisting fine aggregate density and water absorption tests, which comprises a base, a stand column fixed on the base, a cross rod movably connected with the top end of the stand column, and one end of the cross rod capable of rotating around the top end of the stand column. Through the arrangement of the quantitative sprayer and the stirrer, not only can the amount of water added each time be accurately controlled, but also atomization spraying adding is implemented, and the materials are uniformly dispersed in the aggregate under the assistance of mechanical stirring, so that the aggregate can reach a saturated surface dry state more quickly, and subsequent tests are facilitated.
