| titleOfInvention | Device for testing density and water absorption of fine aggregate |
| abstract | The application discloses a device for fine aggregate density and water absorption are experimental, include: the stirring device comprises a driving mechanism, a base, a rotary table, a charging barrel, a support, a bracket, a box body and a stirring rod, wherein the driving mechanism and the support are fixed on the base; the driving mechanism drives the turntable to rotate; the rotating disc drives the material barrel to rotate; the turntable drives the support to rotate, and the support drives the stirring rod to rotate; the stirring rod extends into the charging barrel, and the other end of the box body is movably connected with the support; the support is provided with a temperature-adjusting blower, and a blowing port of the temperature-adjusting blower is positioned right above the charging barrel. The device solves the problems that the fine aggregate is turned and stirred manually in the density and water absorption tests of the fine aggregate to evaporate water on the surface of the fine aggregate, the method is simple to operate and is not limited by conditions, but the manual operation mode wastes time and labor, the fine aggregate is easy to lose, the water is not easy to evaporate, and the test error is large. |
