Marine concrete impacting and grinding test device and test method thereof

Abstract

The invention relates to a marine concrete impacting and grinding test device and a test method thereof. The test device comprises a test container for accommodating simulated seawater and a test piece, a temperature control device for controlling a test environment temperature in the test container, a stirring device for driving a water flow and simulating wave washing, and a communication tube for being connected with the test container and the temperature control device. The test piece is arranged in the test container. When the test device is in use, the test container is filled with an artificial sea water solution. An impacting and grinding medium is paved on the upper surface of the test piece; and stirring impellers of the stirring device are arranged in the test container. The test device having a simple structure is operated conveniently. The development and study of the anti-impacting anti-grinding performance evaluation method of the cement-based material and the novel material of the marine concrete under effects of multiple coupling factors in an actual marine environment, especially in a splash zone can be simulated and promoted. The test device and the test method have characteristics of wide application range, real marine environment simulation, energy conservation, and environment protection and the like.

Description

technical field [0001] The invention relates to a marine concrete abrasion test device and a test method thereof, in particular to a concrete abrasion test device in a simulated seawater environment and a test method thereof. Background technique [0002] Concrete abrasion damage accounts for about 10% of the durability damage, and the combined action of abrasive erosion and other factors will cause a higher proportion of damage. It is currently a water conservancy project, road and bridge engineering, and marine engineering that have abrasive erosion environmental conditions that need to be considered. An important aspect of concrete durability. As the service environment of infrastructure projects becomes increasingly harsh and complex, in-depth research on the mechanism of concrete abrasion and erosion and material design is required. Due to the differences in operating conditions in different environments and different working conditions, the damage characteristics of c...
