The Stability

According to preparation of noise-reducing concrete with the technology of exposed-aggregate, this paper exploits high performance roller compacted concrete used in tunnels. Based on optimizing proportion, exploiting special exposed-aggregate agent and corollary technology, it is necessary that the high strengthening and the stability in the Course of Using of the exposed-aggregate roller compacted concrete should be further studied. During the study on the properties of strength change of common strength grade exposed-aggregate roller compacted concrete pavement, it found that its strength varied from 38.6MPa to 19.2MPa when the depth of exposed-aggregate reached 3mm.This is the main reason that serious damage occurred in one tunnel pavement which is used less than one year. Consequently, this paper carried out experimental study of high strengthening. Furthermore, this paper have been optimized the parameters of exposed-aggregate roller compacted concrete. And the effect is relatively remarkable.

Abstract The results of experimental study of pressure variations inside core box during resin bonded sand filling process are reported. The test core specimens were produced using Laempe® Test Specimen Curing Machine L 1. A special pressure measurement system was designed and built with safety and portability requirements of the foundry environment. Special experiments were conducted to establish the effect of sand deposition on vent permeability.
