Determination of flow front velocity and optimal injection pressures for better impregnation of E-glass with polyester in resin transfer mold [PDF]
INCAS Bulletin, 2019 Flow front velocity of resin plays a key role in yielding better impregnation of fiber reinforcement in resin transfer molding to fabricate quality composites. A video camera was used to capture the patterns of resin flowing below the grid lines drawn on

Compaction behaviour of clay [PDF]
, 2008 This paper presents an experimental study of the compaction behaviour of non-active clay. One-dimensional static compaction tests were carried out at high and medium water content with matric suction monitoring using Trento high-capacity tensiometers. At

Microscopic investigations on the air-void characteristics of wet-mix shotcrete
Journal of Materials Research and Technology, 2019 This paper aims to perform microscopic investigations on the air-void characteristics of wet-mix shotcrete before and after the spraying process. Both air-void analysis (AVA) and image analysis (IA) were used to monitor the air-void characteristics of ...

Minimum Void Ratio Model Established from Tailings and Determination of Optimal Void Ratio
Geofluids, 2021 Minimum void ratio of tailings and its value change with fine content and are key design parameters for tailing consolidation and seepage stability. Based on the distribution of tailing grains with the sedimentary beach, we establish a minimum void ratio

A GPR-Based Pavement Density Profiler: Operating Principles and Applications
Remote Sensing, 2021 Density is one of the most important parameters in the construction of asphalt mixtures and pavement engineering. When a mixture is properly designed and compacted, it will contain enough air voids to prevent plastic deformation but will have low enough ...
