متن کاملResearch on Factors Affecting Concrete Cover Measurement
Concrete cover is the distance from the surface of the concrete to the surface of the reinforcing bars embedded in the concrete. Ensuring sufficient concrete cover is critical for the durability of some concrete structures subject to poor environment during their service life. Concrete cover can be measured using covermeters. In this paper, some factors affecting cover measurement were briefly ...

The Importance of the Factors Affecting Concrete Shrinkage
The loss of water from hardened concrete (stored in unsaturated air) causes drying shrinkage. Shrinkage of hardened concrete is influenced by various factors in a similar manner to creep under drying conditions. High cementitious materials content, particularly fine particles will reduce bleeding, but increase long term drying shrinkage. (The time of sawing the joints for induced cracking is no...
متن کاملExplaining the Factors Affecting the Distribution of Land Use Change Interests Using the Communicative Planning Framework
Urban land use change is one of the key issues in urban planning that has been addressed by researchers in many different aspects, especially from the perspective of space. But the point that has been overlooked in various studies is that the analysis of different aspects of land use change is not limited to classical and spatial factors, and because of the various interest of land use change, ...
