Predicting the Permeability of Pervious Concrete (Enhanced Porosity Concrete) from Non-Destructive Electrical Measurements
The effectiveness of a pervious concrete pavement to transport water through it depends on the intrinsic permeability of the system. However, this characteristic is usually defined in terms of the porosity of the material. It has been observed that porosity alone is an inadequate indicator of the permeability of pervious concretes, since the permeability depends on pore sizes, geometry and conn...
متن کاملThe Use of Non-destructive Methods to Analyse Fruit Quality
This article is divided into three parts. The first part, the most important one, deals with spectroscopic methods. Different regions of the electromagnetic spectrum are useful for fruit quality characterisation, in particular the visible and near-infrared regions. Concerning the visible one, studies have been carried out on apple, apricot, cherry, mango, peach, red table grape and tomato, when...
متن کاملNon-Linear Non-Destructive Evaluation of Concrete
This paper explains non-linear non-destructive evaluation of concrete aimed at examining the occurrence of non-linearity under non-linear wave propagation through the concrete. Standard cubic concrete sections in damaged and undamaged conditions were investigated. The specimen was first damaged under compression testing and then subjected to non-linear ultrasonic evaluation in two directions i....
متن کاملExamining Concrete Cores by Non-destructive Techniques
Computed Tomography (CT) scanning has served as an important non-destructive research tool by providing twoand three-dimensional images particularly in medicine, biology and materials science. An example of its application in the area of materials is reported. Experimental study was carried out to investigate the effect of location within column element on the strength and porosity characterist...
متن کاملAlternative methods to determine the ice load on concrete dams
Dams in countries with cold climate are subjected to ice loads during the winter, and these may have significant influence on the dam stability. The design value of the horizontal ice load varies between 50 – 200 kN/m from the South to the North of Sweden, according to the Swedish guideline for dam safety (RIDAS 2011). However, the size of the ice load cannot be dictated by the geographic locat...
