Material Durability And Weather

17.07.2008
Material durability is a major concern in structural design as it affects the particular material service life. A research is currently being conducted to investigate the effect of Malaysia's tropical climate on the strength of epoxy resin concrete structure.

The deterioration of a particular material depends on how and to what extend it interacts with its surrounding. Thus, durability is definitely one of the main concerns in designing as it directly relates to the maintenance of the structural integrity of a structure throughout its service life.

Malaysia's tropical climate can pose hazard to many concrete structures as high temperature and high humidity can affect the chemical interaction between concrete's alkaline property and its surrounding. In this case, concrete durability is related to its ability to withstand exposure to condition such as UV radiation, temperature, rain and wind.

In many advanced countries, epoxy resins concrete are used in many applications such as aircraft, aerospace, and composite reinforcing concrete products which includes repair and appraisal works in civil engineering particularly as reinforcement in concrete.

The resin is formed by the chemical reactions of epoxy groups with amines, alcohols, phenols and others.

Epoxy resin concretes exposure to four season's climate has been investigated and significant effect was found on the strength properties of the concretes. There is a need to understand the behaviour of epoxy resin concrete under Malaysia climatic stress. When the behaviour of its strength is understood, design durability and repair works for structures with epoxy resins in this region can be predicted.

The objectives of this research, therefore, are to construct a correlation between atmospheric exposure and wet-dry condition with the durability of epoxy resins concrete; to predict durability from the permeability, porosity, and shrinkage testing; and to compare atmospheric exposure with laboratory conditions.

This research is conducted by Idawati Ismail, Mohd Ibrahim Safawi M Zaid and Azida Rashid of Universiti Malaysia Sarawak and Abdul Aziz Ismail of Universiti Teknologi Malaysia.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
