1. Impregnation of concrete structures : transportation and fixation of moisture in water repellent treated concrete
Abstract : Water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE

2. Composite Action and Confinement Effects in Tubular Steel-Concrete Columns
Abstract : Composite columns composed of concrete-filled steel tubes (CFT) have become increasingly popular in structural applications around the world. This type of column can offer many advantages, for instance, high strength, ductility, and large energy absorption capacity, as well as increased speed of construction, positive safety aspects, and possible use of simple standardized connections.

3. Dry Classification of Fine Aggregates for Concrete and Asphalt
Abstract : Aggregate is defined as particles of rock which in combination are used as a civil engineering material. It is used in bounded form in asphalt and concrete. Historically natural sand has been used as fine aggregate for concrete production in Sweden. READ MORE

4. Structural Behaviour in Concrete Frame Corners of Civil Defence Shelters Non-linear Finite Element Analyses and Experiments
Abstract : From a safety point of view it is important that a concrete structure, apart from necessary load capacity, also is able to show ductile behaviour that allows redistribution of forces so that a local failure not lead to total collapse of the structure. A structure's ability to exhibit such behaviour is highly dependent on the reinforcement detailing of the joint connections between its independent members. READ MORE
