Factors Affecting Performance of Concrete During Fire

Inevitably, concrete structures are exposed to fire and high temperature during its life service which creates changes in concrete properties detrimentally and also sometimes causing failure. Therefore, it is considerably significant to understand factors that control concrete performance during fires.

Survey on precast concrete industry in Sri Lanka

The first appliion of precast concrete in Sri Lanka was in port related structures in 1949. As a solution to deterioration of RCC maritime structures prestressed precast concrete was introduced and Dr A.N.S. Kulasinghe has played a major role in this regard. This technology was introduced to building construction in mid 1950''s and precast

Partner ProfileProf. Sujeeva Setunge – SmartCrete CRC

My first job as a Civil Engineer was managing a construction site of a reinforced concrete water retaining structure where I learnt the challenges of moving from theory to practice. My interest in concrete led to selection of a Ph.D research project on structural properties of very high strength concrete, which developed a failure criterion and a constitutive model for concrete with strengths

Pre-Cast Concrete - Portland Cement Association

Precast concrete is available in many shapes and sizes, including structural elements and unreinforced pieces. Panels are the most common meers used in building construction, and may serve as structure or cladding or both. As structural-architectural panels

Post-Tensioned Concrete - Interspan

Post-tensioned concrete can most easily be defined as “pre-compressed” concrete. A compressive stress is put into a concrete meer before it begins its working life and is positioned in areas where tensile stresses will develop under working load. Concrete is

A. N. S. Kulasinghe - Wikipedia

2020/6/8· Hi, In simple words, there are three major types of reinforcement used in prestressed concrete. Spalling reinforcement: this type of stresses are generated behind the loaded area of the block which is anchored and this causes a breakaway of concrete surface. 30 dresses include strength incompatibility with all gems ratio and various trajectory stresses.

Post-tensioning systems | VSL specialized leader

In the early fifties, post-tensioning systems for the prestressing of concrete were developed by specialists, such as VSL in Switzerland. Even though post-tensioning is a mature technology, it is still a fantastic tool for the design engineer as it enables the active definition of the internal load path in concrete structures by superposing a favorable state for the internal stresses.

Coined half precast concrete slab and post-tensioned slab topping system for basement parking structures …

Abstract It is known that the prestressed half PC (precast) slab system has many advantages such as a reduced construction period and use of long-span one-way slab systems over reinforced concrete and half PC slab systems without prestressing. For this reason, prestressed half slabs are commonly used for both residential and basement parking structures in Korea and other countries. The
