Prestressed concrete construction Prestressed concrete Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams‚ floors or bridges with a longer span than is practical with ordinary reinforced concrete. Prestressing tendons (generally of high tensile steel cable or rods) are used to provide a clamping load which produces a compressive stress that balances the tensile stress that the concrete compression member would otherwise

Strength of concrete Chapter 6 Properties of concrete :- Strength Durability Impermeability Volume stability Strength of concrete is the most valuable property. What is strength? Strength depends on the physical structure and volume of hydration products. Therefore it gives an idea of the quality of concrete. Note :- strength depends less on the chemical composition of the paste and more on the physical structure

Shrinkage in concrete or mortar depends on a number of factors • Cement concrete: Richer the mix greater is the drying shrinkage. • Water content: More water in mix induces greater shrinkage • Aggregates : Large aggregates with good grading has less shrinkage for same workability as less water

POLYMER COCNCRETE 1. Introduction Despite being thought of as a modern material‚ concrete has been in use for hundreds of years. The word concrete comes from the Latin concretus‚ which means “mixed together” or compounded. Concrete is an extremely popular structural material due to its low cost and easy fabrication. Concrete is made up of sand or stone‚ known as aggregate‚ combined with cement paste to bind it. Aggregate can be of various sizes. It is broadly categorized as fine (commonly

Musique Concrete Music has existed since the beginning of time‚ evolving and changing with the times and culture. From monks chanting to the Beatles in the 1960’s‚ there is a long line of the evolution of music. The existence of musique concrete was another step in the world’s music history. But before going any further perhaps the definition of musique concrete should be specified. “ Musique concrete is the name given to a class of electronic music produced from editing together fragments of

7166M01.qxd_lb 6/3/09 09:38 AM Page 1 1 BASIC CONCEPTS 1.1 INTRODUCTION Concrete is strong in compression‚ but weak in tension: its tensile strength varies from 8 to 14 percent of its compressive strength. Due to such a low tensile capacity‚ flexural cracks develop at early stages of loading. In order to reduce or prevent such cracks from developing‚ a concentric or eccentric force is imposed in the longitudinal direction of the structural element. This force prevents the cracks
