supervisor Mr Roshan Lal‚ I completed this project. I did this project in the final year of my Masters and invested 12 months for this project. BACKGROUND 2.2 With multiple crack formation‚ the conventional concrete loses the tensile resistance. With the help of crack arresting mechanisms of fibre‚ the concrete strength is enhanced. Beam-column joints play a major role so that it should be with proper strength

And defined as "any material manufactured with aggregate and cementitious binder‚ intended to resemble in appearance‚ and which may be used in a similar way to‚ natural stone". Concrete Is a building material made of sand and gravel mixed with cement. Like stone‚ it has high compressive strength. It doesn’t easily crumble or break down when subjected to heavy weight. It does not corrode and is fire resistant. For stronger

movements of ground. 6) Cracks due to vegetation. The various causes of formation of cracks and measures adopted to prevent them are described below: 1) Cracks due to moisture changes. We know that most of the building materials like bricks‚ concrete‚ mortar‚ stone‚ timber etc. have pores. Hence these materials increase in size or expand on absorbing moisture and decrease in size or shrink on drying. Shrinkage on account of drying out of moisture contents in building materials is one of the

If stored‚ it will harden‚ and once hardened‚ is useless. This case is analogous to cement or concrete providers: Once prepared and placed within a cement truck‚ there is approximately a 90 minute window in which to deliver and apply the concrete or the concrete properties begin to change and harden‚ and having changed and begun to harden‚ the concrete becomes not applicable for the specific job for which it was intended.

1. INTRODUCTION 1.1 General Foundry sand is high quality silica sand with uniform physical characteristics. It is a byproduct of ferrous and nonferrous metal casting industries‚ where sand has been used for centuries as a molding material because of its thermal conductivity. It is a byproduct from the production of both ferrous and nonferrous metal castings. The physical and chemical characteristics of foundry sand will depend in great part on the type of casting
