ppt on repair and rehabilitation techniques

Introduction

The success of repair activity depends on the identification of the root cause of the deterioration of the concrete structures. If this cause is properly identified, satisfactory repairs can be done for the improvement of strength and durability, thus extending the life of the structure, is not difficult to achieve. General procedure in the repair of distressed concrete structure:

Support the structural members properly as required.
Remove all cracked, spalled and loose concrete.

advance formwork techniques ppt

Building a high rise, or other large buildings, is typical for urban areas. High-rise buildings are rapidly becoming a developing nature of urban zones due to increased population and businesses. The core of high-rise buildings is one of the most important elements in such gigantic structures. Fast and efficient construction of the concrete core of a high-rise building is essential to maintain phased progress on other parts of the building. Formwork is one of the most important factors in determining the success ....etc

modern Wastewater Treatment Methods
& Disposal techniques
Satisfactory disposal of wastewater, whether by surface, subsurface methods or dilution, is dependent on its treatment prior to disposal. Relatively simple wastewater treatment technologies can be designed to provide low cost sanitation and environmental protection while providing additional benefits from the reuse of water.Adequate treatment is necessary to prevent contamination of receiving waters to a degree which might interfere with their best or intended use.
The whole ....etc
