What Is Estimate? The estimated or anticipated cost of the project is an estimate that is commonly calculated well before the project is taken up. The main goal of estimation is to encourage us to always understand the cost of work prior. Appropriate estimation is planned by detailed estimation in specific item wise.

When the formwork is erected the concrete can be poured. When the concrete has reached the required strength the formwork can be poured. If the steel had been placed too close to the surface and the concrete had been poured then over time the steel may become exposed to moisture and corrosion will commence.

Formwork pressures are function of height (including the height from which concrete is dropped into the forms) and are affected by concrete workability, rate of stiffening and rate of placing. Exceeding this limit may lead to unacceptable formwork deflections, loss of grout / concrete at joints, or even collapse.

There is no grout loss, such as that from badly fitting formwork, which results in poor quality concrete like shown below. By careful selection of materials and finishing processes, a wide range of high quality finishes can be obtained.

There are two ways of overcoming this problem: Embed another material in the concrete which is strong in tension – reinforced concrete Remove the tension altogether – by arching or prestressing. In practice, reinforced concrete beams are designed on the assumption that cracks will occur under their service loads.

Following are the cases, which affect creep in concrete: When the aggregate volume is increased, creep will be less as the aggregate is more rigid than the cement paste. Water within the hardened cement paste is forced to more as a result of the applied load.

What is Prestressed Concrete? Concrete can withstand a great amount of compressive stress but it has a very low tensile strength. Because of low tensile strength, concrete gets cracks when subjected to maximum load. Why prestressed concrete is used? When water comes in contact with these cracks the steel gets corroded.
