THE ROLE OF SPECIAL ADDITIVES INTHE STRENGTHENING OF REINFORCED CONCRETE

The study aims to identify the role of the special additives for strengthening reinforced concrete used in construction, as the researcher presented the theoretical frameworks for the definition of reinforced concrete and its components as well as the special additives used in  concrete, identifying its types and components.
The experimental method based on the experience was used to reach the role of special additives to strengthen reinforced concrete and the researcher performed an experiment using the substance (CF/ACC) in its liquid form.
The study reached the following:
Control batch (without additives), produced fresh concrete slump equals 7cm, and the experimental batch with additives (CF/ACC) produced fresh slump equals 7cm, the effect of additives on the level of concrete slump in the experimental batch, where the additives proved its effectiveness in concrete stability.
The study also recommended the following:

The need to use the additives to the concrete because of its active role in enhancing the properties the reinforced concrete.
The additives should not be mixed to the concrete except after the approval of the engineer who responsible for the project.
Determine the appropriate materials for the required operations.
The need to make mini tests to make sure of the concrete and additives effectiveness before starting in casting the concrete in the site.
