INVESTIGATION OF THE PERFORMANCE OF CSTW AS A PARTIAL REPLACEMENT OF CEMENT IN CONCRETE.

ABSTRACT

Over years, there has been a lot of emphasis on the conservation of the environment by advocating for the use of renewable sources for materials in the construction industry and even in the other fields like energy production. This project is aimed at highlighting the advantages of using mineral admixtures in both improving the characteristics of concrete and conserving the environment.

In the early 20th century, the composition of concrete was primarily cement, water and aggregates. With time and use of technology, the scientists discovered the benefits that came with use of admixtures in the concrete production. Since then, admixtures, both the chemical and mineral admixtures, have been used in enhancing the various properties of concrete.

The aim of this research is to determine the effectiveness of the use of mineral admixtures as micro-reinforcement in concrete. The project will single out use of mineral by-product admixtures in the concrete production for engineering purposes. The paper will give a clear review on the influence of the use of the mineral by-product admixtures in improving the effective and characteristics of concrete.

Generally, use of admixtures in concrete improves its workability and strength, accelerates or retards the setting ting and enhances concrete’s durability. This paper will also seek to clearly outline some of the available mineral admixtures, their advantages and disadvantages in the engineering field.
