Σύνοψη

The work accomplished in this project dialed with the use of a concrete additive, Micro silica, and its use in the concrete industry, concerning the effects that it has in altering the way that concrete works. This project investigates the main properties of micro silica, its uses in some actual projects and the values achieved with its use, in testing, compared to ordinary concrete. Micro silica changes and enhances all the properties of concrete, in the almost full range of them in a good manner. All the major properties of concrete that micro silica affects are discussed in the project.
The project was performed using materials made in Cyprus, except for the microsilica, which is imported and the importing company provided us with everything we needed. A complete pathway was followed in preparing the samples, including sieving and separation of the raw materials (aggregates). The experimental work took place in the Institute and the results carne close to the ones expected. Micro silica concrete gave excellent results in the permeability test which is its main attribute in concrete. It also showed approximately the expected results in compressive strength but there was a deviation in the quality of the aggregates, which was inferior for the micro silica concrete samples (a different quality was brought by another team working alongside us).
Micro silica is a product that gives concrete all the properties that cement lacks to provide or is inadequate to resist certain problems that may occur. It is a very important material and its use is valuable in rough conditions.
