Σύνοψη

This project is an experimental one and the main purpose of it, is to design Concrete of Grade 40 using Admixtures and local aggregates and cement. In order to achieve this, some trial mixes with various values of water/cement ratio are performed, following the design Mix Method of Concrete. Mix proportions are combined with a suitable quantity of super plasticizer.
The project begins with a reference to the materials using in concrete (aggregates, cement, water). Aggregates is the
section mainly discussed, especially their influence on
concrete strength.
In the second chapter the properties of concrete are
discussed. Strength workability and durability are explained analytically and their importance to concrete technology is mentioned.
Chapter 3 referred to the various types of admixtures
especially to superplasticizers indicating their effects on
concrete properties. In addition th|e applications of these
chemical compounds are mentioned.
Chapter 4 explains Mix Design method and the relative data,
graphs and tables are provided.
In the experimental part the designing of the mixes and the
necessary adjustments which are performed to this project are
provided. Also the procedures for making and curing concrete
cubes as well as the compressive tests are written. Moreover
the apparatus are explained and photographs provided.
Results are provided in tables are comments are written about
these results. Finally conclusions are written and the main
points of the project mentioned.
