| Abstract | The Thesis discusses in detail the various properties of Hydraulic Cement. The fresh, mechanical and durability properties of hydraulic cement have been compared traditional OPC Cement Concrete. From the test results it becomes very clear that Hydraulic cement has similar properties as OPC cement concrete and can replace OPC while maintaining similar performance. In the second part of the thesis we discuss the requirement for optimisation of concrete mixes and how Particle Packing Models can be useful for achieving concrete with strength and durability similar to that of traditional practice of mix design but with very low cement content. Two particle packing models are employed Packing Factor model and Modified Andreasen model to achieve our target of mixture optimisation and reduction of cement content. Properties such as fresh, mechanical and durability of these optimised concrete mixes were compared with concrete produced using traditional mix proportioning methods. With the use of these two methods it was possible to achieve concrete with compressive strength of 35 MPa and above with cement content as low as 200 kg/m3 but with significantly better fresh, mechanical and durability properties. It could be concluded that traditional methods of mix design can be easily replaced with more scientific methods of mix proportioning using PPM thereby saving around 60-150kg/m3 of cement. |
