The project aims to develop an economical and ecological cutting of the raw material costs of cementitious products by development of a waste based micro filler composite for the concrete industry and at the same time providing an economical and ecological improvements in the technical properties of cementitious products.
Raw material and production costs of cementitious products have increased and are increasing all the time. Simultaneously, as structures of tomorrow become larger and more complex, the materials of construction will be required to meet more demanding standards of performance than those in force today. High performance concrete should have properties such as high workability, dimensional stability, and strength, and long durability in service. This trend has led to the use of higher cement contents and more admixtures in cementitious products. This concerns especially Self Compacting Concrete (SCC) and dry product pre-mixes.
Microstructure of concrete and mortars has a great impact on the properties of fresh and hardened concrete. The project seeks to improve these properties through development of waste based filler composites, which can help to optimise microstructure of cementitious products and reduce the need for high cement and admixture amounts.
The optimised micro-composite is a potential commercial product for the manufacture of high performance mortars and concretes (ready mixed concretes, precast concrete products including SCC and dry pre-mix products), and has the potential of improving the competitiveness of the companies by reducing their raw material costs and of increasing their turnover either as end users or as producers of micro filler composites, or both.
