AN EXPERIMENTAL STUDY ON AN ECO FRIENDLY HYBRID FERROCEMENT SLABS USING SELF COMPACTING MICROCONCRETE MADE WITH SILICA FUMES. Deepashri and K. Ramadevi
The usage of concrete as a construction material and the production of Portland cement, an important ingredient of concrete, leads to the significant amount of CO2 emission to the environment. Hence the concrete industry is a major CO2 emitter and thus contributing towards global warming is not likely to dramatically reduce the CO2 emissions, cement replacement by a supplementary material or mineral additive, such as silica fume, which is not associated with CO2 emission, can substantially reduce the aforementioned problem. The present work discusses the benefits of incorporating mineral additives in concrete and shows that these additives can improve both the mechanical and physical properties of the end-product, and hence its durability, with a reduction in cement content. The study was carried out with the flexural behaviour of Hybrid Ferrocement (HF) slab panels made of Self Compacting Micro Concrete. The test results of simply supported roof slab panels are presented. The results indicate that the self compacting micro concrete with partial replacement of cement by silica fume can be effectively used for Ferrocement roof slab panels.
