Application of Industrial by Product in High Strength Glass Fiber Reinforced Concrete

摘要

With the ecological imbalance in the nature due to exploitation of natural sand from rivers, there is much need to utilize the industrial wastes in concrete as a part to replace the natural sand deficiency and also as to develop sustainable environment in construction industry. High strength and durability properties being the key components of High performance concrete can be produced by using some admixtures like fly ash and silica fume. In the present study, fly ash and silica fume are taken as steady replacement of 15% and 10% respectively for cement. Bottom ash is introduced in place of sand at the variations of 0%, 10%, 20%, 30%, 40% and 50%. Glass fibers of 0.2% are added as extra ingredient as to improve some properties. The properties of strength, drying shrinkage and water absorption are studied for the M60 grade concrete designation. The results showed that the concrete with 40% bottom ash had the optimum strength.
