Non Destructive Testing and Serviceability Properties of High Strength Glass Fiber Reinforced Concrete

Abstract

Concrete, an abundant material used in the construction industry uses huge amount of natural resources. These resources being exploited rapidly due to rapid growth in infrastructural construction resulted in the use of industrial wastes for concrete manufacture. The mechanical properties, durability properties are also important for the better understanding of the concrete to use it in the industry. Concrete of high grades such as M60 can be produced with fly ash, bottom ash and silica fume. In the present investigative study, Fly ash and silica fume combindly used as a cement replacement material at 15% and 10% respectively to that of cement. Bottom ash is used as a replacement to fine aggregate at the variable replacements of 0%, 10%, 20%, 30%, 40%& 50%. The compressive strength, non destructive tests such as rebound hammer test and ultrasonic pulse velocity test, durability tests like acid resistance, sorptivity were studied on the concrete. The observations showed that the concrete with constant replacements of fly ash and silica fume and 30% bottom ash gave the optimum results to use.
