Mix proportion for medium grade concrete with silica fume as cement replacement for general purpose construction

There are many demands of concrete in construction leading to the use industrial waste as mineral additive or supplementary filler improve performance and lower production cost. Silica fume is a distinct waste. The making silica made by case basis based on specific needs especially for prescribed High Performance Concretes. In this study, low/medium grade general investigated [1]. It an attempt find mix proportion with recommended replacement produce medium purpose construction. cement greatly increase mechanical durability properties concrete. 10% gives most practical percentage resulting 32% strength compared no fume. also possible normal using standard M40 proportion. Concrete samples less than did not show significant differences reference sample.
