This paper presents the production of enviromental concrete using fine aggregate and fly ash to reduce bad influences on environment. The excessive exploition of traditional sand in Mekong Delta rivers has recently caused serious landslides sweeping away a large area and making. Therefore, using alternative materials - fine aggregate to replace river sand - is very important and urgent.

Abstract - In order to avoid using natural river sand. An alternative material is proposed to the strength of the concrete by replacing of fine aggregate. Partially by waste material like copper slag which is an environmental waste. To make us of these material without sace the strength and durability of the concrete structure. To strength is measured by use of non-destructive and ...

Use of Quarry Dust to Replace Sand in Concrete ... the most common source of fine aggregate. Now-a-days the natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete ...

Making good quality concrete with finest sand (grading zone –IV as per Indian code IS:383-1970) is itself a challenge, moreover there is unavailability of natural coarse aggregate locally. Therefore, in this paper a concerted effort has been made to check the feasibility of use of brick aggregate made of locally available brick in standard concrete (M25 to M55 as per IS:456-2000). High water ...
