(727h) Utilization of Marble Dust As a Concrete Additive to Enhance Its Properties

With the advancement in the building technology, each and every step to alter the cement properties for making it environmentally beneficial and equally strong is important. In this advancement, one always opts for an alternative which provides the strength to the building by reducing its cost and weight.

Marble often known as calcium carbonate (CaCO₃) has been a well known material used as a building material since the ancient times. Marble is often available in combination with Silicon Oxide (SiO₂), Aluminum Oxide (Al₂O₃), Iron Oxide (Fe₂O₃), Magnesium Oxide (MgO) and Calcium Oxide (CaO).

Marble is utilized at a number of operations and the waste obtained requires an extra effort for the adequate environmental disposal. The waste marble left in the environment can be harmful therefore must be utilized for an alternative process to reduce its harmful effect. The addition of marble dust to concrete is proving to be an effective alternative for the process. The process of marble addition is participating in the hydraulic reactions contributing significantly to the composition and microstructure of hydrated products. Another way of utilizing the marble dust is to utilize it in the geo-polymer concrete which will be strengthening the concrete properties.

The entire paper is evaluating the utilization of the marble dust in concrete so that the unsafe waste of marble is used and fewer efforts is to be taken for its disposal and also to accomplish viability, economy and environmental conservation.
