Abstract: Concrete has a broad task to carry out in both development and improvement of structural buildings and foundations. Based on its mass occupied per unit volume it can be classified as lightweight, ordinary or heavyweight concrete, each having its own unique applications. Heavy weight or high density concrete offers dependable, cost-effective radiation protecting and can be utilized as protective materials to amplify security in the accessible space. Generally unit weight more than 2.6 t/m3 is classified as high density concrete. Densities as high as 6 t/m3 is also referred in literature. Apart from the variety of uses discussed, this investigation focuses on the use of high density concrete using iron ore for the productions of counterbalances utilized in washing machines. These counter balances are known as ballasts. These act as stabilizers in washing machine and require a definitive weight in other words deliver desired weight in a given volume. High density aggregates are the key ingredients in its production. Other aggregates used to accomplish the required densities are Haematite, Limonite, Magnetite and Steel. Haematite with density varying from 3.4-3.6 t/m3 is used in the present study. Efforts are made to maintain desired density of 3.1 t/m3 by carrying out Mix design to accomplish a minimum compressive strength of 35 N/mm2 in just seven days of curing.
