Another type of mix was prepared by adding a range of crushed cockle shell ...
GET PRICEThe practice of sustainability in construction occupies an increasing prominent position in order to preserve the environment. Considering the environmental impacts caused by waste generation, the use of PET bottle flaks and crushed sand in partial substitution of conventional sand used in concretes is proposed. The aim of this work was to formulate concrete compositions with 1:3 and 1:4 ...
GET PRICEConcrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

GET PRICECrushed concrete costs $11 to $53 per ton, around $16 to $75 per cubic yard, and $1 to $3 per cubic foot, with prices depending on the quantity. Leftover concrete and broken asphalt get crushed and recycled, which is a cheaper and more eco-friendly solution for gravel driveways. Recycled concrete aggregates last as long as natural stones.
