concrete aggregate substitutes

  • Effect of oyster shell substituted for fine aggregate on ...

    Concrete elastic modulus decreases with SR of OS increase since elastic modulus of the OS is smaller than the elastic modulus of fine aggregate. The elastic modulus was reduced approximately 10% when OS of 20% is substituted for fine aggregate.

  • Can Concrete Be Eco-Friendly? - Green Living Ideas

    Concrete Alternatives. In addition to cement substitutes, there are other ways of making concrete more sustainable, based on two core environmental principles—recycle and reduce. These alternatives include: The use of recycled aggregate materials and preparations that results in reduced amounts of concrete needed to complete the job. Conventionally, cement was mixed with materials, such as sand or .

  • Can someone suggest an alternative of sand as a fine ...

    Knowledge Institute of Technology. Manufactured sand blended with natural sand in the ratio of 70:30 can be used as fine aggregate in concrete, which shows the better performance than conventional concrete. If the sand is replaced with manufactured sand, it performs as like conventional concrete. Fly ash also can be used as fine aggregate.

  • Solid vs. Aggregate Driveway | Home Guides | SF Gate

    Solid vs. Aggregate Driveway. Aggregate driveways are commonly known as exposed aggregate because the gravel (or stone chips, in some cases) in the concrete mix is partially exposed in the finished surface. Aggregate variations allow you to add color and texture to your driveway, creating an eye-appealing design that coordinates with your house...

  • How to Calculate Cement, Sand and Coarse Aggregate ...

    Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m3 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.
