  • Concrete Mix Design Different Grades of Concrete

    Mar 31, 2018· To make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing. To know the Concrete Mix Design follow below:-

  • A promising future for manufactured sand

    When you are developing a concrete product with natural sand, opportunities for improvement are scarce. But with crushed sand, there are more opportunities: there is a wider range, and you can find the best fit for different types of concrete. A totally different hurdle is the acceptance of the use of crushed sand in the mix design.

  • What are the Materials for Replacement of Sand in Concrete

    The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.

  • Crushed Sand vs. Natural Sand: Make the Right Choice!

    Crushed sand can be of coarser and angular texture. This can lead to more water and cement requirement to achieve the expected workability. Crushed sand contains a larger amount of micro- fine particles. This can affect the strength of concrete.
