Artificial Sand

The mixed sand fineness modulus is not less than 18, and the ultra-fine sand fineness modulus is not less than 09 C60 or more The mixed sand should pass through the test to obtain reliable data and can be used after it has been demonstrated that the performance requirements are met the requirement...

THE ROLE OF FINENESS MODULUS

Jul 20, 2018· Fineness modulus also provides important information about the density of the resulting concrete, as well as its compressive strength Both of these factors must be taken into consideration when designing the concrete For more information about the role played by fineness modulus, contact the concrete experts at Southport Concrete Corp...
