GRADATION OF AGGREGATE FOR CONCRETE BLOCK

The fineness modulus of the aggregate grading is an excellent gage of the aggregate gradation. Some researchers have found that an optimum fineness modulus exists for any particular aggregate. A theory of inter-particle voids has been used in explanation of the optimum fineness modulus.

Peat, Sand, Perlite | ICPS - International Carnivorous Plant

Do NOT use play sand, plaster sand, or builders sand straight. Pool filter sand is too fine. The fine particles will make the soil mix like concrete. You are better off not using sand at all if you can not get the right sand. Perlite is a good alternative to sand but it has drawbacks. In some areas it is hard to find perlite that is not salty.

What is Fineness Modulus of Sand (Fine Aggregate) and

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus. Fine aggregate means the aggregate which ...

Cement vs Concrete Different Test, Type & Uses

7/16/2019 · While concrete is a mixture of many material like cement, sand, aggregate and water. Cement is used with other material while concrete is already mixed. Concrete is used for making RCC, DPC, PCC and filling many other holes of building, while cement is very thin paste so only used for concrete making or for making of cement plaster.

Fineness Modulus - an overview

The appropriate range of fineness modulus of the sand aggregate used in normal concrete is 3.7–1.6. Both medium sand and coarse sand spiked with some fine sand (coarse:fine = 4:1) are applicable. Sand aggregate plays a significant role as a skeleton and in passing the stress in concrete.

Mechanical and Durability Properties of Concrete Made with

The FS substitution rate was varied between 10% to 50%, in increments of 10%. FS was washed with fresh water more than four times before it was used in the concrete to remove the ashes and clay particles. Then it was dried in atmospheric sunlight for the duration of two days and then used in concrete mixtures.
