The fineness of the original sand used in a concrete mixing plant

Concrete Mix Ratios - Cement, Sand, Aggregate and Water

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.

Evaluation of sustainable concrete produced with desalinated

Jun 01, 2017 · Since mixing reject brine with concrete can be environmentally beneficial by reducing demand for desalinated water, ground granulated blast-furnace slag (GGBS) can be mixed with concrete to avoid compromising the concrete durability (Nai-Qian, 1996, Ke-Feng and Pu, 1998). The use of GGBS has been shown to enhance the fluidity of concrete ...

What is Fineness Modulus of Sand (Fine Aggregate) and Calculation

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.
