# mix ratio m grade concrete per m Solutions Just Right For You

However a mix with a ratio of 0 35 may not mix thoroughly and may not flow well enough to be placed More water is therefore used than is technically necessary to react with cement Water–cement ratios of 0 45 to 0 60 are more typically used For higher-strength concrete lower ratios are used along with a plasticizer to increase flowability When cement sets it produces 100 calories per gram so that the temperature of a structure may rise 135 degrees Certain fly ash can be used to keep the temperature from rising too high (less than 45 degrees) However concrete with fly ash can set up normally or even rapidly since many other factors control the set and strength development Freeze-thaw durability may not be acceptable with

Concrete Mixed Design Method (BS Method) Concrete Mix Design Finalize the proportions of concrete mix constituents (Cement Fine aggregate (or normally Sand) Coarse aggregate and Water) Produce concrete of specified properties Figure 1 Concrete Mixer – Drum type 140L Concrete Mix Design procedure The method of concrete mix design applied here is in accordance to the method

While sand is the most common aggregate used to create concrete you can also mix cement with gravel crushed stone or even pieces of old concrete The key to success will be the ratio of the mixture The basic equation for making concrete is 60 to 75 percent aggregate material (sand or the other aggregates mentioned) mixed with 10 to 15 percent cement The amount of water you mix in will

Corrections are to be made in the mix design for different zones of sand and maximum size of coarse aggregates To do this a reference mix as per IS 10262-1982 has been considered and rheological parameters of this reference mix were obtained with the present rheometer The reference mix is follows 53 grade OPC = 571 kg/cu m

## Influence of filler type on the properties of foam concrete

As the foam is added to the wet foam concrete mix the consistency of the wet mix is very important to get the design density Fig 2(a) and (b) show the variation of density ratio (measured fresh density divided by design density) with water–solids ratio for mixes with different filler type for each of the design densities viz 1000 and 1500 kg/m 3 respectively

What is Plum Concrete? In some mass concrete foundations boulders of say 150 mm size up to 30% of the total quantity of concrete are mixed in the wet concrete This adds to economics and saves heat generation Such concretes are called plum concretes After at least two layers of wet concrete is completed well-shaped []
