Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel

At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower waterratio than the smaller sizes. 3.

May 10, 2017· For example, M20 grade of aggregate will have a higher A/C ratio than of M30; Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio. The same is governed by particle size and shape of aggregate used.

You can often save money by selecting the maximum allowable aggregate size. Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the watercement (w/c) ratio is kept constant.

Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well as cement and water requirements, workability, pumpability, and durability of concrete. In general, if the watercement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength.

Note: General ratio of fine aggregate to coarse aggregate is 1:2, but it can be adjusted between 1: to 1: based on the grading of fine aggregate and size of coarse aggregate. Let’s find out the quantity needed to produce M20 grade by the codal procedure. Sand is confirmed to Zone II – average grading. The ratio of fine to coarse aggregate is chosen as usual as 1:2.

In soil mechanics, the void ratio describes the relationship between the volume of voids, or spaces, in the soil or aggregate to the volume of solid constituents, or grains. Algebraically, e = Vv /Vs, where e represents the void ratio, Vv represents the volume of voids and Vs represent the volume of solid grains.
