= Weight of bitumen in the mix 1 = Weight of coarse aggregates in the mix 2 = Weight of fine aggregates in the mix 3 = Weight of filler in the mix = Weight of the bitumen in the mix 5.4.4.3 Effective bitumen content in the bituminous mixes by volume (V be)
Second-generation recycled concrete aggregates (second RCAs) prepared by crushing waste RAC can further promote the sustainable development of the construction industry, in which the mix-proportion design method of RAC used in different environments is key in determining the feasibility of recycling second RCA.
The M30 concrete mix ratio is a proportion of ingredients used to achieve a particular strength in concrete. The ratio is 1:0.75:1.5, which means for every 1 part cement, you need 0.75 parts sand and 1.5 parts aggregates when making 1 cubic meter of concrete Concrete Mix Design IS Code. For Concrete mix design, we use, IS 456, and IS 10262.
Due to the complex component of coarse aggregate used in mixed recycled aggregate concrete (MRC), the conventional mix design method is not suitable for MRC. The increase of coarse aggregate heterogeneity, larger total mortar volume of MRC, and the weaker strength of CRA and BRA are the primary differences between MRC and natural concrete (NC).

The percent of coarse aggregate to concrete for a given maximum size and fineness modulus is given by Table 6. Coarse aggregate ...
A concrete mix is a combination of five major elements in various proportions: cement, water, coarse aggregates, fine aggregates (i.e. sand), and air. Additional elements such as pozzolanic materials and chemical admixtures can also be incorporated into the mix to give it certain desirable properties.
Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structures. So, concrete mix design can be stated as Concrete Mix = Cement:Sand:Aggregates.
