get the right concrete. the best concrete mix for making fake rocks from concrete is actually a mortar mix and not concrete at all. gravel is the main difference between a concrete mix and a mortar mix. for making fake rocks you will want a mortar that is free of larger aggregates like gravel.
concrete mix design:-concrete is a composite mixture which consists of cement sand and aggregate. concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. accurate concrete mix design makes concrete construction economical.
the results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.the compressive strength obtained is same as of normal mixes.in fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand.

this paper present the physibility of artificial sand in concrete for the purpose of experimentation concrete mixes are design for m20 and m25 grades by 0 to 100 % with increment of 20 %
concrete mix design is the process of economically proportioning of concrete ingredients (cement sand and aggregate) for better strength and durability based on the materials available at a
concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement sand and coarse aggregates. for e.g. a concrete mix of proportions 1:2:4 means that cement fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement two parts of fine aggregate and four parts of coarse aggregate.
from the above design results it can be observed that the strength of concrete increases with artificial sand. more over the presence of fines in artificial sand increases the workability and gives more sound concrete. the slabs using artificial sand are more leak proof than by river sand.
concrete is a construction material composed of :cement (commonly portland cement) as well as other cementitious materials such as fly ash and slag cement.aggregate (generally a coarse aggregate such as gravel limestone or granite plus a fine aggregate such as sand).
