Yes. You can try this liquid 'Master Plaster MPCS 101' manufactured by Razon Engineering Company in your crushed sand /manufactured sand - cement mortar. If you contact them they will assist you with all the information and the product you will need.
The mix ratio of type 2 concrete is one part cement, two parts sand, and three parts pea gravel. You can also use sand or crushed stones in place of the pea gravel.

M 40 MIXING RATION SAND AND BLUE METAL CEMENT
Powdered limestone has to be heated with powdered clay to turn it into to cement. You can then use cement and powder it, then mix with water, sand crushed rock and a slow reaction takes place forming concrete. It is in the Cors Science GCSE
Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.
Concrete is made by combining cement, water, aggregates (such as sand and gravel), and sometimes additives or admixtures. The cement acts as a binder that holds the mixture together when it hardens, while the aggregates provide strength and durability to the concrete.
Limestone is used in making cement by being crushed and mixed with other materials like clay and sand. This mixture is heated in a kiln to create a powder called clinker, which is then ground into a fine powder and mixed with gypsum to make cement.
