Concrete is stronger than cement.It is composed of aggregates (sand and gravel) and cement; and may be cast with reinforcing bar within it (reinforced concrete). Cement is only a part of concrete. Cement has no tensile strength while concrete has compressive and tensile strength.
162. Comparison Of Quantities Of Materials - The mixture of concrete used for this class of work is often 1 part Portland cement, 3 parts sand, and 6 parts stone. The quantities of materials required for one yard of concrete (www. books.google.com) ("Cement and Concrete") 495. The concrete was one part Portland Cement; three parts sand; three parts gravel and three parts broken stone. (www.books.google.com) ("Cement and Concrete")
You would have: 1 part cement 5 parts of Ballast (Sand, gravel mix) And then add water till you get the disired mix quality
Small amounts of concrete can be easily mixed in a wheelbarrow with a spade but larger amounts might require a concrete mixer. Towable concrete mixers, both electrical and mechanical (petrol) can be hired from hire plant depots. Mix in the wheelbarrow or concrete mixer, cement, gravel, sand and water. For general purpose concrete the mix can be 1 part cement, 2 parts sand and 3 parts gravel. Most cement bags will have mixture recommendations written on the bags. The mixture of cement, sand and water is going to vary depending on the planned use of the surface.
Please note that a key correction in terminology is essential before your question can be answered: use the word "concrete" instead of "cement." The answer is to modify your mix (i.e. Portland cement, sand, gravel, and water) by using hydraulic cement to repace part of the Portland cement. The higher the amount of hydraulic cement you add, the quicker the setting time and the impermeability. However, hydraulic cement sets so quickly that you have limit the amount of total mix so as to be able to pour it and form it before it sets.

It's made up from partially cement

when concrete is vibrated while pouring in to the form work, the cement slurry part tends to get drained through voids between aggregates and the richest part of cement slurry is detained at bottom portion of column. this causes a strong, dense, and void free concrete which ensures better compressive strength than the concrete on top portion of column.
The correct spelling is cement (concrete, glue, or verb to firmly join).
The ideal ratio for a sand and cement mix for a strong and durable concrete foundation is typically 3 parts sand to 1 part cement.
The ideal cement and sand mix ratio for optimal strength in a concrete mixture is typically 1 part cement to 3 parts sand. This ratio helps ensure a strong and durable concrete mix.
The recommended mix ratio for Portland cement in concrete is 1 part cement, 2 parts sand, and 3 parts gravel or crushed stone. This ratio helps to achieve optimal strength and durability in the concrete.
The recommended sand to cement ratio for optimal strength in a concrete mix is typically 2:1. This means using two parts sand for every one part of cement.
The ideal cement to sand ratio for achieving optimal strength in a concrete mixture is typically 1:2, meaning one part cement to two parts sand. This ratio helps ensure a strong and durable concrete mix.
