Jun 18, 2018· If I wanted to make it stronger, I'd take an old kitchen measuring cup and add 16 ounces of Portland cement and eight ounces dry measure of hydrated lime to each bag of concrete. AD

A properly designed mixture possesses the desired workability for the fresh concrete and the required durability and strength for the hardened concrete. Typically, a mix is about 10 to 15 percent cement, 60 to 75 percent aggregate and 15 to 20 percent water. Entrained air in many concrete mixes may also take up another 5 to 8 percent.

Concrete

Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes.

Soil-cement is a mixture of Portland cement, natural soil, and water used to form a hard, semi-rigid paving surface.It is most often used in highways or as a sub-base for asphalt or other forms of paving, but it can also be used as a cheap stand-alone paving surface .
