Eco-friendly—the material is so durable, it could literally last a lifetime—concrete is also a recyclable material. At its most basic, a concrete mix consists of sand, rock and cement, which makes it more a more sustainable option than other countertop materials (think granite or marble) that are mined, non-renewable materials.
Whether you hand mix concrete in a plastic tub, homemade mixing tub or wheelbarrow, the technique is the same to find the right concrete mix ratio. However, it's easier to move and dump concrete that's mixed in a wheelbarrow. For larger jobs, you could rent a mixer ( per day), but it may be more economical to simply order ready-mix concrete.
Direct Colors Stains create permanent color effects in concrete, gunite, cement plaster, stucco, shotcrete, natural stone marble, cultured stone, limestone and other surfaces. Once sealed with a clear or tinted concrete sealer, the color effect unique to each stained surface will last for years to come. Direct Colors Concrete Dyes are ideal for color accents and stain repairs.

Mixing concrete by hand. Generally in the UK, we hand mix concrete 'on the deck', either using a slab of existing concrete (which can be hosed off and cleaned down afterwards) or on a large mixing board. In other countries they seem to prefer to mix in a barrow or tub - (seems awkward and harder work to me!).

The density of the plain concrete will vary between 2200 and 2500 Kg/meter cube. The compressive strength is 200 to 500 kg/cm 2.. These types of concrete are mainly used in the construction of the pavements and the buildings, especially in areas where there is less demand of high tensile strength.
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
