Mixing Process And Strength Properties Of Concrete Classification

Concrete Class - Mixing + Pouring Concrete - Instructables

With the right amount of water this reaction makes very strong concrete - too much or too little water will weaken concrete. Hydration process is slow, taking concrete a full 28 days to reach it's full strength potential. Luckily, concrete is hard after about a day and can be safely handled without damaging the surface after 48 hours.

Nov 15, 2015 · A concrete mixer as shown in Fig. 2 (also commonly called a cement mixer) is a device that homogeneously combines cement with aggregates such as sand or gravel and water. A typical concrete mixer uses a revolving drum to mix the components. Internal blades are arranged in such a manner to lift and tumble the ingredients and direct the concrete into the circulatory path.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past, limebased cement binders, such as lime putty, were often used but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...
