Too much water makes your concrete prone to segregation and a weakened surface called "bleeding." This causes discoloration and uneven curing. Too little water also hinders cement's hydration, affecting color. Monitoring slump tests and sticking to the recommended water ratio for a mixture's design avoids this issue. Adjust the water in ...
Why 2,000 Year-Old Roman Concrete Is So Much Better …
Modern concrete is typically made with portland cement, a mixture of silica sand, limestone, clay, chalk and other ingredients melted together at blistering temperatures. In concrete, this paste binds 'aggregate' - chunks of rock and sand.
How to Make Concrete Floors Shine | Hunker
Polished concrete flooring that has chips, dips and dents needs a lot more help than a pass with a concrete smoother machine. Fill any divots or snaking cracks with an epoxy concrete filler. If the cracks are wide, you'll need an epoxy with a hardener and sand to ensure the stability of the concrete flooring.

Various chemicals, called admixtures, can also be added to concrete to make different sorts of …
Concrete: Scientific Principles
If the aggregate makes the concrete unworkable, the contractor is likely to add more water which will weaken the concrete by increasing the water to cement mass ratio. Time is also an important factor in determining concrete strength. Concrete hardens as time passes. Why? Remember the hydration reactions get slower and slower as the tricalcium ...
The Science Behind Concrete and Why it Matters for Pros
Water Makes Concrete "Work" Cement is mostly limestone that's been ground up and superheated. Adding water causes a chemical reaction; microscopic crystals develop, grow and interlock, binding the aggregate together and forming a rock-hard mass.
