Cement hydration. By the process of hydration (reaction with water) Portland cement mixed with sand, gravel and water produces the synthetic rock we call concrete. Concrete is as essential a part of the modern world as are electricity or computers. Other pages on this web site describe how PC is .

Examples of the scientific method. If possible, an experiment is set up that allows more accurate measurements than those leading to the preliminary inference. Such a test is provided by a ball rolling in a curved channel so that its centre traces out a circular arc of radius r, as in Figure 3.

Progressive idealization ("concreteness fading") allows originally grounded and interpretable principles to become less tied to specific contexts and hence more transferable. Citation.

These drying shrinkage cracks cause the surface to be susceptible to aggressive fluid ingress creating concrete durability problems such as corrosion, salt damage, or freezethaw damage," said Yaghoob Farnam, PhD, an assistant professor in Drexel's College of Engineering and principle investigator of .

In passive solar design, heat is absorbed in the building's thermal mass. The object with thermal mass is usually a dense material like a cement, tile, stone or water. Objects with this ability to conduct heat are usually located in the floor or walls of the building.

Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories. The scientific community accepts and uses such explanations until displaced by better scientific ones. When such displacement occurs, science advances. Science advances through legitimate skepticism.
