Bioactive glass ionomer cements (GICs) have been in widespread use for ∼40 years in dentistry and medicine. However, these composites fall short of the toughness needed for permanent implants.
Engineers have developed a new test that can predict the durability of cement in seconds to minutes -- rather than the hours it takes using current methods. The test measures the behavior of water ...
Researchers have developed a nondestructive and noninvasive optical technique that can determine the setting times for various types of cement paste, which is used to bind new and old concrete ...
Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...
Cement production contributes an estimated 6% of global greenhouse-gas emissions, say scientists who are trying to chip away at the pollution problem. Two start-ups, one in Canada and another in ...
The tricky process of sealing an offshore oil well with cement — suspected as a major contributor to the Gulf of Mexico disaster — has failed dozens of times in the past, according to an Associated ...
