Also Abrams' water-cement ratio law. A law which states that the strength of a concrete mix is inversely related to the mass ratio of water to cement. As the water content increases, the strength of the concrete decreases. abrasion The process of scuffing, scratching, wearing down, marring, or rubbing away a substance or substrate. It can be intentionally imposed in a controlled process using ...
The BQM-167 was developed and manufactured by Composite Engineering Inc. (now part of Kratos Defense & Security Solutions), and is constructed of carbon fiber and epoxy-based materials. [1] [3] Two prototype targets were built and test flown in 2001. The BQM-167A was selected as the next-generation Air Force subscale aerial target in July 2002.
Earthquake engineering – is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. Earthquake-resistant structures – Earthworks (engineering) – Edge jointing – Endurance time ...

The Construction Specifications Institute (CSI) is a United States national association of more than 6,000 construction industry professionals who are experts in building construction and the materials used therein. The institute is dedicated to improving the communication of construction information through a diversified membership base of ...
Heavy construction equipment is usually used due to the amounts of material to be moved — up to millions of cubic metres. Earthwork construction was revolutionized by the development of the scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.
