Extensive reading (ER) is the process of reading longer, easier texts for an extended period of time without a breakdown of comprehension, feeling overwhelmed, or the need to take breaks. [ 1 ] [ 2 ] It stands in contrast to intensive or academic reading, which is focused on a close reading of dense, shorter texts, typically not read for pleasure.
"The Flesch–Kincaid" (F–K) reading grade level was developed under contract to the U.S. Navy in 1975 by J. Peter Kincaid and his team. [1] Related U.S. Navy research directed by Kincaid delved into high-tech education (for example, the electronic authoring and delivery of technical information), [2] usefulness of the Flesch–Kincaid readability formula, [3] computer aids for editing tests ...
Unlike regular concrete, ECC has a tensile strain capacity in the range of 3–7%, [1] compared to 0.01% for ordinary portland cement (OPC) paste, mortar or concrete. ECC therefore acts more like a ductile metal material rather than a brittle glass material (as does OPC concrete), leading to a wide variety of applications.
The deck of the Mihara Bridge, composed of bendable concrete, is only five centimeters thick and has an expected lifetime of one-hundred years. [ 2 ] Though HPFRCCs have been tested extensively in the lab and been employed in a few commercial building projects, further long-term research and real-world application is needed to prove the true ...

Materials science is an interdisciplinary field of researching and discovering materials. Materials engineering is an engineering field of finding uses for materials in other fields and ...
A living building material (LBM) is a material used in construction or industrial design that behaves in a way resembling a living organism. Examples include: self-mending biocement, [ 1 ] self-replicating concrete replacement, [ 2 ] and mycelium -based composites for construction and packaging .
Hempcrete is a construction building material that uses hemp shives, aggregate, water, and a type of binder to act as non-bearing walls, insulators, finishing plasters, and blocks. The material has low mechanical properties and low thermal conductivity, making it ideal for insulation material.
Polymer concrete is also composed of aggregates that include silica, quartz, granite, limestone, or other material. The aggregate should be of good quality, free of dust and other debris , and dry. Failure to fulfill these criteria can reduce the bond strength between the polymer binder and the aggregate.
