TL;DR: The concrete industry is known to leave an enormous environmental footprint on Planet Earth as discussed by the authors, which contributes to the general appearance that concrete is not particularly environmentally friendly or compatible with the demands of sustainable development.

TL;DR: In this article, the authors reviewed the characteristics of copper slag and its effects on the engineering properties of cement, mortars and concrete and investigated the use of slag in the production of concrete as raw materials for clinker, cement replacement, coarse and fine aggregates.

TL;DR: In this article, the use of crushed waste glass as aggregate for concrete products was investigated, and it was shown that waste glass ground to U.S. standard sieve size No. 50 or smaller causes mortar bar expansions in the American Society for Testing and Materials C 1260 test of less than 0.1%.

TL;DR: In this article, a theory for an enhanced mathematical model of R/C frame members is presented and its accuracy is verified by simulating various laboratory experiments for which data were available in the literature.

TL;DR: In this paper, the degradation mechanisms of natural fiber in the alkaline and mineral-rich environment of cement matrix are investigated by designing a contrast test to embed sisal fibers in pure and metakaolin modified cement matrices.
