TL;DR: An overview of advances in geopolymers formed by the alkaline activation of aluminosilicates is presented along with opportunities for their use in building construction as mentioned in this paper, with respect to fresh and hardened states, interfacial transition zone between aggregate and geopolymer, bond with steel reinforcing bars and resistance to elevated temperature.

TL;DR: A brief status of recycled aggregate concrete made from recycled aggregate, summarizes and critically analyses some of the most important research findings over the past few years regarding the material aspects is given in this article.

TL;DR: In this paper, apart from conventional weighting system, objective weight assignment procedures based on techniques such as artificial neural network (ANN), fuzzy set theory and combined neural and fuzzy set theories have been assessed for preparation of LSZ maps in a part of the Darjeeling Himalayas.

TL;DR: In this paper, the effects of nanosilica addition on hydration kinetics, microstructure refinement, fresh/hardened properties and durability characteristics of concrete are summarized.

TL;DR: Iron oxide-coated sand is a suitable adsorbent for reducing As(III) concentration to the limit (50 microg/l) recommended by Indian Standards for Drinking Water.
