... by volume, using both untreated ( UM ) and NaOH-treated ( TM ) rubber. Mechanical, durability, and microstructural properties were assessed through compressive and flexural strength tests, water absorption ( WA ), initial rate of water absorption ( IRA ), efflorescence testing, scanning electron microscopy...

... and durability tests, including compressive strength, flexural strength, rapid chloride permeability, water permeability, and ultrasonic pulse velocity, evaluated at 28 and 56 days. Results indicated that while both healing agents introduced moderate reductions in early mechanical strength, they significantly...

... of replacing cement with wollastonite in varying proportions ranging from 0% to 20%. It was found that a 15% replacement yielded a 28-day compressive strength of 37.89 MPa, nearly equal to that of conventional concrete. In addition, the incorporation of wollastonite improved the durability of the concrete mix...

...Shiv Sai Trivedi, MTech; Bibhuti Bhusan Das, PhD; Salim Barbhuiya, PhD This article presents a structured and comprehensive review of the existing literature on physical, chemical, microstructure, and durability properties of recycled aggregate concrete (RAC). The engineering properties of concrete...

... knowledge of the authors, this paper is the first study wherein NZ concrete has been evaluated using durability index methods. The NZ studied is presently not used as pozzolan in the local cement industry, hence its potential use in concrete would be new. In the investigation, concrete mixtures of 0.50...
