Optimising the Workability and Strength of Concrete Modified with Anacardium Occidentale Nutshell Ash

Fibers, 2021
Strength failure persists both in structural and mechanical analysis. One of its prominent characteristics is the adequate provision for parameters that minimise or maximise strength objectives while satisfying boundary conditions.

Effect of Water Magnetization Technique on the Properties of Metakaolin-Based Sustainable Concrete

Construction Materials, 2023
Using metakaolin (MK) in concrete with magnetized water (MW) has a high possibility to enhance concrete suitability. In this study, the effect of using MK and MW on concrete characteristics was studied through testing twelve concrete mixes.

Rheology and workability of SCC

, 2023
ACI 237 Committee report (2007) defines the self-compacting concrete (SCC) as the "...highly flowable, non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation" (.

The Effect of pH on the Workability of Concrete [PDF]

, 1952
It was believed that the pH of concrete would affect the workability. The effect of pH on the workability was determined experimentally by adding chemical admixtures to a cement mortar mix, measuring the pH and workability.

Influence of a Multifunctional Admixture on the Workability and Mechanical Properties of Gypsum-Sand Mortar [PDF]

E3S Web of Conferences
Gypsum-based mortars are common building materials, but their use is limited by low mechanical strength and an exceptionally rapid setting time. This study investigates the effects of a multifunctional, calcium carbonate-based powder admixture on a ...
