Mineral Admixtures : The Key To High Strength Concrete

Use of Mineral Admixtures in Concrete

Performance of Pozzolanic Concrete Using Different Mineral Admixtures

Concrete is probably the most extensively used construction material in the world. However, environmental concerns regarding rapid consumption of natural resources and CO2 emission during cement manufacturing process have brought pressure to reduce cement consumption by the use of cement replacement materials (CRMs). The utilization of calcined clay (metakaolin) and silica fume in concrete has ...

Production of High Performance Concrete Using Admixtures

In this study, it is aimed that production of high performance concrete using admixtures. The admixture is used to resist against to freezing of concrete, and concrete (C20) is produced, and cured in water. 8 samples are tested in pressure, and mean stress is determined as 28 MPa. Remaining two samples are tested with image processing technique, and determined that sample which containing an ad...

Properties of Self-Compacting Concrete with Machine-Made Sand and High-Volume Mineral Admixtures

Based on appropriate assessment methods and indexes of self-compacting concrete proposed, properties of concrete made with river-sand and machine-made sand was firstly compared in different mix proportions. The techniques such as basic parameters optimization of mix proportion, admixture composition, large-volume mineral admixtures addition for preparing machine-made sand self-compacting concre...

Effects of Different Mineral Admixtures on the Properties of Fresh Concrete

This paper presents a review of the properties of fresh concrete including workability, heat of hydration, setting time, bleeding, and reactivity by using mineral admixtures fly ash (FA), silica fume (SF), ground granulated blast furnace slag (GGBS), metakaolin (MK), and rice husk ash (RHA). Comparison of normal and high-strength concrete in which cement has been partially supplemented by miner...
