[PDF] THE EFFECT OF TRIETHANOLAMINE AND

The presence of finely ground limestone powder in concrete becomes more and more popular due to its ability to upgrade several properties of concrete. When the limestone powder(LP) is used in concrete in combination with triethanolamine (TEA) as an accelerator the hydration and hardening process of Portland cement is likely changed. This study reported the results of the authors’ research on ...

Effect of Limestone Powders on Compressive Strength

2020-1-9  to limestone powder at small particle size has a fineness higher than large particle size which results to more reactive. In addition, the small particle size can fill the pore between cement particles in paste that is known as a filling effect. Thus, the fineness of limestone powder used has influence on the observed compressive strength values.
