Sodium and Magnesium Sulfate Resistance of Mortars with Interground Limestone and Limestone Powder Replacing Cements

The Use of Limestone in Portland Cements: Effect on Thaumasite Form of Sulfate Attack

Studies on Main Properties of Ternary Blended Cement with Limestone Powder and Microsilica

The ternary system of Portland cement-microsilica-limestone has been studied by investigating its set and strength behaviours. A number of different cementitious <span style="font-size: 10pt; color: #0...

Limestone and Silica Powder Replacements for Cement: Early-Age Performance.

Developing functional concrete mixtures with less ordinary portland cement (OPC) has been one of the key objectives of the 21st century sustainability movement. While the supplies of many alternatives to OPC (such as fly ash or slag) may be limited, those of limestone and silica powders produced by crushing rocks seem virtually endless. The present study examines the chemical and physical influ...

Effect of Limestone Powder on Microstructure of Ternary Cementitious System

The pressure to reach sustainability favours the development of ternary composite cement. The synergistic effect on mechanical behaviour at 28 days between limestone powder (LP) and pozzolanic additives, i.e. fly ash (FA) and blast furnace slag (BFS), has been documented. In order to better understand the synergistic effect, this article investigated the effect of LP on the microstructure of PC...

Mine water treatment with limestone for sulfate removal.

Limestone can be an option for sulfate sorption, particularly from neutral mine drainages because calcium ions on the solid surface can bind sulfate ions. This work investigated sulfate removal from mine waters through sorption on limestone. Continuous stirred-tank experiments reduced the sulfate concentration from 588.0mg/L to 87.0mg/L at a 210-min residence time. Batch equilibrium tests showe...
