Limestone filler cement in low w/c concrete: A …

The effect of limestone filler (up to 20%) on the degree of hydration, the volume of hydration products, and the optimal replacement of limestone filler in cement pastes at different w/cm ratios (0.25–0.50) were investigated by using a quadratic statistical model. The results show an increase in the degree of hydration in very low w/cm ratio paste when the limestone filler content is ...

This experimental study aims to determine the effect of limestone filler on concrete expansion due to delayed ettringite formation (DEF). Different mortars made with different sizes and percentages of limestone filler and Portland cement CEM I 52.5N are cured in water. The expansion of the specimens is measured. Results show that DEF is not inhibited by limestone filler.

Effect of limestone filler on the sulfate resistance …

After 360 days of sulfate immersion, the results indicate that the 10% of limestone filler replacement shows no significant effect on sulfate performance of these cements, whereas 20% of limestone filler (LF) causes detrimental effects on sulfate durability. This behavior can be explained by the changes in the hydration degree, capillary porosity, and type of hydration products produced by LF ...

Effect of limestone filler as mineral addition in self ...

Limestone filler is regularly used as mineral addition in self-compacting concrete (SCC). Besides the normal cement content (around 300 kg per m³ of concrete), limestone filler is added in quantities of 200 to 300 kg per m³ of concrete. Because of the fundamentally new concept of SCC, the structure of the material, as a result of the hydration process, can show some differences compared to ...

ADDITION OF LIMESTONE IN THE LOW HEAT PORTLAND CEMENT …

To discuss the effect of limestone on the physico-mechanical properties of low heat Portland cement, the attention must be paid to whether it is a substitution of the gypsum or an addition to the clinker. Not all clinkers accept the same percentage of limestone; it depends considerably on the fineness and the composition of the cement, i.e. the reactivity of the clinker [1]. The effect of ...
