In this paper, the correlation between limestone powder content and MB value in manufactured sand is analyzed and the effect of limestone powder content and clay content of manufactured sand on the MB value is studied, the results show that with the increase of pure limestone powder content, the MB values remained almost unchanged, and were less than 1.0; when the limestone powder content
Influence of Limestone Powder on Performance of the Pre-Mixed Cement Mortar. Article Preview. Abstract: Effect of the different contents of limestone power (LSP) in manufactured-sand (MS) is investigated in respect of the workability, setting time and compressive strength. The results show that the contents in a certain range can significantly
Limestone powder can be replacement with the cement content in SCLFC. Therefore, the aim of this paper is to determine the effect of limestone powder on SCLFC in term of flowability and compressive strength. The specimens were tested for compressive strength at 3, 7, and 28 days.
