dc.description.abstract | In this study limestone powders with different particle sizes of 1.6 and 4.5 (m were ust'd to replace a part of Portland cement in different replacement levels to produce Portland-limesPne cement pastes. The percentages of limestone replacement are 0, 5, 10, 15 and 20% by weight. The effect of fineness and the amount of limestone powders on compressive strength and set¬ting time are investigated. It has been established that limestone replacement causes reduce the compressive strength due to the dilution effect. The fineness of limestone powder used has influ-ence on the observed compressive strength values. Both initial and final setting times were increased with an Increase in the amount of limestone. Furthermore, at the same level replace¬ment the cement pastes using 1.6 pm of limestone show lower setting time than that using 4.5 pm, respectively. | vi_VN |
