What is the Difference Between Lime and Limestone? Lime is a versatile chemical with many uses. It is vital in the production of countless materials. Lime, or calcium oxide (CaO), is derived from high …
The use of limestone powder as cement replacement has reduced the ultrasonic pulse velocity of specimens. The lowest value of ultrasonic pulse velocity is related to the specimen containing 30% limestone powder (C-30-0). So that the ultrasonic pulse velocity of this specimen is about 7% and 10.2% less than the ultrasonic pules …
According to the Chinese standard for construction sand, the highest limit value of stone powder content in sand and gravel is 10 % [6].But after grinding the stone powder finely.Its mechanisms of ...
The results show that limestone powder can react with cement but its reaction degree is very low even at 5 years. The addition of limestone powder tends to …
recycled concrete powder (RCP), marble powder (MP), glass powder (GP), and limestone powder (LP) as viable substitutes for traditional cement, at varying rates of 25%, 30%, and 35%, with the overarching goal of augmenting sustainability in construction practices. The outcomes of the experimental investigation unveiled signicant insights.

The objective of this study is to investigate the performance of normal- and high-strength concretes including limestone powder (LP) through their mechanical properties. Moreover, sustainable flat plates made of these concretes were investigated through their punching strength. For this purpose, two different types of concrete (normal …
The high expansive clay was treated by different percentages (6%, 12%, 18%, 24%, 30%, and 36%) of limestone powder. The results indicated that the geotechnical properties could be improved by using limestone powder. Also, the optimum percentage of limestone powder that can be added to expansive soil is recommended.
The amount of limestone powder has only a minor effect on structural build-up and static yield stress and thus, on buildability. However, we find a general strong increase in static yield stress during pumping of LAC, which further facilitates the buildability in addition to the positive effect of the low density of LAC resulting in reduced ...
In this study, we focused on the effects of fineness and content of the quartz powder on carbonation curing for cement-quartz powder binary mixtures and compared …
