1、 Limestone cliffs; limestone walls.

2、magnesian limestone

3、They were quarrying limestone.

4、limestone-gypsum handling system

5、Robeston Wathen limestone

6、wet limestone-gypsum scrubbing system

7、Cement is made from limestone.

8、Shearing strength of concrete and limestone and limestone is mostly controlled by cementation strength for concrete and limestone.

9、The Neoproterozoic Jiuliqiao Formation in Huainan region consists of sandy and silty limestone, stromatolite limestone and dolomitic limestone.

10、The limestone absorbs impurities from the ore.

11、vast cavernous chambers hollowed out of limestone.

12、sedimentary rocks,eg sandstone,limestone,slate

13、Rock, usually limestone, composed of oolites.

14、A magnesia-rich sedimentary rock resembling limestone.

15、Between the white limestone and the greyish pink limestone is a thin bed of clay.

16、There is a thin layer of clay between white limestone and gray limestone.

17、The grained Carbonate rocks of Qianjiang Formation in Qianjiang Sag can be divided into oolitic limestone, sand-clastic limestone, mud-crystal sand-clastic dolomite, alga-gobbet limestone etc.

18、Sulfuric acid eats away at limestone very aggressively.

19、There the soil is from weathered limestone soil or loess.

20、It's the deepest limestone cave in the U.S.

21、Yes, so there's two kinds of limestone caves.

22、We've said that sulfuric acid dissolves limestone, right?

23、Damingshan Limestone Mine is a main producer of flux limestone and metallurgical lime for Benxi Iron& Steel Company.

24、In manufacturing, limestone and clay are mixed first, and the composition of limestone can be matched arbitrarily, and then fired.

25、The Carboniferous limestone system are thin layers of limestone. Those which influence coal extraction are mainly single layers of limestone over 4m thick at the bottom of Taiyuan system.

26、When these creatures died, their shells fell to the bottom and gradually built up thick layers of limestone. For this reason, fossils are commonly found in much limestone.

27、By continuously recirculation the limestone slurry within the feed loop, the limestone slurry will be maintained at a fluid velocity within the piping sufficient to prevent plugging.

28、This shows that the best mixing proportion of limestone powder and cement may be determined through measuring the change of compactness of mixture of limestone powder and cement.

29、Abstract: The effects of added limestone contents in portland limestone cement and fineness of cement grinding on strength of the cement mortar were investigated.

30、Combining with practices, this paper analyzed private mining situation of limestone, and set forth some opinions and countermeasures in view to the development of limestone mining.
