2014-1-29 To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

2010-12-1 The use of limestone in the construction industry has been increasing due to benefits as aggregate. Some of these benefits include good strength, low possibility of alkali-silica reaction and the decrease in drying shrinkage in concrete. This research discusses the consumption and general characteristics of the limestone aggregate in USA and Japan.

This research deals with the field investigations and construction properties for using limestone as a lightweight course aggregate in concrete mixture in stead of normal coarse aggregate. Concrete cubes samples have been prepared with dimensions of 150*150*150 mm according to ASTM. For these samples the normal coarse aggregate was replaced by 100% coarse crushed limestone.

2017-8-1 Limestone is one of the key minerals used in cement making. Limestone is a sedimentary rock composed mostly of the calcium carbonate (CaCO 3) and, according to the Mineral Education Coalition, comprises about 15% of the Earth’s sedimentary crust. Surface mining is the general excavation method. There are a few underground limestone

2015-8-20 I have a lot of limestone screening left, I was thinking of making my own concrete mixture using Portland cement, limestone screening and Sand, and throw in some concrete fibers. I looked online and I haven't seen anyone doing this, people usually use gravel. the limestone screening is less than 1/4" in size, its most likely 1/8" in size.
