Jan 29, 2014· In addition to the value of limestone slabs quarried for building materials, limestone is also used in cement. A discussion about cement requires a distinction between cement and concrete: although the two terms are often used interchangeably.
Lower-grade limestones, particularly ones with some clay content, can be used in the production of cement for use in the building and construction industry. Cement is a key ingredient of concrete, huge volumes of which are poured each day to serve as roading, foundations, structural beams and columns.
There still seems to be some confusion about whether fine limestone in cement (up to about 5% as permitted by eg: US and European standards) is an inert filler, or whether it is chemically reactive and contributes to the cement hydration products.
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.
Making Concrete – Concrete is a combination of cement, water, sand and crushed aggregate. In some cases, contractors will choose to utilize crushed limestone as the aggregate material in order to create an attractive, durable concrete product.
