The effects of limestone aggregate on concrete properties

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.

Magnesian Limestone Aggregate In Concrete Agg-Net

Crushed Magnesian limestone sands are suitable for use in concrete, especially those from?sources where the coarse aggregate absorption value is less than 4%. Sands from sources where the coarse aggregate absorption value is in the range 4–7% may also be acceptable in many circumstances, however an increased requirement for dust removal is

The use of limestone aggregate in concrete Universiti

Concrete structure is made up of cement, aggregate and water. In building construction the aggregates commonly used are limestone and granite. Three quarters of concrete is made up from aggregate, thus the selection of aggregate should be in the prime condition. To produce a good, strength and high quality concrete the materials used should be in accordance to standard specification.

2019-5-1  Crushed limestone aggregate concrete had reduced density compared to that with the normal concrete aggregates; a reduction in concrete density of up to 8.1% was observed when limestone in the sample mix M100 replaced 100% by weight of the coarse aggregate. This gives a significant reduction of the weight of the products and when used in
