THE USE OF LIMESTONE AGGREGATE IN CONCRETE

2017-6-15  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. JKR standard specification for building works mentioned that the use of limestone is limited to super structure only whereas for substructure granite aggregate should be used. Due to this problem statement this study is carried out to investigate whether chemical attack in limestone aggregate is the source of problem for sub structure (concrete structure below ground level). This study involved in testing of limestone and granite aggregates. The scope of study includes the investigation on the strength, bonding and chemical attack in the concrete. The main objective of the research is to study the properties of lime stone

Salt Weathering of Limestone Aggregate and Concrete ...

Kansas aggregates are frequently alkali reactive or subject to Dcracking when used in concrete. The use of deicing salt, usually halite (NaCl) in Kansas, makes those problems worse. Salt allows the concrete to become wet and to stay wet longer, increasing the time for reactions to occur. Clays in limestone aggregates have been altered by deicing salt solutions remaining in the aggregates.Degraded illite changed to sodium montmorillonite. Quartz has been altered by electric currents induced in the concrete. Some quartz took on an optical property, undulatory extinction, that is frequently associated with potential alkali reactivity. Salt (NaCl) scaling of concrete blocks and slabs without freeze-thaw has been observed. Monitoring salt water movement through the walls of concrete cups has provided insight on how and where salt water moves in concrete. The salt water movement and deposition of salt crystals has caused considerable scaling of both the cement paste and the limestone aggregates of the concrete. The salt "gnaws away" or corrodes the limestone aggregate

This low compressive strength value is believed to be due to the presence of high sand and mud content in the lithic conglomerate aggregate.
