Crushed Limestone Uses Benefits of This Natural Stone

Moreover,. Crushed limestone aggregates proved nearly 10 of high in strength compared to traditional gravels used in cementconcrete mixer. The strength comes from the angular shapes and sharp edges of crushed limestone aggregates compared to roundedshaped gravels obtained from natural resources, which formed through weathering processes.

Shape Wise Classification of Aggregates

Shape of aggregates can get influenced by not only the characteristics of parent rocks but also by the type of crusher used to crush the rocks. Most of the jaw crushers with plain jaws will give flaky aggregate, while with footed jaws will give cubical ore. But it is the cone crusher which will give perfectly cubical aggregates. Also Read:

Classification of Aggregates Based on Size

These materials include gravel, sand, or crushed stone mixed with water which is all added to the cement mixture to create concrete. The most common size of aggregate used in the concrete mix is 20 mm for coarse aggregate and particle size less than 4.75 mm for fine aggregate.

HOW AGGREGATE PROPERTIES AFFECTS CONCRETE Influence of Aggregate Properties on ConcreteChoice of AggregateAggregate QualitySand Or Fine AggregateAggregates influence the properties of concrete/mortar such as water requirement, cohesiveness and workability of the concrete in plastic stage, while they influence strength, density, durability, permeability, surface finish and colour in hardened stage.Aggregates are generally classified into two categories viz. natural and manufactured/processed.Geologically aggregates may be obtained from basalt, granite, limestone, quartzite, gabbro or schist rock etc. Main resources are igneous granite...The Effect of Aggregate Properties on Concrete

The shape and texture of aggregate affects the properties of fresh concrete more than hardened concrete. Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. Most natural sands and gravel from riverbeds or seashores are smooth and rounded and are excellent aggregates. Crushed
