Effects of crushed stone dust on some properties of
Crushed stone dust acts as a filler in the concrete and contributes to reduce the absorption of concrete However, increasing the dust content more than 15% causes an increase in absorption which is a parallel leading with compressive strength The crushed stone used for testing all concrete samples was provided by Stevin Rock LLC quarry as a waste of producing gravel (coarse crushed stone) The crushed stone used for each mix was dry and stored in the same area The fineness modulus of the fine crushed stone from the source found to be 292 Fine crushed stone with different GRADING OF FINE CRUSHED STONE AND ITS EFFECT ON The Concrete has been traditionally made with use of Natural / River sand as fine aggregate As sand contributes to around 25 to 35% of total concrete along with coarse aggregates, cement water, the properties of the fine aggregates would be one of the major influencing factor in determining the fresh hardened Concrete Read More »Use of Crushed Stone sand its impact on Concrete Use of Crushed Stone sand its impact on Concrete

The effect of coarse crushed concrete aggregate on
The use of crushed concrete aggregates (CCA) (formerly referred to as recycled concrete aggregate (RCA)) is increasing, particularly for lowgrade applications, where quality is of less importance In higher value applications, such as structural concrete, further re has been required to understand the effect of coarse CCAs on the mechanical properties and durability performance Natural aggregates are products made of sand and crushed stone; and recycling aggregates are made mainly of crushed concrete and asphalt pavement (Goonan, 2000) According to the same author, natural aggregates corresponded to 36% of total The Environmental Impact of Recycled Concrete Portland limestone cement, river sand and quarry rock dust both of 2 mm maximum size as fine aggregate, and 14 mm crushed rock coarse aggregate were used for the concrete The particle size distribution and the physical properties of the fine and coarse aggregates are shown in Fig 1 and Table 1 respectively The fine and coarse aggregates satisfied the BS EN 12620:2002 + A1:2008 specificationsEffect of quarry rock dust on the flexural strength of
