The replacement amount of fine aggregate substitutes varies with rivers' 0255075. The research shows that the quarry dust has the characteristics of fine aggregate, and the dust of 50 quarries can be replaced in sand to produce the best strength of concrete. 25 the strength value of the mixture can be obtained by replacing stone powder with fine aggregate.
When fine aggregate is replaced from 10 to 0 in quarry dust, the splitting tensile strength decreases by 3. The increase of compressive strength mainly depends on the percentage of quarry dust, because it has high ozone activity. 4 the workability of concrete increases by 5 with the increase of the percentage of quarry dust.

Quarry dust self compacting concrete as 2017525 the partial strength of concrete when stone powder is used to replace sand is obtained from 0 to 100 for every 10 M20 and M25 grade fine aggregate. The price of quarry dust in the process of aggregate extraction and processing is obtained.
January 23, 2018018332 this work focuses on how to effectively recycle waste plastics as alternative materials in concrete production. At 0.5, 10, 15 and 20, the fine aggregate quarry dust is partially replaced by granular plastic waste, and the resulting concrete is called p0.5, P10, p15 and P20, respectively.
Stone powder instead of sand has higher compressive strength than natural sand concrete. The purpose of this study is to determine the role of stone powder as fine aggregate in concrete.

Literature review on experimental study of dust effect in quarry the applicability of stone powder as sand replacement material shows that the mechanical properties and elastic modulus of stone powder are improved, and the compressive strength reaches the optimal value.
In the ordinary portland cement concrete, using different proportion of stone powder (such as 184.108.40.206) instead of artificial sand stone powder and laterite as fine aggregate in ordinary portland cement concrete instead of artificial sand stone powder and laterite.
Due to the reduction of natural sand sources and the reduction of concrete production cost, it is more and more necessary to determine the alternative material of sand as fine aggregate in concrete production, especially in concrete quarry dust. One of these materials is the by-product of the crushing process during quarrying activities.
