replacing natural silica sand with quarry aggregates
(PDF) Recent Trends in Replacement of Natural
Many researchers are finding different materials to replace sand and one of the major materials is quarry stone dust. Using different It is conventional that sand is being used as fine aggregate in concrete. The river deposits are the most common source of fine aggregate.

Performance evaluation of ternary blended cement concrete
Waste management is an environmental issue, and mining natural river sand (NRS) is more unethical and illegal. Thus, replacing fine aggregate with Granite Quarry Dust (GQD) foundry sand, etc., which could replace natural sand in concrete. They found that replacing sand by quarry dust could improve the compressive strength of concrete. However, the Sustainable development: Using stone dust to replace a

Analysis of strength properties of concrete containing sea sand
Sand is often utilized as a fine aggregate in concrete, contributing 22 to 62% of the total mass. The quantity and features of sand in concrete have an impact on its workability, mechanical characteristics, and durability. Effective replacements are needed as natural silica sand becomes scarcer. By incorporating these by-products into concrete, This research seeks to manufacture concrete by replacing fine aggregates in concrete with Fe-Al rich sand obtained from laterite scraps (mine waste) and fly ash-based cement. To reduce the colossal dumping of laterite scraps and curtail the utilisation of virgin aggregates, this study was done to utilise the laterite scraps effectively Strength and durability properties of quarry dust powder

Effect of quarry rock dust on the flexural strength
Concrete used was prepared by replacing 25% and 100% of sand by weight with quarry dust. Also, conventional sand concrete was prepared as reference concrete for comparison. 100 mm cube and 100 ×The materials which are used in this study include Cement (OPC 53 Grade), fine aggregates (Natural river sand), hard broken granite (Coarse aggregates), Quarry dust, Tandur stone slurry powder, Recycled aggregates (RA), Admixture conplast, and Water. These are the main materials that are employed in this proposed method.Experimental study of geopolymer concrete with recycled fine aggregates

An Experimental Study on Quarry Dust as Fine Aggregate in
The current research focuses on the experimental investigation on quarry dust in M50 grade mix concrete. The mechanical properties of concrete mixed with quarry dust as a fine aggregate were investigated in this paper. This research showed that natural river sand was substituted with quarry dust in a range of 0–100%.This study investigates the effects of partially replacing pit sand with quarry dust on the compressive strength of sandcrete blocks. Physical parameters of quarry dust and pit sand were determined in accordance with BS 1377–9 (1990), and sandcrete blocks were produced with 20%, 30%, 40%, 50%, 60%, 70%, and 80% quarry dust replacement The influence of partially replacing pit sand with quarry dust

Comparative study on strengthening of concrete using
2.4. Granite Aggregates. The main objective of the present study is just to compare the strength of the material to different grades of concrete by replacing basalt aggregates with granite chips. Initially, the granite sizes were available from 40 mm to 80 mm, so it was crushed manually to 20 mm-12.5 mm downsize.The ordinary portland cement was partially replaced with silica fume by 1.5%, 2.5 %, and 5% and natural sand was replaced with manufactured sand by four proportions (ie 10%, 30%, 50%, 70%).(PDF) The Effect of Replacement of Natural Sand by
