Sahu et al 2003 reported significant increase in compressive strength modulus of rupture and split tensile strength when 40 of sand is replaced by quarry rock dust in concrete Rajamane et al

Performance of structural concrete with recycled plastic

Eleven concrete mixes tested with plastic as partial replacement for sand • Target compressive strength of 54 MPa to replicate structural concrete • Control of particle size distribution minimises change in compressive strength • PET fragments graded as sand can be used at a replacement

Replacement of Sand with Bauxite Mining Waste in Concrete

The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity as a sustainable construction material

Applications of Steel Slag Powder and Steel Slag Aggregate

The applications of steel slag powder and steel slag aggregate in ultrahigh performance concrete UHPC were investigated by determining the fluidity nonevaporable water content and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface The results show that the fluidity of the paste containing

Effect of quarry rock dust on the flexural strength of

Ahmed et al showed from an experimental study that the size of a concrete member has significant effect on the flexural strength and consequently proposed an equation incorporating the size effect f t 0827 h 01 f C 2 3 where fc is compressive strength in Nmm 2 and h depth of beam in mm to predict the flexural strength of concrete Previous studies have shown that replacing sand with quarry rock

Performance Evaluation for Flexural Strength of M30 Design

This research paper describes the study on high performance concrete while partially replace the fly ash and quarry dust as a cement and fine aggregate These are replaced at the percentages of 0
