The physical and mechanical properties of materials used in Plastic Paver block were
· the state, alternative materials for sand have become inevitable. Smart sand or manufactured sand are proved alternatives for the natural sand in cement concrete production. Quarry Dust which is the waste tailing and residue generated from the crushing of rock stone into
· natural river sand has become scarce and very costly. Hence we are forced to think of alternative materials. The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures.

· A related study conducted by Verma et al. (2020), a form of quarry dust referred to as stone dust was utilized as a partial natural sand replacement. The stone dust was incorporated at 10% to 40% by mass of fine aggregate at a stepped increment of 10% in a binary and ternary binder system containing up to 15% of silica fume.
· For the production of sand-cement bricks, three (3) different composition of cement to sand ratio were prepared (1:2.5, 1:3.0 and 1:3.5), with constant water/cement ratio of 0.5 for all composition. The amount of QD incorporated in the sand-cement mixtures known as Sand-Quarry Dust Cement (SQDC)
the introduction of quarry dust as a substitute of sand in block production. This paper focuses on a comparative analysis of the quality of sandcrete blocks and quarry dust cement blocks.
· Quarry dust has rough, sharp and angularparticles, and as such causes a gain in strength due to better interlocking. Quarry dust has been identified as possible replacement for sharp Propertysand Testin concrete works. Jayawardena dustand Dissanayake [5, 6] in their paper "Use ofquarry dust instead of river sand for
The use of laterite, quarry dust and recycle aggregates etc as replacement for sand in sandcrete block production is common trend in developing countries like Nigeria. Most resources and research efforts are committed towards conducting trial test with a view to coming up with mix production that will yield the desired property. This work presents a mathematical model for …

In most villages, mud and clay materials are still being used for wall making with their acceptability as last alternative for the poor but, with some level of quality ... sandcrete block sample was sourced as river sharp sand while the cement …
quarry dust as alternate to sand in concrete We provide crushing & grinding products and solutions . CRM Mining Crusher is a Porland company with facilities in Europe and Africa that manufactures and installs crushing, grinding, and screening equipment and spare parts for mining, quarrying and demolition operations.
· Concrete is very variable material, having a wide range of strengths and stress-strain curve. Concrete composite material whose basic properties are related to the characteristic of constituent element, especially the aggregate. This research aimed to investigate the effect of replacing sharp sand with stone dust as an alternative to only river sand.
· Owolaja Glory. This study investigated the prospect of utilising red earth, quarry dust and laterite as alternative materials to river sand in the production of …
gravity of both the materials i.e. sand and quarry dust were found to be almost same. It was suggested that the ideal percentage of replacement of sand with quarry dust can be between 55-75%. It was also suggested that 100% sand can also be replaced with quarry dust in presence and usage of fly ash. III. H. S.

· river sand for concrete and block work, alternative materials like laterite, quarry dust and recycled aggregate etc. are being sourced for as partial or full replacement for river sand. Full replacement of river sand with a blend of quarry dust and laterite in the production of blocks is a growing phenomenon in most cities across Nigeria.
· A possible alternative to natural sand in production of concrete is quarry dust, a by-product of rock quarrying. Quarry dust has particle sizes in the range of 0.05-5 mm and
· The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in …
· C. Quarry dust The quarry dust is the byproduct of granite stones which can produced when stones broken down into the coarse aggregates of different sizes.
