Sand Substitute Developed By Indian Scientists For Eco Friendly Construction The team has also developed 3D printable materials made of excavated soil stabilised with a combination of binders like
This usually includes greater use of material resources like extra insulation thermal mass etc Akadiri and Olomolaiye 2012;Jiang et al 2017
Sand is a limited material and the second important natural resource in this world It also plays an important role in many civil engineering applications including concrete/asphalt aggregate road base stabilization construction fill and other mortars
Crushed Sand is used instead of natural sand since the desire for sand has surged due to the fast increasing construction projects resulting in a lack of appropriate river sand throughout most regions of the world Thus the use of synthetic sand as an alternative construction material can help to keep construction costs under control
This sand is manufactured by crushing granite or basalt rock Since it is manufactured it can be created based on IS codes and can be used instead of river sand for construction purposes Size of Sand Sand can also be differentiated by size of sand Smaller sand is considered fine while larger particles are considered coarse Fine Sand Used

When it comes to construction the quality of materials used plays a pivotal role in determining a structure s strength durability and longevity Among these materials sand is a crucial component that directly affects the performance of concrete and mortar The 10 methods that are used for checking the quality of sand used in construction
Concrete is utilised as the most popular construction material which produces the most carbon emissions during the fabrication and manufacturing process Therefore the replacement of SCGs instead of sand in concrete production would result in A$/m 3 cost savings Worth to mention that considering the landfilling cost and levy of
The United Nations has declared a global sand crisis called for reduced sand consumption and proposed solutions to address the crisis including adopting sustainable substitutes for sand The construction industry is a major consumer of sand yet a recent study found a very low level of awareness by stakeholders of the crisis The purpose of this study is
The literature revealed that some classes of waste can be converted into useful products and these include kitchen and organic waste metal glass plastic and paper Ojewumi et al 2019a
concrete Therefore construction industries should find out alternative materials to replace the demand of sand in construction industry for sustainable development reason The use of waste materials as by product from industries such as stone dust to replace natural sand in
The compatibility of stone dust and sand with other construction materials is a crucial factor Exploring how these materials interact with concrete steel and other elements ensures seamless integration in construction projects Ease of Use in Construction The ease of handling and applying stone dust or sand on construction sites varies
Two rectangular reinforced concrete beams were tested to pilot further investigations one with normal concrete mix of 1 2 4 and the other with the concrete 1 1 1 2 3 with soft laterite as fine aggregate instead of sand The ultimate moments of resistance of the two beams are almost the same although the beam of normal concrete offers greater flexural
The results show that the maximum compressive strength of concrete is 10% GT instead of sand and the strength improved by % tailings can improve the performance of construction materials
There was no significant reduction in the compressive strength up to 40% of dosages of oyster shell instead of sand The experimental results demonstrate that oyster shells can be resources of pure calcareous materials and effective in replacement of sand indicating promising reusable construction materials
Tailings can be used as embankment materials instead of sand However they contain large amounts of heavy metal pollutants which can lead to groundwater pollution In this study lead zinc Pb Zn tailings with five particle sizes and Sporosarcina pasteurii were used as test materials Combined with the unconfined compressive strength UCS and leaching of
Hollow concrete blocks HCBs are substitutes for conventional bricks and stones in building construction Experimental testing has been performed on the feasibility of producing HCBs from sawdust
Material The ordinary Portland cement of 43 grade which meets the Indian Standards specification was used in the concrete mixtures [] Table 1 shows the physical parameters of cement In this study fine sand and gravel of 10 and 20 mm size were employed and physical aggregate properties are listed in Table 2 [] Throughout the trial only tap water
The literature review reveals that there is a lack of studies that evaluate plastic sand construction materials from an economic perspective Such studies are essential if the industry is to
This advancement on the 3D printed materials could serve as a sustainable substitute capable of replacing up to 75% of natural sand in cement based construction materials
