Waste as meaningful substitute for natural sand
The new application of WCS as a partial substitute for sand also triggered the change of the Singapore’s Aggregates standards which allows both natural and nonnatural aggregates including recycled aggregates in concrete, thereby opening the door to the more use of recycled/waste materials in concrete The American Concrete Institute Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensusbased standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design Properties of Concrete Using Copper Slag as a Substitute Crushed Sand a Substitute for River Sand as a Fine Aggregate in Concrete Saurabh A Dhon1 Dhulappa B Borkar2 1,2Department of Civil Engineering 1,2Fabtech College of Engineering Research, Sangola, Solapur, Maharashtra, India Abstract— Concrete is a dominant part of construction industry In India, ordinary concrete contains natural sandCrushed Sand a Substitute for River Sand as a Fine
A Review on Partial Substitution of Copper Slag with
copper slag as a partial substitute of Sand (up to 40%) in concrete but in terms of stability the concrete found to be low resistant to acid attack and better resistance against sulfate attack[7] Pranshu Saxena et al [2015] they studied about scope of replacement of fine aggregate from copper slag in concrete Copper slag is a best substitute for river sand in cement mortar and concrete, to overcome the environmental problems created due to over mining In this investigation, in a cement mortar and concrete replacing natural sand by granulated blast furnace slag in a range of 20%, 40%, 60%,80% and 100% The workability and strength of cement mortar and concrete with EFFECT OF GRANULATED BLAST FURNACE SLAG AS Research on natural crushed rock sand, copper slag, waste foundry sand, coal ash, recycle sand etc has shown that these can also be used in concrete as fine aggregate [7, 8], either in full or as fractional replacement of natural sand [810]Alternative Sand: An Inevitable Resource to River Sand
USE OF WASTE PLASTIC AS FINE AGGREGATE
hence in this study M20 cement concrete is considered in which the recycled plastic waste is used as the replacement of fine aggregate in the concrete Concrete cube and beam were casted taking 10% to 25% of plastic as partial replacement of fine aggregate and tested for 28 days of compressive strength and flexural strength of concrete 1 25 billion tons of concrete are produced globally each year, or over 38 tons per person per year (Marinković) With so much concrete being produced annually and the incredible amount of trash that is cluttering the environment, using that trash and debris as aggregate in concrete sounds like it is at least worth trying We couldRecyclable Waste Material as Substitute Aggregate in The results proved the arrest of the propagation of micro cracks by introducing waste plastic of fabriform shapes to concrete mixtures This study insures that reusing waste plastic as a sandsubstitution aggregate in concrete gives a good approach to reduce the cost of materials and solve some of the solid waste problems posed by plasticsUse of waste plastic in concrete mixture as aggregate
