New type of crushed sand to replace natural sand in
New type of crushed sand to replace natural sand in concrete production. The availability of natural sand for concrete production is facing challenges, while the so-called waste stockpiles at aggregate The augmented interaction among constituents is attributed to the enhanced shape and texture of crushed sand particles, resulting in a bolstered concrete Feasibility study on impact of replacement of river sand with

Investigation into the Effect of Replacing Natural Sand by
In the context of sustainable development and environmental protection, the current study aims to give scientific evidence of the feasibility of replacing natural siliceous sand with crushed limestone sand in concrete. It assesses the effect of this replacement by comparing concretes without natural sand to a reference mix noted upon the replacement of fine aggregate with 30% of crushed rock sand [25]. The low workability with crushed rock sand can be rectified by the usage of high range water reducers [26]. Another study [27] reported that both the mechanical and durability properties improved by 14% compared to the properties of the normal concrete.IOP Conference Series: Materials Science and Engineering

Performance of recycled waste glass sand as partial replacement of sand
This research studied the use of mixed coloured soda-lime glass supplied by Cairns Regional Council, Australia as sand replacement in concrete. In this research, concrete with a target characteristic strength of 32 MPa was produced by replacing natural river sand with 20%, 40%, and 60% of crushed recycled glass sand (RGS) to Literature reveals an optimum replacement level of natural sand by SD as 40, 50 and 60% depending upon the characteristics of SD. The optimum range may vary from 40 to 60%. Depending upon fineness of SD, the optimum replacement level was observed 40% as evident from the test results on CS, TS and durability properties of Utilization of Stone Dust as an Effective Alternative for Sand

Effect of total substitution of crushed limestone sand on concrete
Abstract This article examines the effect of total substitution of siliceous sand by crushed limestone sand in mortar and concrete with regard to durability. Crushed limestone sand is a by-product of quarries containing a significant amount of fines characterised by a ‘spread out’ grain size distribution having a maximum diameter of This study aims primarily to examine sand replacement to optimize the benefit of industrial by-products and other waste materials. Day by day, demand for sand is July 2015 1 gave excellent results in terms of compressive strength. ISSN 2250-3153.

study was to evaluate the effect of percentage replacement of natural sand by manufactured sand at 0%, 10%, 20%, 40%, 60%, and 100%. Statement of the problem Natural sand deposits are being depleted and causing serious threats to the environment as well as society. Increasing extraction of natural sand from riverEcological resources are constantly consumed to produce concrete, resulting in environmental damage. This is also one of the issues for environmental sustainability. This study discovers a replacement material of river sand and stone aggregates produced from sustainable utilization of renewables to save the environment.

Comparative Study on Natural Sand and Crushed Stone Sand
crushed stone sand Keywords— Crushed stone sand, natural sand, physical properties. I. INTRODUCTION Crushed stone sand is a common by-product of mining and quarrying. Rather than being discarded it as a waste material it can be utilized in various construction processes of the pavements. The crusher dust is also known as the M-sand.replacement performs similar to sand if not better. Steel slag is one waste material that can exhibit granular nature similar to sand on crushing, so much so that there have been investigations involving steel slag as replacement for sand [12]. Another waste material that can be used as potential replacement for sand is crushed glass.VALORIZATION OF CRUSHED GLASS AS A POTENTIAL REPLACEMENT FOR SAND

Euibae Lee, Sangjun Park, Yongjic Kim (2016) In this study, experimental results are presented to evaluate the drying properties of concrete shrinkage using dune sand (DS) and crushed sand (CS) as fine aggregate (FA). Concrete mixesHowever, at 100% replacement of crushed glass by weight of sand in concrete, the compressive strength test result both at 7th and 28th days showed a decrement. It is conjectured that at a point, after it attained its optimum compressive strength value (80% crushed glass replacement), the strength has began to fall down.Structural Performance and Characteristics of Concrete with Crushed
