fine aggregate using granite fines. K. Muthuwamy et al. [6] studied the use of crushed palm oil shell as a replacement material for fine aggregate in concrete. Crushed palm oil shell was introduced in the concrete specimens as partial sand replacement material ranging from 0%, 25%, 50%, 75% and . As the
Alternative sand can be classified as crushed rock sand (CRS), recycled fine aggregates (RFA), and industrial by-products. Alternative sand or manufactured sand is made from other than natural sources, by processing …
Nov 21, 2016 · Sand Alternatives for Aggregate. In a study released by the African Journal of Environmental Science and Technology, stone powder was pitted against sand as an alternative for fine aggregate. Sand is a naturally occurring material, while stone powder is a byproduct of crushing stone, usually for other projects.

Table – 1 Properties of the constituent materials Sl.No Parameter OPC used Brick Powder Fine Aggregate Coarse Aggregate 1 Normal Consistency 29% - - - 2 Fineness by Sieving (%) 90 micron mesh 80 - - -
The use of only Makurdi river sand as fine aggregate and gravel to produce grade C 35 concrete will cost N 16,559 a value lower than N 16,580 and N 16,622 obtained with the use of Makurdi river sand partially replaced with 10% …
Aggregate occupy about 60 – 70% volume of concrete. In this percentage 40 to 50 % proportion of aggregate is fine aggregate (sand). Fine aggregate selection plays vital role in concrete performance and its cost. Lately …
Fine aggregate was replaced with three percentages (10%, 20%, and 30%) of UFS by weight. Four concrete mixture proportions were made. First was the control mix (without UFS) and the other three mixtures contained UFS. Fine aggregate (regular sand) was replaced with UFS by weight. The proportions of fine aggregate replaced were 10%, 20% and 30%.
Natural sand is most commonly used fine aggregate in concrete. Owing to acute shortage in many areas, cost and environmental factors, an alternative for the same is pondered. The aim of this study was to investigate the possibility of using stone dust as partial replacement of fine aggregate. A referral M25
alternative fine aggregate are developed. In the present study, a comparison of the Compressive strengths of River Sand and M-sand is ... granite, feldspars, coal, soil, a wide . range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. Being such a simple technique of particle sizing, it is probably ...
The deficit of natural sand arise the need of alternative materials for replacement of natural sand. This experimental study explores in detail the crushed stone dust which is locally available industrial solid waste material in India as alternative material to natural sand that is being conventionally used as fine aggregate in cement concrete.
The use of stone dust in concrete provides environmental benefits by reducing the impacts produced by the extraction of natural sand. The use of this material can also offer economic advantages, since the product is less costly than natural sand. In this way, the present work evaluated the compressive strength of concretes made with stone dust in different …
Keywords: Concrete, Sea sand and Fine aggregate. 1. INTRODUCTION . Sand is a unique raw material for the construction industry at present, but contractors say that they have to spend more allocations for obtaining bulk loads of sand for their construction work. Quarry dust is one of alternative raw material for the construction industry,
Egg Shell As A Fine Aggregate In Concrete For Sustainable Construction S.A. Raji, A. T. ABSTRACT: This work has investigated the potential use of usedegg shell as a concrete material. The usedegg shells were used as fine concrete aggregate. In the laboratory test, conventional fine aggregate was replaced at replacement level.
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.
Granite dust is regarded as a valuable and easy-to-obtain alternative for customary, natural fine aggregate. However, granite dust can be employed in engineered cement composites (ECC). Nevertheless, multiple health and environmental hazards are attributed to it, due to the fact that it is a non-biodegradable material. The current study, however, has considered the …
stone dust as partial replacement of fine aggregate in concrete. To accomplish this specimen were cast for different replacement level at an interval of 10 percent to determine workability and compressive strength of concrete at different level of fine aggregate with stone dust. The percentage of stone dust was gradually increased in concrete ...
Stone dust (SD) is one such alternative material which can be successfully used in construction and used as partial replacement of natural sand. The influence of the SD on fresh and hardened properties of concrete are examined and presented in this paper. In this study, sand is replaced by stone dust in different percentages ranging from 0 to 60%.
Specifically, the study sought to look for possibility of substituting sand with crushed granite tile. Experimental design was implemented to determine the significant difference between cement mortar with crushed granite tiles as aggregate and that with sand as the fine aggregate, in terms of compressive strength.
Granite belongs to igneous rock family. Granite powder is used as a secondary material for fine aggregate. Granite powder is obtained from the granite cutting industry. The semi liquid substance released from the polishing process was termed as granite slurry, which will be stored in tanks and allowed for evaporation.
tiles and Granite powder were used as a replacement to the coarse aggregates and fine aggregate. The combination of waste crushed tiles were replaced coarse aggregates by 10%, 20%, 30% and 40% and Granite powder was replaced fine aggregate by 10%, 20%, 30% and 40% without changing the mix design. M25 grade of concrete was designed to prepare
stone dust as fine aggregate in concrete it is found that there is increase in compressive, flexural and tensile strength of concrete (Nagpal et al., 2013). It has been observed that 40% replacement of fine aggregate with stone dust is adaptable (Franklin et al., 2014). It was observed that the replacement of
concrete manufacturers to look for suitable alternative fine aggregate. One such alternative is "manufactured sand". Workability strength and durability of concrete with manufactured sand as replacement to natural sand in proportions of 0%, 5%, 10%, 15%, 20% and 25% is studied. The experiments were conducted on M20 concrete grade.
The alternative fine aggregates satisfies the requirements as alternatives to river sand. Crushed rock sand, industrial by-products and recycled fine aggregates are used as replacement of river sand. LCA shows reduction in terms of climate change and resource depletion over river sand. Standardization is needed for gainful utilization.
