So as to abstain from utilizing common stream sand. An elective material is proposed to the quality of the solid by supplanting of fine total. Incompletely by squander material like copper slag which is an ecological waste. To make us of these
Nov 04, 2013#0183;#32; The purpose of this paper is to examine the use of a waste marine sea shell product incorporated into a concrete mix as an aggregate replacement. Utilising shells reduces the storage of shell waste, also reducing the need for quarried aggregate and has potential benefits of adding a different material to a design mix concrete mix design for improved performance., The test
This paper presents a review of the literature published so far on the use of fine aggregates from construction demolition waste used as a partial or total replacement of fine natural aggregates in concrete production. The review presents the initial works on this subject
beads based concrete is obtained by partially replacing coarse aggregate with different dosages of polystyrene beads volumetrically. The quantities of materials for various mixes are obtained by partial replacement (by volume) of coarse aggregates by EPS beads. Cubes of 150mm size for compressive strength evaluation and
The environmental and economic concern is that the biggest challenge the concrete trade is facing, the problems of environmental and economic concern are selfaddressed by the utilization of waste glass as partial replacement of fine aggregates in concrete. Fine aggregates will be replaced by waste glass powder as 5%, 10%, 15%, 20% and 40% weight for M20 mix.
This paper presents the results of an experimental investigation on the properties of concrete using copper slag as partial replacement of fine aggregate. For this research work, M20 grade concrete was used and tests were conducted. Various concrete mixtures were prepared with different proportions of copper slag as fine aggregates replacement.
Using the Ewaste as a partial replacement of coarse aggregate in concrete is the best solution. We can not fully replace material in concrete because it impacts the workability of concrete . The electronic waste is crushed as required particle size and can be mixed with other aggregates in concrete which will not affect the quality amp; durability of the concrete.
The suitability of quarry dust as alternative material for the river sand in concrete manufacturing is studied. M25 grade concrete was prepared with 0%, 20%, 40%, 60%, 80% partial replacement of
The workability for 540% replacement of coarse aggregates with plastic synthetic aggregate ranges from 1261mm as against 8mm for the control test (0% replacement). View fulltext Article
Both the fine and coarse aggregate were replaced by 10%, 20%, 30%, of CS and RCA by weight from RESEARCH 17(47), 2020 ARTICLE RESEARCH the control mixture (concrete mix
partial replacement of cement and fine aggregate for rigid pavement in road construction. In developed countries use of mineral admixtures such as fly ash, silica fume, plastic waste and rise husk ash etc is already adopting to prepare concrete. This includes commercial application on large scale either for addition or for replacement of cement.
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of Portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates which hardens over time. Mostly used concrete is the limebased concrete which is the Portland cement concrete.
Oct 27, 2020#0183;#32;The fibre obtained from basalt rocks known as basalt fibre is used in concrete in recent years and have attracted a lot of attention. In this paper, glass powder is used as a replacement for fine aggregate while basalt fibre is added to improve the mechanical properties of concrete.
An Experimental Investigation on M30 Concrete with Partial Replacement of . Fine Aggregate by GBS . B. Naga Niranjan Kumar, J. Saran Kumar, Rajarao . Department of Civil Engineering, Reddy Institute of Technology, Kurnnol, Andhra Pradesh, India . ABSTRACT . Now a days construction material is more important in utilization
Mar 04, 2020#0183;#32;One of the solutions suggested was the use of tyre rubber as partial replacement of fine aggregate in cementbased materials. An experimental program was carried out to investigate the compressive strength of concrete with shredded tyres as a fine aggregate in concrete .A number of cubes, prisms, cylinders were casted of M25 grade for this study.
aggregate will be studied for compressive strength, tensile strength and flexural strength. the percentage replacement will be 0%, 10%, 20% and 30% with natural coarse aggregates and replacement of 10% various size of coconut shell in concrete. the
Dec 01, 2016#0183;#32;It can be observed that sugarcane, giant reed, and rice husk are produced worldwide and they have a similar type of processing, those are burnt to convert into sugarcane bagasse ash, giant reed ash and rice husk ash. These are used as partial replacement of fine aggregate which provide additional pozzolanic property in concrete.
The results presented an enhancement in the mechanical properties compared with conventional concrete. Awoyera et al 17 used ceramic as a partial replacement for fine and coarse aggregate. The replacement percentages used were 25%, 50%, 75%, and for each mix as fine and coarse aggregate replacement.

with constant w/c ratio were prepared and tested. The reference concrete mix was made withconventional coarse and fine aggregates (crushed stone and natural sand). Five mixes were prepared incorporatingcoarse ceramic aggregate as partial substitute of coarse aggregate with replacement levels of 10%, 20%, 30%, 40%, and 50%.
partially replacing fine aggregates with quarry dust in concrete. The main aim focus of this paper was to quarry dust partial replaces natural sand in concrete for studying the hardened strength properties of concrete. Natural sand was replaced with Quarry dust by three proportions ( 10%,20%, and 30%). The study was carried out on M20
waste rubber tires to partially replace fine aggregates in the production of concrete. hollow blocks (CHB). Three mixtures in the proportions of 20%, 40% and 60%. crumb rubber replacement were evaluated for compressive strength of CHB at curing. age of 7 days, 14 days and 28 days respectively.
