Abstract— The study reports on experimental investigation on the suitability of the use of broken tiles as partial replacement for crushed granite in concrete production.
replacement of coarse aggregate with polystyrene (as a partial replacement of aggregate), higher the polystyrene replacement, higher was the workability. Bleeding was observed with the increase in water/cement ratio. Compactions of the specimen were done with vibrating machine, high
Jul 10, 2018· Concrete is a composite element consisting of aggregates enclosed in a matrix of cement paste including possible pozzolanic, has two major componentscement paste and aggregates. As a construction material, concrete can be in almost any shape desired, and once hardened, can become a structural (load bearing) element.
coconut shell concrete with the replacement of 16%, % and 20% by coarse aggregate By testing the concrete cubes, at th28 day 16% replacement of coarse aggregate by coconut shell shows that the strength of the coconut shell concrete was decreased by .
According to R. Nagalakshmi, M25 grade of concrete with cement replaced by fly ash and coarse aggregate by coconut shell and find its compressive, tensile strength. 5. According to Sabarudin Bin Mohd, he replaced coconut shell and palm kernel shell in place of coarse aggregate in concrete in 0,25,50,75 and 100 % replacement.
Coarse Aggregates Coarse aggregates are particles greater than, but generally range between to in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or '''', aggregates are either Land or MarineWon. Gravel is a coarse marinewon aggregate; land
the concrete industry to use waste glass as partial replacement of coarse or fine aggregates and cement. In this study, finely powdered waste glasses are used as a partial replacement of cement in concrete and compared it with conventional concrete. This work examines the possibility of using Glass powder as a partial replacement of cement for ...
Oct 01, 2019· As seen in Fig. 6, in concrete mixes with CCW, regardless of the coarse aggregate''s maximum size and the number of freezethaw cycles, the concrete mix with replacement of NCA displayed the most positive effect of using CCW on the resistance to freezethaw cycles. The concrete mix with CCW with maximum sizes of 25 mm, 20 mm and ...
the seashell as a coarse aggregate in concrete along with partial replacement of cement by flyash of 25%. Further it was planned to extend the studies into workability characteristics while using seashell as partial replacement. This can be effectively used for the improved concrete construction with local materials.
Replacement of Coarse Aggregates with Jhamma Bricks for Preparation of Concrete Sankarsan Mohanty. Concrete is considered the world''s most used construction material. Typical concrete mixtures are comprised of water, sand, cement and an aggregate of rock. This civil project focuses on the coarse aggregate in concrete.
This study investigates the suitability of crushed coconut shell (CCS) and polyethylene terephthalate (PET) as partial replacement of coarse aggregate in concrete. The PET was crushed mechanically to sizes between 010mm while the CCS was crushed manually to sizes between
Jan 01, 2016· The feasibility of utilizing Ewaste plastic particles as partial replacement of coarse aggregate has been presented. In the present study, compressive strength was investigated for Optimum Cement Content and 10% Eplastic content in mix yielded stability and very good in compressive strength of 53 grade cement. ... An experimental study is ...

Fig 6: Partial replacement of coarse aggregates with rice husks. At 5% replacement ratio of coarse aggregates, the concrete had the highest compressive strength of As the rate of replacement increased, ie, 10%, 15%, 25%, 50%, 75%, and the compressive strength was,,,, and
in partial replacement of coarse aggregate in m20 concrete". IJRET: International Journal of Research in Engineering and Technology. Concrete is a pourable mix of cement, water, sand, and gravel that hardens into a super strong building material. In the recent decade''s demolition of .
used as partial replacement to coarse aggregates in Vijayaraghavan and A. S. Waya (2013) obtained the results of experimental investigations of partial and full replacement of natural sand. The main aim of their study was to compare the compressive strength and
Electronic waste or ewaste describes discarded electrical or electronic devices. Used electronics which are destined for reuse, resale, salvage, recycling or disposal are also considered as ewaste. Informal processing of electronic waste in
aggregate is basically sands won from the land or the marine environment. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a sieve. As with coarse aggregates, these can be from Primary, Secondary or Recycled sources. Chemical Composition Limits (%) 1 CaO 61 67 2 SiO 2 1923 3 Al 2
possible in construction by using steel slag as a partial replacement material for fine aggregates in concrete. P. Vignesh Kumar, (2014), in this study of partial replacement of coarse aggregate with iron slag in the cement concrete have greater strength than the conventional concrete. As the selfweight of this concrete is higher.
B. Coarse Aggregate: as coarse aggregate in concrete consist 35 to 70% of volume of the aggregate with specific gravity more than and absorption less than %.the physical properties of coarse aggregate is shown in table 2.
Coarse aggregate, plastic aggregate, partial replacement, volumetric substitution, grade substitution. I. INTRODUCTION: Concrete is the most widely used man made construction material in the world and its second only to water as the most utilized substance in the planet.
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 durability ...
