paper deals with replacement of sand used in concrete as fine aggregates by the waste generated by the Mucking particles. This study has made an attempt to partially replace mucking dust in place of sand in M30 grade concrete. On experimentation, it was found that the partial replacement of sand with 40% of mucking

concrete properties for hardened and fresh concrete by replacing the normal aggregate (sand) with the fine crushed concrete waste. Construction Waste.

when comparing traditional aggregate concrete with mixes containing recycled rubber. These values include mix prepared using partial replacement of natural aggregates by rubber particles treated with sodium hydroxide solution. Concrete containing rubber aggregate has the energy absorbing capacity in

use of recycled polypropylene as partial replacement of fine aggregate in concrete. Tests such as specific gravity and sieve analysis were carried out on the recycled polypropylene waste. Concrete slabs (600mm x 400mm x 50mm) and cubes (150mm x 150mm x 150mm) were made from the mixture of

ABSTARACT:- Concrete is made up of cement, fine aggregates, coarse aggregate, water and admixtures if necessary. Laboratory experiments were conducted on strength characteristics of concrete made with utilizing broken waste glass as 5%, 10%, 15% and 20% by weight of coarse aggregates for M-20 mix. These mixes were prepared following a specific W/C

Coarse aggregate = 22.2 kg Fine Aggregate = 11.16 kg. By replacing 15% of cement by ceramic waste 15% of 8.5 = 1.275 kg. Therefore, Final Mix for 15% replacement: Cement = 8.5 1.275= 7.225 kg. Water = 3.83 litre. Coarse Aggregate = 22.2 kg Fine Aggregate = 11.16 kg Ceramic waste = 1.275 kg. 7 days. Sample 1. Compressive load = 590 KN Compressive Strength =5901000

Recycled waste glasses were used as sand replacement in concrete at 0, 25, 50, 75, and 100% replacement ratios. Diverse concrete properties were tested in fresh and hardened states with three

It was discovered that plastic usage as a coarse or fine aggregate replacement decreases the concrete compressive strength [24,25,36,47,48,51,52,55,56,[61][62] [63] Fig. 5 shows the strength of

usage for concrete mix as partial replacement, this study conducted an experimental investigation using crumb rubber aggregate as partial replacement for fine aggregate in the production of load bearing concrete hollow block (CHB). 2. Methodology This study

flexural strength of concrete can be obtained in recycled aggregate concretes containing upto 50% RFA as partial replacement of NFA. However, in the case of recycled aggregate concretes containing 30% and 40% fly ash the compressive strength is increase at 56 days and both compressive strengthand tensile strengths are decreased at early ages.

Jul 25, 2017 · Natural fine aggregates (river sand) are replaced by the recycled fine aggregates by the different percentage levels for the production of fresh concrete. A comparative interpretation on the strength characteristics of the concrete produced with Ordinary Portland Cement and Portland Pozzolana Cement is also presented and discussed in this paper.

From the experimental study, it was observed that compressive strength & tensile strength of concrete with recycled aggregates increased up to 20% replacement of natural aggregates with recycled aggregates whereas the flexural strength of recycled concrete was found to decrease with increase in percentage of RCA & RFA.
