Replacement Of Aggregate In Concrete

Aggregate Replacement - an overview | ScienceDirect Topics

Leaching tests on the granular form of concrete made with MIBA as a complete aggregate replacement were undertaken in accordance with EN-12457-2 (2002) (single-stage batch leaching procedure), the results of which are shown in Figure 8.7 (Ginés et al., 2009).It was found that concrete using MIBA as a substitute for natural aggregate, though evidently showing increased element release, can be ...

Replacement Of Coarse Aggregate In Concrete - [Civil Planets]

Using the E-waste 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 of the concrete.

5 Eco-Friendly Alternative Aggregates for Concrete!

21/11/2020· Aggregate Replacement for Concrete. Concrete replacement materials can be of many types. You can replace the cement in concrete with recyclable materials to reduce energy consumption. The list of waste materials used in concrete can consist of wood ash, fly ash, blast furnace slag, or silica fume. Such type of ecological form of concrete is known as Green Concrete. Another effective …

Partial Replacement of Fine Aggregate in Concrete by Tyre ...

Keywords—Concrete; replacement of fine aggregate ;scrap rubber; I. INTRODUCTION. Utilization of scrap tyres should minimize environmental impact and maximize conservation of natural resources. One possible solution for this problem is to incorporate rubber particles into cement-based materials. Scrap tyres can be shredded into raw materials for use in hundreds of crumb rubber products. The ...

Use of Waste Plastic as Fine Aggregate Substitute in Concrete

used as the replacement of fine aggregate in the concrete. Concrete cube and beam were casted taking 10% to 25% of plastic as partial replacement of fine aggregate and tested for 28 days of compressive strength and flexural strength of concrete. 1. INTRODUCTION . The research in to new and innovative waste materials being under taken world-wide and innovative ideas that are expressed are ...

Replacement of coarse aggregate by Polyethylene ...

the density of concrete. Mixture proportions of concrete were planned so that the water/cement ratios were 45%, 49%, and 53%, and the replacement ratios of WPLA were 0%, 25%, 50%, and 75% by volume of fine aggregate. Density of concrete mixtures decreased with the increase in WPLA content. In their study the influence of polyethylene terephthalate

What are the Materials for Replacement of Sand in Concrete ...

A concrete mix necessarily contents cement, water, fine aggregate and coarse aggregate. 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.
