As concrete demand and conumption is increased rapidly demand of natural aggregate also rised. Similarly, the production of natural coarse aggregate is not sufficent ro satisfied these increased demand.Therefore, as a solution and to save enviroment the replacement of coarse aggregate in concrete is become essenetial.. Theare various alternative materials for coarse aggregate …

replacement of natural sand (Pofale et al 2013).The present study aimed to utilizing stone dust as fine aggregate in concrete in place of natural fine aggregate. For that an experimental programme was carried out to study the suitability and potential use of stone dust as partial replacement of fine aggregate in concrete.

Table 4 illustrates detailed concrete mix proportion containing GBS as replacement of natural fine aggregate (river sand) along with control mix made with natural aggregates. The mix design was carried out as per the standard procedures of IS 10262 (2009) .

The tile aggregate after crushing results in some material which is finer in size. This material is also included in concrete as replacement to fine aggregate since it is also a waste and similar to that of sand. The aggregate which passes through the 4.75mm sieve is used as a partial replacement to fine aggregate of 10% in

Concrete is then produced with replacement and was used as a partial replacement for fine aggregate. of 10%, 20%, 30%, 40% and 50% of plastic aggregate It was obtained from the Central Institute of Plastic replacement of plastic aggregate with the same mix Engineering and Technology (CIPET) Hajipur, Bihar, proportion.

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 ...

New driveway with custom stone entrance. The combination of elegant stone with a fresh new concrete drive create a long-lasting inviting entrance to this home. Attention to detail and quality instastallation are evident in the final product. more.

High-density polyethylene can be added to concrete and sand as a feasible replacement for course aggregate. Research has shown that plastic bags that are tightly packed and then heated, shrink to a size that can easily be used in concrete. But as the name implies, the material is too ductile at full strength to support structural loads at 2500psi.

– 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 …

Thirty kilograms of waste plastic of fabriform shapes was used as a partial replacement for sand by 0%, 10%, 15%, and 20% with 800 kg of concrete mixtures. All of the concrete mixtures were tested at room temperature. These tests include performing slump, fresh density, dry density, compressive strength, flexural strength, and toughness indices.

Recycled concrete aggregate (RCA) has been extensively researched as a way to improve the sustainability of concrete, eliminate construction waste, and address looming shortages of coarse aggregates. However, the goal of most research is to investigate high replacement levels and maximize the amount of RCA in the concrete.

Replacement of natural aggregate with waste tire rubber can have an undesirable influence on the mechanical properties of self-compacting concrete, i.e., compressive strength, flexural strength, splitting tensile strength, and modulus of elasticity, however.

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.

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 ...

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.

Also, a large amount of marble is accumulating in the environment due to demolition of old structures having marble.

Answer (1 of 6): It is advisable to not replace gravels with other consituents as possible as you can. Ofcourse coarse aggregates can be replaced with broken concrete debris however we are compromising the quality of resultant concrete upto some level that …

For concrete applications, glass aggregate is commonly in countertops but can be used for floors, walls, and other decorative designs. Another solution is to review epoxy terrazzo flooring and countertops, which go hand in hand with glass aggregates for any indoor environment to produce a durable, beautiful, and low maintenance surface.
