Aggregate Replacement - an overview ScienceDirect

Moreover, the incorporation of 30% MIBA as aggregate replacement in concrete products decreased the amount of leached heavy metals. However, comparison to the TCLP limits for hazardous materials is not the most appropriate test, as the heavy metal concentrations released from the initial unbound MIBA were already within the limits outlined in GB-5085.3 (2007) .

Replacement Of Coarse Aggregate In Concrete - [Civil

2021-7-29  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.

2019-7-1  as well as on the health of the workers at the sight. To overcome such problems, aggregate can be replaced with coconut shell. In India 13 billion nuts of coconut produced every year which is huge source of coconut shell aggregate. Coconut shell concrete is a mixture of cement sand aggregate and crushed coconut shellaggregate. In this type of concrete the crushed stone aggregate is replaced partially or fully with crushed coconut shell, to utilize the environmental sources and to protect the environment. Thus the main aim is to utilize the coconut shell and to achieve the strength with different percentage of coconut shell aggregate

Replacement of Coarse Aggregate by Demolished Brick

2017-8-12  In this present work the study on replacement of coarse aggregate by demolished brick aggregate. Coarse aggregate can be defined as inert granular materials such as gravel, crushed stone and sand. Coarse aggregate is one of the essential ingredients apart of water and cement in concrete production. The only variable considered in this study was the volumetric replacement (0%, 25%, 50%, 75%, and 100%) of stone aggregate by brick aggregate. The use of brick aggregate as a replacement of stone aggregate resulted reductions in unit weight, compressive strength of concrete. Different relations for determination of compressive strength, splitting tensile strength of mix-aggregate concrete have been tentatively proposed. The 25% replacement
