Partial Replacement of Coarse Aggregate with Broken ...

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. Control mixing ratio of 1:2:4 batched by weight with water – cement ratio of 0.55 was used. The percentage replacement varied from 0% to 40% at intervals of 5%.

What happened when we not used 20 mm size aggregate

Answer (1 of 2): Potentially, the drying shrinkage will be higher, as will be the heat evolved. Both due to a higher cement content. I am assuming that you want to replace the 20mm with 14 or 10mm coarse aggregate, and not just omitting the coarse aggregate entirely. Omitting any coarse aggrega...

Replacement Of Coarse Aggregate In Concrete - Civil

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 ...

Cement Replacement Material - an overview - ScienceDirect

Concrete is an artificial stone manufactured by mixing together coarse and fine aggregates, cement, water and often other components such as cement replacement materials, e.g., pulverised fuel ash, and chemical admixtures, e.g., superplasticisers. The grading of an aggregate defines the proportions of particles of different size in the aggregate.
