What material can I use as a replacement of coarse

Ofcourse coarse aggregates can be replaced with broken concrete debris however we are compromising the quality of resultant concrete upto some level that doesnt make any harm to building as a whole. Gravels are the best suited for coarse aggregate for various physical and chemical reasons.

Feb 03, 2021· 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.

What Materials can be used as Fine Aggregate Replacement

– size and shape should accommodate for rheology and hardened state properties of concrete Should cater to early age properties of concrete by providing adequate resistance against shrinkage. Practically, anything from furnace bottom ash to lightweight pumice can be used as aggregate it depends on what the specifications for concrete are.

Concrete: Cement Substitutes GGBS, PFA and more

Very occasionally, it can be found up to a ratio of 90% GGBS and 10% Pc. Concrete made with GGBS cement sets more slowly than concrete made with ordinary Portland cement, depending on the amount of GGBS in the cement mix, but also continues to gain strength over a longer period leading to improved overall durability and life expectancy. Silica fume

Aggregates Portland Cement Association

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories--fine and coarse.
