However, using a recycled aggregate of more than 65% can impact the mix's durability significantly, reducing its physical properties tenfold. The optimum amount blended in with the concrete should be 35%. Some experiments have shown that the recycled aggregate is durable, no doubt, but not as sturdy as natural coarse aggregate.
of fine aggregate with polypropylene pellets (PP) is the only local study that maximized pellet materials in the Philippines using nominal size CHB 4" x 8" x 16" and following the standards for CHB in the country (Lasco et al., 2017). However, studies that maximize the use of other types of plastic materials like
Limestone powder for building material. It is used in the production of cement by heating powdered limestone with clay. Cement is an ingredient in mortar and concrete. Mortar – used to join bricks together – is made by mixing cement with sand and water. Concrete is made by mixing cement with sand, water, and aggregate/crushed rocks.
