Reusable Concrete Debris as Aggregate Replacement on
2019-11-29 Some percentage of the concrete debris will be used as an aggregate replacement for concrete production. Six different concrete mixes containing 10, 20 and 30% of coarse and fine aggregate replacement were prepared accordingly. The concrete samples were tested for its strength at 3,7 and 28 days of curing age.

Recycling of construction debris as aggregate in the Mid
2004-10-1 Production of RPCC aggregate from construction debris that is processed on site using portable equipment moved to the construction site eliminates transportation costs for aggregate and provides an economic incentive for RPCC use. Processing costs, quality and performance issues, and lack of large quantities where needed limit RPCC use.

How to use aggregate production planning to succeed?
2021-10-26 Aggregate production planning (APP) is a method applied to manufactures to reduce costs and improve all kinds of productions related to manufacturing. This method helps to keep a balance between supply and demand in the market for a short or medium period of time. It takes around 3-18 months to conclude the aggregate plan.

Said Kenai, in Waste and Supplementary Cementitious Materials in Concrete, 2018. Abstract. Construction industry generates huge amounts of debris that needs to be recycled and reused as recycled aggregates (RAs) for partial or total substitution of natural aggregates. Recycling reduces waste and reduces energy consumption and hence contributes to a more sustainable
