Influence of recycled concrete aggregates on strength

Feb 01, 2009· 5.4. Experiment design. Four different kinds of coarse aggregate were used in the new concrete. These kinds included: (a) aggregates from natural origin, (b) recycled from unknown source (dump site), (c) obtained by crushing 30 MPa concrete (based on Mix 1), and (d) aggregate obtained by crushing 50 MPa concrete (based on Mix 2).

Influence of recycled concrete aggregates on strength

Recycling concrete wastes will lead to reduction in valuable landfill space and savings in natural resources. The objective of this study is to investigate the strength of concrete made with recycled concrete coarse aggregate. The variables that are considered in the study include the source of the recycled concrete and target concrete strength.

Effects of Recycled Aggregate on Concrete Mix and Exposure

Jun 25, 2019· The unit weight of the concrete ranged from 2365 to 2175 kg/m 3, depending on aggregate content (Figure 6).Increasing the recycled aggregate content reduces the unit weight and density of the concrete, resulting in lighter concrete (Figure 6).The unit weights of the 15%, 20%, and 25% mixes were reduced by 8%, 11%, and 11.5%, respectively, compared to plain concrete.

recycled in the manufacture of concrete and mortar. A larger part of these materials could be recycled into concrete to decrease the amounts of wastes which have to be disposed in landfill, and thus to preserve natural resources [1–6]. Old concrete is the most abundant material among various types of construction and demolition wastes.

Jun 01, 2018· 1. Introduction. Concrete is known as one of the most highly consumed construction materials. The primary ingredients of a concrete mixture are cement, aggregates (coarse and fine), water and admixtures (Mindess et al., 2003; National Ready Mixed Concrete Association (NRMCA), 2012).Among the aforementioned components, aggregate takes up about 70% to 80% of concrete’s
