Durability Studies on the Recycled Aggregate Concrete in China

Since China hosted the Olympic Games in 2008, a mass of construction and demolition (C&D) wastes were produced with the rapid urbanization construction. Recycling the C&D waste into recycled aggregates (RA) is an effective method for reducing the amount of C&D wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in China …

THE IMPROVEMENT OF RECYCLED CONCRETE AGGREGATE A

2016-06-07 · mechanical properties for the recycled aggregate concrete. Meanwhile, the alkalinity of recycled aggregate concrete, chloride and sulphate contents of recycled aggregate have not been adversely affected. In the procedure shown in [12], the coarse recycled concrete aggregates were kept immersed in HCl with a molarity of 0.5 mole for 24 h.

Compressive and flexural behaviour of recycled aggregate concrete

The behaviour of hollow structural steel (HSS) stub columns and beams filled with normal concrete and recycled aggregate concrete (RAC) under instantaneous loading was investigated experimentally. A total of 40 specimens, including 30 stub columns and 10 beams, were tested. The main parameters varied in the tests were: (1) recycled coarse aggregate (RCA) replacement ratio, from 0 to 50%, (2 ...

Recycled Concrete

At Ernst, we see Recycled Concrete as an ideal product to be used as an alternative for regular gravel and is environmentally friendly. #2 Recycled Crushed is used as a sub base material for commercial and residential slabs and driveways, or as a backfill material.

USE OF WASTE PLASTIC AS FINE AGGREGATE SUBSTITUTE IN CONCRETE

hence in this study M20 cement concrete is considered in which the recycled plastic waste is used as the replacement of fine aggregate in the concrete. Concrete cube and beam were casted taking 10% to 25% of plastic as partial replacement of fine aggregate and tested for 28 days of compressive strength and flexural strength of concrete. 1.

EXPERIMENTAL INVESTIGATION ON GEOPOLYMER CONCRETE WITH

natural coarse aggregate with recycled coarse aggregates. Strength of the geopolymer concrete mix with M60 attains the same strength of lean concrete mix when compared to 3M, 4M and 5M (molar) so in this study the failure pattern of geopolymer concrete and “M60” concrete mix design are conducted.

Recycled Aggregates in Concrete • Aggregate Research International

2019-07-26 · Recycled Aggregates (www.cement.org) — Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or pavement sub-base layers.
