Recycled aggregate concrete: Particle Packing Method

In this context, the recycled aggregate (RA) is an effective alternative to natural aggregate. But, the use of RA has not gained popularity yet, because of the inferior quality of RA and yielded recycled aggregate concrete (RAC) using RA. The proposed Particle Packing Method (PPM) of design mix is executed along with the established Two Stage

Recycled Aggregates in Concrete • Aggregate Research

These crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregate. Crushed concrete aggregate eliminates the need for

Admixtures From Recycled Aggregates| Concrete

Nor did the recycled aggregate from the air-entrained concrete have any significant effect on the air content of the new concrete. The air containing calcium chloride did raise the chloride content of the new concrete, but not enough to account for all the original chloride.

Mix design of recycled aggregate concrete using

By using packing density mix design method, recycled aggregated concrete strengths fluctuation can be resolved, and the concretes can have similar strengths consistency, regardless the recycled concrete aggregate replacement ratios. This method minimise the influence of recycled concrete aggregates obtain from various sources with variable quality.

15/11/2017· Due to this the recycled aggregates of size 10mm to 20mm are obtained. These recycled aggregates are wet they are dried by keeping in oven for 24 days. The different tests are carried out on finally obtained recycled aggregates and Mix design of concrete of grade M20 by using IS 1260:2009 and 456:2000. 8.

Recycling of Concrete (Recycling Coarse Aggregate)

Keywords—Recycled Coarse Aggregate (RCA), Concrete Mix Design(CMD), Natural Aggregate(NA) I. INTRODUCTION As we know the term ‘concrete” is a mixture of cement + sand + coarse aggregate with water. Concrete is widely used in both substructure and super structure as main constructional material. It is most important substance of a structure. There is 3-R system in each industry which is

PERFORMANCE OF RECYCLED AGGREGATE CONCRETE

performance of a concrete. In this paper, the effects of various percentages (0%, 25%, 50%, 75%, 100%) of Recycled Aggregate (RA) on compressive strength of Recycled Aggregate Concrete (RAC) were investigated. RA is used to replace natural aggregate (NA) as coarse aggregate in concrete mixes. This research also covered RAC mixtures at

Recycled Aggregate Concrete SlideShare

15/11/2014· It is called recycled aggregate which can be produced by concrete crusher. The aggregates are categorized by size as coarse and fine aggregate. The characteristic of recycled aggregates could be different by its parent concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete
