DURABILITY OF GREEN CONCRETE WITH TERNARY CEMENTITIOUS SYSTEM

Durability of Green Concrete with Ternary Cementitious System Containing . . . . 903 Journal of Engineering Science and Technology June 2016, Vol. 11(6) gravity and water absorption rate of the RCA were 2510 kg/m3 and 4.7%,

Use of Recycled Aggregate and Fly Ash in Concrete Pavement

In general, the RCA (Recycled Coarse Aggregate) has high water absorption due to the cement paste from old concrete. It will result in the inferior material properties of recycled aggregate concrete. Presently, the mix design with RCA was developed to get the desired amounts fly ash and recycled aggregate.

[PDF] COMPRESSIVE STRENGTH OF CONCRETE WITH FLY ASH

Results showed that with the addition of nanosilica compressive strength of concrete was increased but workability was decreased with the increase in percentage of nanosilica. The use of fly ash in addition to nanosilica (30% RA+3% NS + 10% Fly Ash) improved both the workability and compressive strength of recycled aggregate concrete (RAC).

Using Microwave Heating to Completely Recycle Concrete

in the coating layer of the original coarse aggregate (OCA) surface and cement matrices at the interfacial transi-tion zone (ITZ), which is the weak part of concrete. Thus, recycled coarse aggregate (RCA) can be recovered for concrete structures because the mechanical performance of the concrete is improved, as shown in gure 2(a) Fi and Figure 2(b)

Sulfate Resistance of Recycled Aggregate Concrete with GGBS

In this new type of concrete, recycled aggregates from construction and demolition (C&D) waste were used as coarse aggregates, and granulated blast furnace slag (GGBS) and fly ash-based geopolymer were used to totally replace the cement in concrete. This study focused on the sulfate resistance of this geopolymer recycled aggregate concrete (GRAC).

Recycled Aggregates in Concrete • Aggregate Research

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.

Recycled Aggregate - an overview

Recycled aggregate is defined as aggregate resulting from the processing of inorganic or mineral material previously used in construction (BS EN 12620, 2013; MPA, 2013). When consisting mainly of crushed concrete, it may be classified as recycled concrete aggregate (RCA).

Mechanical and Durability Properties of Recycled Aggregate

The reutilization of waste concrete and fly ash produced by power plant is one way to develop green concrete. The addition of fly ash in recycled aggregate concrete has two methods, named equivalent replace and super-substitute technique.

The Effect of Recycled Coarse Aggregate and Industrial Wastes

the ability of using the recycled aggregate and industrial wastes as replacement materials in concrete is studied. Silica fume and fly ash are partially used as replacement materials instead of cement with different percentages. The normal aggregate is replaced with recycled aggregate by different percentages.
