Characteristics Of Recycled Concrete

Liquefaction characteristics of recycled concrete ...

Current studies primarily focus on the physical properties and shear strength responses of C&D materials. In this study, the dynamic behaviors (dynamic stress-strain behavior and liquefaction resistance) of recycled concrete aggregate (RCA) and quartz sand in an undrained condition were investigated through cyclic triaxial tests and compared.

Mechanical Properties Of Recycled Aggregates Concrete

Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests. Recycled concrete aggregates contain not only the original aggregates, but also hydrated cement paste. This paste reduces the specific gravity and increases the porosity compared to similar virgin aggregates.

(PDF) Strength Characteristics of Ternary Blended Recycled ...

characteristics of ternary blended recycled aggregate concrete. The influence of foundr y sand, flyash and glass powder on recycled aggregate concrete was studied and the optimum mix

Durability characteristics of recycled aggregate concrete ...

Durability characteristics of recycled aggregate concrete were studied with Rapid chloride penetration test (as per ASTMC1202), sorptivity test and acid test to assess resistance against chloride...

Impact of aging on leaching characteristics of recycled ...

Aug 01, 2016 · The focus of this study was to evaluate the effects of stockpiling (aging) on leaching of elements in recycled concrete aggregate (RCA) that may contribute to tufaceous constituent formation. Speciation and leaching controlling mechanisms of these …

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

with high quality, which primarily depends on the characteristics of crushed demolished concrete. Keywords: recycled aggregate concrete, construction and demolition waste, concre-te properties, research. 1. INTRODUCTION Recent floods, that struck our our country and the region, have caused widespread damage, among

Leaching Characteristics of Recycled Asphalt Pavement: RAP ...

paper considers the application of waste aggregates to lean concrete, based on basic mechanical property tests and environmental toxicity. Compared with natural aggregates, waste aggregates derived mainly from recycled concrete have low specific gravity and high water absorption characteristics.

STRENGTH CHARACTERISTICS OF CONCRETE MADE WITH …

100 % with recycled coarse aggregates 150 × 150 × 150mm, Beam and Cylinder moulds were used for casting. Keywords: Recycled Aggregates, Compressive strength, Fresh Concrete, Waste management. 1.0 INTRODUCTION As we know that concrete is the main construction material across the world and the mostly used in all types of civil engineering works.

Characteristics of Aggregates - Civil Snapshot

The characteristics of the aggregates influence the properties of the concrete. Weak, friable, or laminated aggregate particles are undesirable. Aggregates containing natural shale or shale like particles, soft and porous particles, and certain types of chert should be especially avoided …

Durability And Performance Characteristics Of Recycled ...

The recycled concrete mixes contained 100% recycled aggregate and natural fine sand, while the normal concrete mixes contained all natural coarse and fine aggregates. Table 1.

Effects of Recycled Aggregate Characteristics on ...

Apr 01, 2000 · This study points out the close relationship between several quality indicators of recycled aggregate and the performance of recycled aggregate concrete. Regarding the diversity in quality and composition of the recycled concrete products, three laboratory produced air-entrained-concretes with low, medium and high water-cement ratios and a non ...

Strength Characteristics of Geopolymer Concrete Containing ...

aggregates as recycled aggregates in structural concrete, instead of throwing out as a total waste material. Thus in recent years, the use of recycled concrete aggregate has gained tremendous momentum in constructional engineering. Utilization recycling of …
