recycled concrete aggregate (RCA) in field implementations (Surya ). RCA is mostly being used in granular bases, embankments, sound barriers, fills, and so on. (Kim , Gabr ). Laboratory investigations on properties of concrete made with RCA has proved to be an issue of great interest during the past decades. However, there is a

The effect of add-ing cellulose-recycled fibers on mechanical and thermal properties of cement paste is studied in Bentchikou et al. [2].

Recycled concrete aggregate (RCA) collected from the demolition of old reinforced concrete structures can be reused to prepare structural and non-structural concrete, thereby protecting the environment by preserving natural resources. This study explores RCA’s use, collected from the crushed concrete of different building projects in Riyadh, to manufacture fresh self-compacting concrete (SCC

The brick specimens are prepared by using 100% natural sand, which is then replaced by RFA at 25%, 50%, 75%, and 100% by weight of natural sand. Research parameters, such as dimension, compressive and flexural strength, density, and water absorption, are adopted to evaluate the physical and mechanical properties of the brick specimens.

In order to study the effect of nano-strengthened RAs on the mechanical properties, structural properties and the microstructure in ITZs of RACs, the RACs with the similar fluidity were mixed according to the mix proportion shown in Table 3 The reference concrete was mixed by the original RAs and the other three concretes were produced by the

EFFECT OF SILANE TREATMENT ON THE MECHANICAL PROPERTIES OF POLYMER CONCRETE MADE WITH RECYCLED PET RESIN AND RECYCLED AGGREGATES K P Singh1, Raman Bedi2, Aditya Bakshi3 1, 2, 3, Dr B R Ambedkar National Institute of Technology Jalandhar, India ABSTRACT. In present work, polymer concrete was made using resin obtained from

Recycled concrete aggregate, which is obtained from C&D waste, is currently being considered as an alternative aggregate for structural concrete. Recycled aggregate concrete (RAC), an ecofriendly concrete produced by partial or full substitution of natural aggregates with recycled concrete aggregates in a concrete mix, has drawn much attention

The present investigation mainly focuses on the influence of different fibers on mechanical and other properties of concrete made with 50% of recycled coarse aggregate (RCA) as well as concrete with 100% natural aggregate.

The current study aims to investigate the influence of rubber surface treatment on the mechanical, transport, and thermal properties of concrete. In the concrete, 8% of natural aggregates by volume have been replaced with rubber aggregates pretreated with water (H 2 O), calcium hypochloride [Ca(ClO) 2 ] and sodium hydroxide (NaOH) for different

Mechanical properties of recycled aggregate are primarily dependent on the quality of the original cement mortar present in the aggregate, and also, as in the case with natural aggregates, depend on a number of other factors - the type of the original aggregate, structure, shape and size of grains, aggre-gate grading and so on.

Mechanical Properties of Recycled Ultra-High Durability Concrete The mechanical properties of UHDC and R-UHDC mixes were determined at 7, 28, 56, 90, and 120 days. To determine the hardened concrete density, compressive strength, and flexural strength of concrete, prisms of size 160 × 4 × 40 mm were prepared.

Jul 07,  · This paper reports on the performance of concrete made using recycled fine and coarse aggregates. Either natural sand was partially replaced (25, 50,75 and 100%) or only coarse aggregates or both. Compressive and flexural strengths were compared with those of concrete made using natural aggregates up to the 90 days of age.

This paper studied the mechanical properties of concrete with cement partially replaced by recycled clay-brick-powder. Four variables (water/cement ratio, sand ratio, replacement level and average particle size of clay-brick-powder) were considered. Each variable had four levels. By using the orthogonal experimental design method, total 17 mixes, including one normal cement concrete as

The concrete made by replacing cement and adding different fiber dosage reveled positive result showing increase in the mechanical properties of concrete when compared with the control one. Marked strength has been achieved in the concrete made by replacing cement with 10% of fly ash and by adding 1% of hybrid fibers.
