The ball-shaped crystals, and regular-prism-shaped crystals were found on top of bush-like long crystals. Two types of CdO self-organization aggregates were also observed, that is, regular circular-shaped dense aggregate and long-chainshaped aggregate. The self-organization aggregates were composed of numerous submicron CdO grains. The relationship between self-organization aggregates and surface defects of virgin N 1

Abstract:
Bitumen emulsion asphalts, especially those incorporating marginal and secondary aggregates, are energy efficient, environment friendly, and sustainable alternatives to hot-mix asphalts. This study set out to compare engineering properties of a bitumen emulsion asphalt composed entirely of virgin aggregates with another composed of 55% reclaimed asphalt and 45% virgin aggregates. The aggregates were bound with a slow setting cationic bitumen emulsion composed of 65% base bitumen and 35% water. Marshall specimens molded at varying pre-mix water and bitumen emulsion contents were cured in molds

This paper presents the findings of an investigation on the influence of recycled aggregate concrete (RCA) as a substitute for virgin coarse aggregate in the compressive strength of `plain concrete. Recycled aggregate concretes were produced together with virgin coarse aggregates and subjected to empirical tests which include grading, specific gravity, bulk density, water absorption, aggregate impact value (AIV) and aggregate crushing value (ACV) to ascertain their performances. Mix design was carried out for grade 30 concrete according to DoE (1975) and RCA percentages of 0, 25, 50, 75, and 1

Abstract:
Hot-mix asphalts exposed to hot weather and high traffic volumes can display rutting distress. A material that can be used to increase the stiffness of asphalt binders is gilsonite. On the other hand, from an environmental point of view, the virgin natural aggregates of asphalt mixtures can be replaced with recycled concrete aggregates. For these reasons, this study modified the asphalt binder with gilsonite by wet-process to improve rutting resistance, and replaced (by mass and volume) part of the coarse fraction of the aggregate with recycled concrete aggregate in two hot-mix asphalts with d

The results of the laboratory and in situ tests show that asphalt mixtures containing granulated EAF slag aggregates perform as well as mixtures containing only VA. In ad

Abstract:
Pervious concrete is a mixture of cement, coarse aggregate mixed with water. The absence of fine aggregate helps increase the voids and water can pass through these gaps and reaches to ground level. The use of recycled coarse aggregates from construction and demolition is a sustainable solution with many environmental benefits and also reduces the number of virgin aggregates to be created, hence reducing the extraction of natural resources. This paper reviews the research developments of pervious concrete by replacing natural aggregates with different percentages of recycled coarse aggregate.

<strong>Abstract</strong> Due to the increasing demolition of existing civil engineering infrastructures, as well as the building industry's sustainability and carbon reduction ambitions, the necessity to use recycled aggregates from construction and demolition wastes for new projects cannot be overstated.

Abstract:
Concrete recycling to produce aggregates is crucial in reducing the demand for virgin materials in the construction industry, particularly for the most widely used building material—concrete. A potential solution to enhance the quality of recycled aggregates involves the removal of the adhered cement paste from their surfaces. In this study, samples of industrial demolished concrete were selectively separated into recycled sands and aggregates while removing the hydrated cement paste. The recycled materials were characterized to assess their suitability for structural concrete production. The
