The use of recycled aggregates in concrete construction in the Congo today requires appropriate studies to meet the safety and durability requirements of structures, such as Concrete is a composite material made up of aggregates, water, a binder, and optional additives [1]. It is a true artificial rock, one of the most widely used materials Contribution to the Study of Materials Commonly Used in Goma,
The present paper refers to the concrete recycling subject and, more specifically, to a proposal for Greek specifications of recycled concrete aggregates 2.2.2. Tests on Concrete 1) Consistency a) Purpose The consistency of concrete is obtained by the standardized test NF P 18 45 [10]. The purpose of the test is to obtain Concrete Based on Recycled Aggregates for Their Use in

Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause theAggregates Cement

The general crushing and manufacturing process of light concrete, LC, using PET as component in concrete, is shown in Figure 1. Crushing equipment was an electric claw crusher accepting a 76 mm (3′′) MAS. A manual screen with 19 mm (3/4′′), 9.5 mm (3/8′′), and 4.76 mm (no. 4) meshes was used to screen the material.China's demand for Cement, Concrete & Aggregate will continue to grow at about 8% by 2032. China's demand for Cement, Concrete & Aggregate has grown at a fast pace in the past decade. In the next decade, both production and demand will continue to grow. The Chinese economy maintains a high speed growth which has been stimulated by theCement, Concrete & Aggregate Markets in China
The concrete aggregate was chosen due to improvement capillary bonding mechanisms and ceramic presented similar strength compared to the conventional concrete using natural aggregate. Percent of replacement have been used in this study was at 25%, 35% and 45% of the RCA and 5%, 10% and 15% for ceramic, respectively.Influence of Aggregate Grain Size on the Formulation of Sand Concrete in the Construction Industry in CongoInfluence of Aggregate Grain Size on the Formulation of Sand Concrete

This paper reviews specific technical and eco-efficiency performance issues in using glass waste as an aggregate in the production of concrete. Eco-efficiency is a relatively modern tool in the pursuit of sustainability. Eco-efficiency is the concept of maximising the benefits from the use of non-renewable resources while minimising the Concrete made with large-size recycled aggregates is a new kind of recycled concrete, where the size of the recycled aggregate used is 25–80 mm, which is generally three times that of conventional aggregate. Thus, its composition and mechanical properties are different from that of conventional recycled concrete and can be applied Sustainability Free Full-Text Discrete Element Simulation MDPI

Due to the presence of old mortar (OM) and interfacial transition zone (ITZ), recycled concrete aggregate (RCA) is inferior to natural aggregate (NA). The purpose of this paper was to study the effect of accelerated carbonation on the macro-properties and micro-properties of RCA under different pressure (0.05, 0.15, 0.30 MPa).

Most recycled concrete is used as aggregate in road sub-base. When well cleaned, the quality of recycled concrete aggregate is generally comparable to virgin aggregate. The possibilities for use are equally comparable although the use of crushed concrete in new fresh concrete is rare. Recycled aggregate accounts for ~6% to 8% of aggregateThe demand for sustainable construction materials has driven the exploration of various innovative approaches to enhance the properties of concrete for reducing its environmental impact. The present study examines the effects of incorporating recycled concrete aggregate (RCA), slag cement, alccofine, and glass fibers into Experimental Investigation on Ternary Blended Recycled Aggregate
