The depletion of aggregate-related natural resources is the primary concern of all researchers globally. Recent studies emphasize the significance of recycling and reusing various types of natural or by-product material waste from industry as a result of the building industry's rising demand for aggregate as the primary component in concrete …

The coarse aggregate is poorly graded but more of uniformly graded because the co-efficient of curvature lies between 1 and 3.This confirms that the coarse aggregates possess little or no fine sized aggregate because rain or water run-off within the study years have negligible impact on the coarse aggregate over the study years.

1. Introduction. Natural crushed rocks or stones are commonly used as coarse aggregates in the production of concrete. Various types of natural rocks (e.g., …

Several studies have been carried out to evaluate the effect of replacing natural aggregate (NA) with recycled aggregate (RA) on mechanical and physical …

Moreover, the condition of water spalling the asphalt-aggregate interface is characterized by a change in the mass of asphalt film before and after boiling. It can be …

Recycled aggregates include coarse recycled aggregates (CRA) with a typical particle size range of 4.75–31.5 mm and fine recycled aggregates (FRA) between 0.16 and 4.75 mm [27]. Since RA obtained from CDW contains hardened cement paste or mortar and the surface of RA is rough, many micro-cracks will be generated during the …

Evaluating compressive strength of concrete made with recycled concrete aggregates using machine learning approach. Construct. Build. Mater., 323 (2022), Article 126578, …

Objectives: Normal sleep is crucial for brain health. Recent studies have reported robust associations between sleep disturbance and various brain structural and functional traits. However, the complex interplay between sleep health and macro-scale brain organization remains inconclusive. In this study, we aimed to uncover the links …

1. Introduction. Since the invention of Portland cement (PC) in 1824, cement and concrete have played pivotal roles in advancing human society. However, rapid urbanisation and the expansion of the construction industry have led to the substantial depletion of natural resources, specifically the coarse and fine aggregates employed in …

This research work aims to compare the strength and fracture mechanics properties of plain concretes, obtained from different coarse aggregates. During the …
