In order to determine the relative proportion of different particle sizes available in an aggregate mix, sieve analysis or gradation test is to be performed. In this test, the sieves are arranged in descending order of their opening sizes and are stacked over each other as shown in Fig. 5. Fig. 5: Stack of Sieves.

In simpler words, grading is a way of using different sizes of aggregate in a concrete mix to fill the space that the bigger particles can't fill. Gradation of aggregate speaks about the particle size distribution in a sample of aggregate. Types of gradations in aggregate. 1. Well-graded (or) Dense graded aggregate
In this research, pulsed power was applied to produce high grade recycled aggregate due to its better ability to remove cement paste from the aggregate. Removal of cement paste from aggregate to produce high grade RCA consists of two mechanisms, as shown in Fig. 5. When concrete is exposed to high-voltage discharge, the dielectric …
Road construction consumes great amounts of high-grade natural resources. Using low-grade natural rocks or some solid wastes as substitute materials is a hot topic. Considering this, the feasibility of using low-grade granite aggregate, solid waste-based filler (desulphurization gypsum residues, DGR …

This view is consistent with that suggested for the microstructure of the ultra-high-performance concrete prepared by Zhang et al. [28] using fine recycled concrete aggregate (FRCA: 0–5 mm) and natural fine aggregate (NFA: 0–5 mm), as shown in Fig. 1 (a). ITZ 1 lies between the NFA and new cement matrix, ITZ 2 lies between the NFA and …
The L.A. Abrasion Test is a mechanical measure employed globally but predominantly in the United States. It quantifies the degradation and abrasion resistance of aggregate materials, foundational for constructing high-grade Hot Mix Asphalt (HMA). The test's apparatus (Figure 1) is composed of a rotating steel drum encapsulating coarse ...

2.2. Well-Graded. Well-graded aggregates, also known as continuously graded aggregates, contain a balanced distribution of particle sizes, including all or most of the required sizes. This type of grading is preferred in general construction projects, as it results in a mix that is dense and well-compacted.
