First published in the March 2017 issue of Quarry Management as The Fourth Industrial Revolution. By Sören Schramm, regional product application manager for aggregates, Trimble. While some argue about whether we are in a new industrial revolution, it is clear that the era of the digital enterprise or 'Industry 4.0' is upon us.

Recently, some researchers have tried to apply MICP to improve RA properties. Several scientists (Lu et al., 2022; Ouyang et al., 2022) investigated RA modification by applying MICP, and their results confirmed the effectiveness and feasibility of microbial modification.Wang et al. (2017) applied MICP and found that water absorption of RAC for 6–8 mm aggregate …

ADVERTISEMENTS: After reading this article you will learn about the rock aggregates and its suitability. Rocks can be crushed and graded to make aggregate which can be added to a bonding material like cement to form concrete, or bitumen to serve as a road stone. Various civil engineering works need different grades of aggregate. The […]

HISTORY. The concept of size-based separations by chromatography was first speculated by Synge and Tiselius, [] based on the observation that small molecules could be excluded from the small pores of zeolites as a function of their molecular size. [] The term "molecular sieve," coined by J. W. McBain [] to describe this property of zeolites, was …

1. Introduction. Soil aggregate stability refers to the resistance of soil aggregates to breakdown against disruptive forces, and is critical to regulate soil processes and function (e.g., water infiltration, runoff and erosion, seed emergence and root growth, carbon sequestration) (Annabi et al., 2017, Wu et al., 2018, Ma et al., 2022, Yudina and Kuzyakov, 2023).

By replacing coarse aggregate as well as fine aggregate with waste plastic known as green innovation. As the years go by, waste plastic increases day by day, since most of the plastic used by human is non-bio-degradable. The idea behind this review is to identify research done by the researchers who uses recyclable material such as plastic ...

Soil aggregate fractionation was performed based on the wet-sieving method described by Six et al. (1998). Accordingly, bulk soil was separated into macroaggregate (2000–250 μm), microaggregate (250–53 μm), and silt-clay (SC) (<53 μm) fractions (Fig. 1). The fraction >2000 μm was almost negligible and thus not included in our analyses.

The aggregates used in the tests included four coarse aggregates, gravel and stone with both good and bad field performance records and a single fine aggregate that was used for all mixes. One Type I cement was used, but was modified by adding Vinsol Resin and calcined gypsum to produce, respectively, an air-entraining and an expanding ...

Misfolded alpha-synuclein (αSyn) aggregates are a hallmark event in Parkinson's disease (PD) and other synucleinopathies. Recently, αSyn seed amplification assays (αSyn-SAAs) have shown promise as a test for biochemical diagnosis of synucleinopathies. αSyn-SAAs use the intrinsic self-replicative nature of misfolded αSyn aggregates (seeds) to multiply them …

Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.

The aggregate power reached 10.8 MPa after 168 h, owing to the carbonation of calcium silicate in magnesium slag. Calcium carbonate and Calcium-silica gel showed a dense microstructure. 2. The phase and carbon sequestration of MSUA changed notably with the increasing carbonation time. The carbonation product was mainly calcite calcium carbonate.

The thickness of the bamboo aggregate is uniform at 7 mm, while the width is designed in three variations: 6 mm, 9 mm, and 12 mm. Because of the notable density contrast between BCA and crushed stone, BCAs replaced crushed stones at a volume ratio of 3.8:1 and a mixing ratio of 1:1:0.85 for BCA with widths of 6, 9 and 12 mm, correspondingly.

It's worth noting that the specific gravity test can be conducted using different methods, depending on the size of the aggregates being tested. For aggregates larger than 10 mm or 40 mm, a specific method is employed, while smaller aggregates, less than 10 mm in size, undergo a Pycnometer test.
