The chemical composition of mollusc shells is comparable with those of natural aggregate such as limestone (Table 6). Just like most natural aggregates, the major chemical compound in mollusc shell is calcium oxide. The high calcium oxide content of seashell suggests that seashell could be an inert material in concrete similar to …

The mechanism determining the influence of aggregate chemical composition on the speed of emulsified asphalt mortar demulsification was investigated, and an emulsified asphalt …
Based on testing technology of SEM/EDS, microcosmic interfacial transition zone structure of hydraulic concrete of different aggregates were studied, such as limestone, basalt and sandstone. The results showed that used different aggregates in concrete, there were differences in element distribution and variation along the …

The investigation included concrete made by using recycled brick as aggregate. Experimental work included several types of concrete made with the same cement content (385 kg/m3), and same ...
Rock chemical composition in this table is presented as major oxides, which make up for 98% of the overall rock. Other elements are only present in trace …
The addition of MK to the mix with recycled aggregates caused an 84.6% reduction in the Cl− diffusion coefficient, there was also a 40.3% reduction in Cl− penetration and an increase of up to ...
Combined, these results suggest that the chemical composition of lipids (and likely also that of other soil organic matter compounds) governs interaction with their environment, such as accumulation in aggregates or association with mineral soil compartments, and thus indirectly influences their persistence in soil.

The nature of aggregates has an important influence on the behaviour of concrete at high temperature. The aggregates used in concrete are classified into two categories: siliceous (S) and calcareous (C). Most publications and Eurocode 2 Part 1–2 underline concrete containing C aggregates have a better thermal resistance in …
Data on the chemical and mineralogical composition of cement, as well as the chemical composition of aggregates, are provided by the manufacturer and fully comply with the requirements for raw ...
The physico-chemical, mineralogical and microstructural evolutions of these aggregates with temperature were analysed to better understand the instability process of concrete aggregates.
The bulk chemical composition of the different grain size fractions is given in Table 3, expressed as oxides. ... Fe 2 O 3 and MgO, reflect either differences in original aggregate composition, such as the presence of (dolomitic) limestone in the aggregate, and/or relative amounts of binders present in the adhering cement paste ...
Purpose Long-term fertilization is a widely accepted strategy to enhance soil organic (SOC). However, fertilization effects on the stability of aggregate-associated OC remained largely unknown. Thus, stability of aggregate-associated OC was studied through aggregate fractionation, C-mineralization, and 13C NMR analyses. Materials and …
INTRODUCTION. Mineral xide aggregate (MTA) was developed at Loma Linda University, in the 1990s, as a root-end filling material. It is used primarily to seal lateral root perforations[1,2] and as a root-end filling material.[3–6] The use of MTA as a root-end filling material was identified because the material is hydraulic and sets in the presence of water.
Purpose Green manure plays a key role in reducing chemical fertilizer applications and increasing soil organic carbon (SOC) stock. The effects of chemical fertilizer substitution by Chinese milk vetch (MV) on the distribution and composition of organic carbon fractions in macroaggregates and microaggregates and SOC stability …
PCA revealed distinct variations in the chemical composition of OM in aggregate size fractions among the amendment treatments (Fig. S3). While the OM composition of unaggregated silt–clay fractions could be clearly separated by PC1 from those of macroaggregates and microaggregates, CB shifted the SOM structure mainly …
The underlying mechanisms of regulation of the chemical composition and dynamics of different SOM density fractions (DFs) in aggregates in a desert steppe by N and P supplementation are unclear. Here, the chemical composition and organic carbon (C) and N dynamics of various SOM DFs under N and P addition were assessed.
A Pearson correlation analysis was used to determine the relationship between the chemical composition of SOC, soil aggregates, and soil physicochemical …
