Kernel Metadata Declaration — on demand

ISO 26324 asks a DOI Registration Agency to produce a Kernel Metadata Declaration for every DOI it issues. Give any DOI: its public record becomes a record in the Smart Scholars DOI Metadata Format 1.0, checked against every rule, and declared as the Kernel XML.

✓ Meets every rule of the format

The record below is complete and every controlled value is a DOI Attribute Value Set 2.3 spelling. The Declaration on the right follows DOIMetadataKernel.xsd element by element.

        "value": "In the recent development in civil engineering geopolymer is a binder like cement used to produce concrete to get sustainable durable concrete.The worldwide consumption of concrete is estimated to be aboutbillion tons per year. Due to the increase in infrastructural developments, the demand for concrete would increase in the future. The main objective of the study is to look into the shear behaviour of hybrid fibre reinforced geopolymer concrete beams. Test specimens of 1200 mm ×150 mm × 100 mm size were used for the study. A 20-30% of Fly ash by the mass was replaced by GGBS. The variable used were percentage of steel fibre by volume fraction, viz., 0.0%, 0.5%, and 1%, and basalt fibre volume fraction, viz., 0.0%, 0.15%,and 0.3%. The concentration of sodium hydroxide was 12 Molar and 14 Molar in geopolymer concrete. For curing, temperature was fixed as 600C for 24 hours. The geopolymer specimens were cured by using steam curing chamber. The specimens were cured after the rest period of three days. A trail and error process was used to obtain proper mixture proportion for geopoymer concrete. The specimens were tested after the age of 7 days. The obtained results of Fly ash and GGBS -based hybrid fibre geopolymer concrete (F&GHGPC) specimens were compared with the only Fly ash-based hybrid fibre geopolymer concrete (FHGPC) specimens. Test results show that first crack load, ultimate load, energy absorption capacity, experimental shear strength and ductile characteristic of F&GHGPC geopolymer concrete specimens were higher than the FHGPC geopolymer concretespecimens",
