In current construction, there are still areas that utilize natural materials such as aggregates from rivers construction materials, one of which is in the Dumoga, Bolaang Mongondow, North Sulawesi. The communities this area use river concrete mixture development process. purpose study was to provide information public about material characteristics and quality using coarse fine Ongkak River, D...

The feasibility of using EAF slag aggregate, fly ash, and silica fume in pavement Electric Arc Furnace Slag Concrete (CEAFS) is the focus this research. aggregate volume stable suitable for use concrete, according to findings testing. was utilized replace natural coarse aggregates CEAFS mixes. created by blending 50% crushed stone with aggregates, ash (FA) (SF) partially replacing cement at con...

Several short peptide sequences are known to self-assemble into supramolecular nanostructures with interesting properties. In this study, coarse-grained molecular dynamics is employed to rapidly screen all 400 dipeptide combinations and predict their ability to aggregate as a potential precursor to their self-assembly. The simulation protocol and scoring method proposed allows a rapid determina...

Abstract—This paper presents the experiment results of investigating the effects of adding various types and proportions of fibre on mechanical strength and permeability characteristics of recycled aggregate concrete (RAC), which was produced with treated coarse recycled concrete aggregate (RCA). Two types of synthetic fibres (i.e., barchip and polypropylene fibre) with various volume fractions...

This paper reports the strength behaviour of concrete containing three types of recycled polyethylene terephthalate (PET) aggregate. Results are also analysed to determine the PET-aggregate’s effect on the relationship between the flexural and splitting tensile strengths and compressive strength and to know whether the relationships between compressive strength and other strength characteristic...

Since the aggregate is 80 % of the total volume of the concrete and mortar, the characteristic properties of the aggregate affect the fresh and hardened properties of the concrete and mortar [1]. The characteristic properties of the aggregate such as the shape, the size and structure affect the properties of the fresh concrete and the mortar like workability, settlement, pumping and segregation...
