Incorporation of coal gangue in the concrete mixes can realize utilization solid waste and reduce extraction/use natural aggregates. To improve mechanical properties concrete, this paper studies use steel fibre together with coarse aggregate, fine aggregate/sand various mixes. The effect volume dosages different levels replacing nature aggregate river sand aggregates on compressive strength was...

Aggregates are natural materials of great demand. They directly used for construction or as constituents ready-mixed concrete asphalt products, and they appear an index the economic activity a country. Distance between quarries demand points controls price high place-value products such aggregates. Their potential exploitation depends on factors geology, environmental heritage protection laws, ...

The increase in the number of road construction projects has led to an need for pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year asphalt, as well aggregate. Seeing these conditions, is necessary anticipate use waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used aggregate Asbuton (Buton Island ...

The purpose of this study was to evaluate the influence anti-stripping green additives on behaviour a fresh binder. Firstly, adhesiveness (spectrophotometric method) and affinity (rolling bottles binder with penetration grade 50/70 two types aggregates (natural quarry from different sources) were investigated. results show weak bond stripping between aggregates. Therefore, (named A B) used in t...

Bovine erythrocyte spectrin was found to interact with lysophosphatidylcholine and lysophospatidylserine what was detected by small changes of the intrinsic fluorescence of spectrin. Lysophosphatidylethanolamine in contrast to its diacyl, natural counterpart did not affect the intrinsic fluorescence of spectrin at all. Dioleoylphosphatidylethanolamine induced distinct changes in the intrinsic f...

Aggregation of the nanoparticles is a natural phenomena due to various biological and physical parameters but these aggregates are highly unstable. If would have been stable then it might be useful for some biomedical applications. To study optical properties photothermal heat generation metal nanopartilces, we present forced synthesis small gold nanorods in mixture Dulbecco's Modified Eagle's ...
