Green concrete are generally composed of recycling materials as hundred or partial percent substitutes for aggregate, cement, and admixture in concrete. To reduce greenhouse gas emissions, efforts are needed to develop environmentally friendly construction materials. Using of fly ash based geopolymer as an alternative binder can help reduce CO2 emission of concrete. The binder of geopolymer con...

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology in the last two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. Marble Sludge Powder (MSP) can be used as filler and helps to reduce the total voids content in co...

Drilling ever deeper, and thus in increasingly difficult conditions, is associated with restrictive requirements that must be met by cement slurries. This implies the need to use advanced, innovative measures will significantly improve performance parameters of slurry stone. Due its unique properties, an admixture nanosilica improves properties stone allows for appropriate zone insulation. The ...

Earth-moist concrete mixes are the starting substance for the mass production of concrete products like pipes, slabs, pavement stones and curb stones. The working properties of earth-moist concrete (EMC), caused by its dry consistency, are advantageous. So, in comparison to normal-weight concrete, the consistency of EMC allows for direct stripping of concrete products after filling and vibratin...

The article presents a study of changes in the mineralogical composition cement when adding microsilica different concentrations using diffractometer DRON-3 with СuCa-radiation, β-filter. X-ray phase analysis on semi-quantitative basis was carried out powder sample diffractograms method equal weights and artificial mixtures. work examines effects at microstructural level. aim to improve physico...

Currently, most concrete industries use conventional cement (Ordinary Portland Cement) as a binding material which involves natural resource depletion, colossal CO2 emissions, and huge energy supply. The present study addresses this critical issue by using stone dust (sun-dried calcinated) water treatment sludge to replace partly in M20-grade production. environmental impact of ready-mixed (RMC...
