“…However, the findings of the current investigation (Table 6) show that, in general, the increase of the ECat in the binder leads to an increase in the capillary water absorption of concrete, which has also been previously seen elsewhere for high levels ECat incorporation in the binder above 20% [35,56]. Therefore, this effect emphasizes the assumption mentioned above, that the occurrence of the pozzolanic reaction of ECat, when it is present in the binder beyond a particular content, might be limited by the absence Ca(OH) 2 due to the small amount of clinker.…”

“…The literature review also showed that when ECat partially replaced cement by up to 15-20% (by mass), it enhances both early and long-term strength of cement-based materials [34][35][36]. Moreover, it has also been shown that up to 10-15% of cement replacement by ECat has no adverse effect on the cement-based materials durability [35,37,38]. From a technological viewpoint, the ECat's main disadvantage as a pozzolanic material is the workability reduction that it promotes on the fresh state of cement-based materials, as its content in the binder increases due to its high surface area with water affinity [34,36,39].…”

Large-scale recycling of new industrial wastes or by-products in concrete has become a crucial issue for construction materials sustainability, with impact in the three pillars (environmental, social and economic), while still maintaining satisfactory, or improved, concrete performance. The main goal of the paper is to evaluate the technological feasibility of the partial, or total, replacement of fly-ashes (FA), widely used in ready-mixed concrete production, with spent equilibrium catalyst (ECat) from the oil-refinery industry. Three different concrete mixtures with binary binder blends of FA (33.3% by mass, used as reference) and of ECat (16.7% and 33.3%), as well as a concrete mixture with a ternary binder blend with FA and ECat (16.7%, of each) were tested regarding their mechanical properties and durability. Generically, in comparison with commercial concrete (i) 16.7% ECat binary blended concrete revealed improved mechanical strength and durability; (ii): ternary FA-ECat blended binder concrete presented similar properties; and (iii) 33% ECat binary blended concrete has a lower performance. The engineering performance of all ECat concretes meet both the international standards and the reference durability indicators available in the scientific literature. Thus, ECat can be a constant supply for ready-mixed eco-concretes production, promoting synergetic waste recycling across industries.

Abstract. Technology of concrete has been advanced recently to improve the properties of concrete. Utilization of ash as the substitute of cement or filler of concrete also indicates good result in compressive strength concrete in certain amount. Harnessing the bacteria for self-healing concrete has also been successfully performed in order to maintain the destruction of the concrete by itself. Past research indicated that bacteria can be beneficiary to improve the compressive strength, absorption, permeability, and so on. In this paper, Bacillus Altitudinis was extracted from the karst (source from the limestone mountain) and bred through liquid media to be impregnated inside the volcanic ash. The impregnated bacteria in volcanic ash were used as the filler to the concrete mixture with the proportion of filler varied from 1%, 1.5% and 2% to the weight of cement. Mechanical properties of the concrete specimen showed that the compressive strength reached its best when the filler proportion was 1.5%. The absorption referred analogously to the increment of compressive strength due to the success of filling the void inside the concrete. Based on compression test to all the concrete specimens, there was enhancement about 18% and the average absorption can be abated around 23%. Future research due to some drawbacks turning up is the need of developing another media for bacteria to live and making sure the exact amount of bacteria impregnated to the media so that the desired advance of concrete compressive strength can be acquired.

“…Mažesni NK kiekiai gali būti naudojami kaip pucolaninis priedas gaminant itin aukštos kokybės cemento medžiagas (Castellanos et al, 2015). Antiohos et al (2006) pastebėjo, kad NK, gautas iš Graikijos "Hellenic Petroleum" naftos perdirbimo gamyklos, įgyja didesnį pucolaninį aktyvumą papildomai išdegtas 650 °C temperatūroje.…”
