“…Self-compacting concrete (SCC) is now widely developed and is a new type of concrete designed to bring many benefits to the properties of structural concrete [1][2][3][4][5]. What differentiates SCC from conventional concrete is the ability to be compacted by its own weight without the need for vibration [6][7][8].…”

“…As a result of their high chemical reactivity and the fact that they act as nuclei, around which the products of the cement hydration process grow, the nanoparticles are nano-filler of the concrete microstructure, which effectively reduce undesirable calcium hydroxide. They also create additional amounts of the C-S-H phase in the concrete structure [15]. Therefore, they improve the physical properties of concrete by reducing, among others, porosity [16] and permeability [17], as well as increasing the corrosion resistance of the concrete [18].…”

Abstract. Due to the new challenges posed to engineering constructions, as well as the principles of sustainable development, many laboratories around the world are carrying out works to improve the basic structural material that is concrete. There has recently been a lot of interest in modifying concrete with nano-sized particles. Literature reviews indicate that their addition significantly improves the physical and mechanical properties of the concrete that was obtained with their use. Until now, there is no knowledge of the effect of nano-additives on the process of destroying temporarily compressed concrete. One test method that enables the parameters that describe the stress failure of concrete to be determined is the acoustic emission method. This work fills the gap in the literature and presents the results of the author's own research on the impact of the use of different amounts of nano-additive TiO2 on the failure process of selfcompacting concrete that was made solely on the basis of granite aggregate.The stress failure of the tested concrete was described using the stress levels (determined using the acoustic emission method) that initiate the cracking σi and critical stresses σcr that delimit the tested process. The descriptors that were used for this purpose are the rate of counts and the average effective value of the acoustic emission signal.

“…SCC decreases the risk of poor workmanship during casting and compaction of concrete. Moreover, economic efficiency, less human work, more freedom to designers and lowering noise level on the construction site are other advantages of using SCC [3]. PET is a kind of polyesters made of the ethylene glycol and terephtalic acid's composition and its chemical name is "polyethylene terephthalate".…”

Abstract. This study evaluates the effect of self-consolidating concrete (SCC) containing waste polyethylene terephthalate (PET) granules on the fresh, mechanical and water absorption properties. Fine aggregates were replaced from 0% to 8% by PET granules. The fresh properties of SCC containing PET granules were determined using slump flow and V-funnel flow time tests. The compressive and splitting tensile strength were evaluated. The results indicated that utilization of waste PET granules in production of SCC could be an effective way for recycling purpose. The maximum amount of PET replacement should be limited to 5%. Exceeding 5% of PET content may result in an increase of V-funnel flow time to overpass the limiting value, decrease in strength. The production of high performance SCC containing 5% PET granules satisfies all the requirements for SCC with satisfactory outputs.
