“…Recycled aggregate has different properties than natural aggregates, therefore they behave differently in concrete mixtures [30]. Compressive strength, tensile strength and modulus of elasticity are the most effective properties of concrete affecting its performance properties.…”

Research on the use of construction and demolition waste as recycled aggregate for the production of new concrete has confirmed that they are environmentally friendly and constitute an alternative method of waste management. However, contrary to conventional concrete, no large applications of concrete made with recycled concrete have been made and there is still the literature studies of recycled aggregate properties are different, which indicates the need for further research on the properties of cements from waste. This paper presents and compares the results of a laboratory study on the properties of ordinary concrete (BZ), high-strength concrete (BWW), recycled aggregate concrete (REC). The tensile and compressive strength, modulus of elasticity of these concentrates were marked. The research results proved that the compressive strength of the concrete with recycled aggregate, compared with high-performance concrete, is much lower, but only slightly lower than for ordinary concrete. In turn, the tensile strength of the concrete with recycled aggregate is lower than that of high-performance concrete and ordinary concrete. These values, in the case of the compressive strength are as follows: REC -52MPa; BWW -68MPa; BZ -25MPa, whereas for the tensile strength, they reach: REC -4 MPa, BWW -6 MPa, BZ -5.1 MPa. Statistical analysis showed that the given parameters of the analysed concretes are indeed statistically different. Obtained results indicate that recycled aggregate may be aggregate of standard value and good mechanical properties, even better than of ordinary concrete. The application of recycled aggregate is considered to be a new approach in balanced construction and a superb solution to protect the environment.

“…The shrinkage behavior of rubberized concrete was investigated before as mentioned by Elzokra et al (2020). Yung et al (Yung et al, 2013) concluded in their study on the durability properties of self-compacted concrete including rubber powder that the shrinkage in RBC is small but larger than the control one, furthermore, the increase in shrinkage is directly proportional to the amount of rubber.…”

In recent years, extensive research has focused on investigating rubberized concrete as a structural material due to its enhanced properties, including increased ductility, improved energy dissipation, and higher damping ratios. Additionally, rubberized concrete contributes to sustainable development by recycling non-biodegradable waste and reducing the use of natural aggregates in concrete mixtures. However, its performance in retrofitting existing structures remains unclear and requires thorough investigation before it can be widely implemented in construction activities. The main objective of this research is to evaluate the seismic performance of reinforced concrete buildings strengthened with rubberized concrete jackets under severe earthquake excitations. To achieve this, laboratory tests were conducted to assess the properties of high-performance, self-compacting rubberized concrete mixes with various rubber content levels. Additionally, finite element models of reinforced concrete retrofitted with these mixes were analyzed using nonlinear response history analysis to compare their performance against control models. The results of this experimental work indicate a significant reduction in the mechanical properties of rubberized concrete. However, there is a considerable improvement in the damping ratio, which enhances the energy dissipation capacity of the structures. This improvement contributes to an increase in damping energy and a reduction in hysteretic energy, suggesting that rubberized concrete jackets can enhance the seismic resilience of reinforced concrete buildings.

“…Water absorption and water permeability is such a parameter which shows the transport way of water but also provide water resistance capacity of alkali activated binders and concretes. Researchers studied the influence of liquid alkali activator and use of silica fume (SF) on durability and microstructural properties of AASC pastes [49,[71][72][73][74][75]. The linear regression of porosity versus compressive is shown in Fig.…”

This paper describes a review of the state-of-the-art research carried on the fresh and hardened properties of Alkali Activated Binders and Concretes. Though, many research have been carried out in the recent times on alkali activated binders, few key parameters still remain unattended, that restricts the commercial application of AAMs to the general construction activities. Fresh properties, mechanical strength and durability performance of Alkali activated concrete with various Alumino silicates as base materials is mentioned. An essential parameter of Alkali activated concrete is the concentration of alkaline solution on which various properties like mechanical strength, setting time and durability depends. Influence of wide range of concentrations from 6 to 16 M on these properties are studied and reported in this paper. This paper mainly concentrates on properties of readily available base materials such as Fly ash and Slag and the means to improve their performance through the use of various industrial and agro-based byproducts as additives. Problems pertaining to practical applicability of AAMs to general construction activities are also highlighted.
