AB  - Self-compacting concrete (SCC) contains fine mineral fillers such as limestone powder. The idea
of this study was to partially replace limestone with waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert and to compare the properties of produced concrete samples. Fresh concrete properties included: slump-flow, t500, V-funnel time, L-box ratio, segregation ratio, density, and entrained air content. Hardened concrete was tested for compressive, flexural and bond strengths, ultrasonic velocity, dynamic elasticity modulus, dynamic Poisson’s ratio, and microstructure. Flowability and segregation increased, while bulk density, compressive and flexural strength, dynamic elasticity modulus and ultrasonic velocity slight declined. Times t500 and V-funnel time, L-box ratio and entrained air changed insignificantly. Considering that all properties should remain or improve in case of waste valorization and the criteria should set to satisfy requirements for SCC, this study proved that all mixtures can be used for structural applications.

AB  - The production of durable concrete with a high content of supplementing cementitious materials and recycled aggregate presents a step towards sustainability in the concrete industry. The paper presents the findings of the study, conducted on four series of concrete with self-compacting properties, which embodied recycled concrete aggregate, as a substitution for natural sand and gravel. Besides, this concrete possessed high content of fly ash, therefore qualifying as ecological (green) one. Particle packing method was used in the design of this concrete. Fresh properties included: density, slump flow, V-funnel, L-box and temperature, while compressive and tensile strengths were evaluated in the hardened state. Although certain difficulties in the application were recognized concerning the fast loss of workability in the fresh state, all of the tested mixtures exceeded the requirements of hardened structural concrete.

AB  - Self-compacting concrete (SCC) typically contains a certain content of very fine mineral fillers such as limestone powder. The idea of this study was to partially replace limestone with elemental waste sulfur since it is hydrophobic, insoluble in water and therefore chemically inert in concrete mixtures. Properties of conventional SCC with limestone and several compositions with different sulfur content were compared. Hardened concrete was tested for compressive, flexural and adhesion strengths, dynamic elasticity modulus, specific electrical resistance, density, microstructure and infrared thermography. Results showed slight decline in compressive, flexural and adhesion strengths as well as in dynamic elasticity modulus. Specific electrical resistance and density were higher for samples with sulfur. SEM analysis indicated slight porosity increase for the sample with sulfur. Infrared thermography was applied as a fast method for detecting internal deformations. Having in mind that all properties should remain or improve in case of waste valorization and the criteria should set to satisfy requirements for SCC, this study proved that all mixtures can be used for certain structural applications.
