“…Segregation resistance is the capability to stay homogeneous during the process of transporting, placing and after placing without tendency to bleed and separation of aggregates from mortar. Similar to any other type of concrete, strength, volume stability and durability of the hardened LWSCC are important in structural applications (Sethy et al, 2016…”

The utilization of natural and artificial lightweight aggregates in lightweight self-compacting concrete (LWSCC) is gaining popularity in research field. Extensive research has been carried out in the past decade all over the world to utilize lightweight aggregates (LWA) in selfcompacting concrete (SCC). LWSCC, which uses renewable aggregates, has great potential to become an alternative material to conventional concrete. The paper is aimed to review the more recent research of physical properties of lightweight aggregates used in developing mix design of lightweight self-compacting concrete. In design, the mix proportion of LWSCC is a crucial factor to achieve the desired fresh and hardened concrete properties. The methods to develop LWSCC mix design with anticipated fresh and hardened concrete are reviewed. Research shows that the mix design LWSCC is preferably proportioned by aggregates packing concept. In addition, discussion on the fresh and hardened concrete properties is made and summarized in this paper. Studies indicate that there is a promising future for the use of lightweight aggregates in SCC as it shows satisfactory filling ability, passing ability, segregation resistance and compressive strength. Research gaps recommendations are then identified through this review to further discover lightweight self-compacting concrete in several aspects, particularly in term of sustainability.

“…As per EFNARC (EFNARC, 2005), these ranges of slump flow come under flow classes of 2 and 3 (SF2 & SF3) and under these ranges, SCC will be suitable for casting columns and slabs. The slump flow was found to be holding an inverse relationship with the successive addition of GGBFS which may be due to the agglomeration of cement particles which can be dispersed by slag particles (Nehdi et al, 2004;Sethy et al, 2016). It was also observed that when an extra amount of slag is added as a partial replacement of cement, lesser amount of superplasticizer is required to maintain desired workability.…”

In the last decades, the utilization of industrial waste like ground granulated blast furnace slag (GGBFS) has proven itself a great asset in the modern construction industry. Aiming at promoting the green housing initiatives, the present study focuses on the study of the influence of GGBFS on the structural performance of Self Compacting Concrete (SCC). In the initial phase of the extensive experimental programme, concrete cubes were prepared with the partial replacements of GGBFS (10%, 15%, 20%, 25% and 30% with cement) and tested against the control mix in order to investigate the associated mechanical properties (compressive strength, tensile splitting strength and flexural strength).At 20% GGBFS replacement, the optimum compressive strength was noted and further addition of GGBFS caused a gradual decrease in the mechanical strength properties. This study further investigates the structural properties like axial load-displacement behavior and failure pattern of reinforced concrete (RC) columns and flexural performance of RC slabs with and without the addition of GGBFS. SCC with 20% GGBFS demonstrated relatively better structural performance, causing the formation of lesser 2 crack width/depth/length as compared to the control mix. An empirical relationship was also proposed based on the experimental test results (in relation to the mechanical properties) in line with American and Indian standards code of practice.

“…In this regard, the working hypothesis of the study is the development of the most cost-effective formulation with the maximum use of cheap raw materials, which can primarily be obtained from industrial and other types of waste used for manufacturing such products. One of the most demanded is the use of the production waste of the fuel and energy complex, i.e., production waste obtained during the operation of industrial and agro-industrial facilities, which is discussed in [49][50][51][52][53][54][55][56].…”

Nano-Modified Vibrocentrifuged Concrete with Granulated Blast Slag: The Relationship between Mechanical Properties and Micro-Structural Analysis

Currently, in civil engineering, the relevant direction is to minimize the cost of the manufacture of the hollow structures of annular sections, as well as their construction and installation efficiency. To optimize the costs associated with building products and structures, it is proposed to apply the technology of vibrocentrifugation, to reconsider and comprehensively approach the raw materials for the manufacture of such products and structures. The purpose of this study is a theoretical substantiation and experimental verification with analytical numerical confirmation of the possibility of creating improved variotropic structures of vibrocentrifuged concrete nano-modified with ground granulated blast-furnace slag. The study used the methods of electron microscopy, laser granulometry, and X-ray diffraction. Slag activation was carried out in a planetary ball mill; samples were prepared on a special installation developed by the authors—a vibrocentrifuge. The optimal and effective prescription–technological factors were experimentally derived and confirmed at the microlevel using structural analysis. The mathematical dependencies among the composition, macrostructure, microstructure, and final properties of vibrocentrifuged concrete nano-modified by slag are determined. Empirical relationships were identified to express the variation of some mechanical parameters and identify the relationship between them and the composition of the mixture. The optimal dosage of slag was determined, which is 40%. Increases in strength indicators ranged from 16% to 27, density—3%.
