“…Pore obstruction and decreased capillary porosity are likely to be blamed for the decrease in water depth that may be observed in Substance S2. The results of the durability tests that were carried out in this research are supported by this outcome (6) . There does not appear to be any noticeable difference between S2 and S1 regarding water absorption.…”

“…Examining the impact of SCM on the fresh and hardened properties and the durability of concrete has been extensively explored and advocated (4) . The researchers have admitted to utilizing granulated blast furnace slag (GBFS) and fly ash (FA) to improve the freshness and hardness of concrete (2)(3)(4)(5)(6)(7)(8) . When OPC, GBFS, and FA are mixed, the calcium-silicate parts in OPC clinker, such as C 3 S and C 2 S, start to dissolve.…”

Background: Thermal cracking, delayed ettringite production and low tensile strength are three significant problems for high-strength concrete. Objectives: The current experimental study aims to determine the durability characteristics of concrete for application in pavements. To test how well the M40 grade of concrete absorbed chloride and water, the amounts of Supplementary Cementitious Materials (SCM) like Granulated Blast-Furnace Slag (GBFS) and fixed amounts of Fly Ash (FA) and Macro Synthetic Fiber (MSF) were optimized. Methods: One sample (S1) was made entirely of Ordinary Portland Cement (OPC) and five samples (S2, S3, S4, S5, and S6) made simply of SCMs, in which OPC was substituted with 20% FA+20% GBFS+1.5% MSF, 20% FA+25% GBFS+1.5% MSF, 20% FA+30% GBFS+1.5% MSF, 20% FA+35% GBFS+1.5% MSF, and 20% FA+40% GBFS+1.5% MSF, respectively, were cast in standard blocks with a volume of one cubic meter for this purpose. Field Emission Scanning Electron Microscopy (FESEM), Fourier-Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD) investigations are used to examine the number of hydration products created at 28 days, which differ for different percentages of SCMs. Findings: Furthermore, 501, 520, 535, 565, and 590 coulombs are the measured Rapid Chloride Permeability Test (RCPT) values for the S2 to S6 samples. Similarly, the S1 sample is projected to have more than 2600 coulombs, showing a better endurance of samples based on SCMs. The microstructural characterization findings (i.e., XRD, FTIR and FESEM) suggested that GBFS and FA are promising SCMs for enhancing the strength and durability properties of the mix. Novelty and applications: This study validates the viability of using GBFS, FA, and MSF in pavement applications, yielding noteworthy environmental advantages and lowering dependency on OPC.

Sustainable building technology is a new approach adopted in built environment, which is focused on significantly reducing impact of the construction industry on the environment. Moreover, the world is largely driving development of sustainable and smart products to mitigate global pollution issues. In this study, assessment of the impacts of using alternative constituents such as crumb rubber, coconut shell, recycled aggregate, GGBS, human hair, banana fiber, industrial sludge, saw dust, rice husk, wood waste, textile, copper slag, textile, glass powder, plastic etc., on concrete strength development using case studies has been performed. The paper explores the research work carried out towards sustainable approach in replacement of basic composition of concrete. It focuses on various waste materials used as a substitute options in concrete and characteristic strength development along with potential challenges. Leading researches relating to sustainable materials were also explored. The results show that the alternative aggregates, mostly with minimally usage of about 20% increased the compressive strength properties of concrete. Usage of fibres to about increased the flexural property of concrete and the replacement of waste sludge didn't show appreciable increased of compressive strength.

Now a day, the utilization of self-compacting concrete (SCC) has become popular in creating RC structures. Apart from self-compaction, SCC has got many advantages such as excellent flow ability, filling ability, smooth finish of surface, ease of work etc. The use of waste material in concrete is the area of having scope for researchers for many years. Use of waste material reduces the consumption of cement by construction sector. In this present experimental work, dolomite powder is used as fractional replacement material for cement. The cement in the SCC is replaced by dolomite at fractions of 10%, 20%, 30%, 40%, 50%, 60%, and 70%. Fly ash is also added to the mix at constant fraction of 18% of the cement. The strength of SCC is assessed by performing compression test, splitting tension test and bending test. The test results showed that the use of dolomite powder in SCC is advantageous up to 20% replacement fraction. It is also observed that the strength of DC40 mix (i.e the mix having Dolomite at 40% of cement) is almost equal to the strength of normal SCC. Even at 70% replacement level, the strength of SCC having dolomite achieved is 25 MPa. SEM images are analyzed to identify the spread of hydrated products.
