Summary: This study provides a review on the use and effectiveness of ground-granulated blast-furnace slag (GGBS) as an alternative to cement. The findings indicate that GGBS can improve the mechanical strength of concrete but reduce its flowability. Additionally, concrete containing GGBS cement shows superior durability. The optimum percentage of GGBS is a crucial aspect for achieving better performance.

Summary: The present investigation aims to study the mechanical and durability performances of Fly Ash (FA), Ground Granulated Blast Furnace Slag (GGBS), and Metakaolin (MK) blended Self-compacting Geopolymer concrete (SCGC). The significance of the investigation is to study the application of SCGC composites over conventional cement concrete for infrastructure. The experimental results show that the FA-SCGC, FG-SCGC, and FM-SCGC mixes have better performance against acid and salt solutions.

Summary: The study investigates the use of slag waste as cement replacement in steel fiber reinforced concrete to improve durability in a marine environment. Results show that GGBS incorporation leads to reduced chloride ion penetration depth, lower migration coefficient, and significantly higher service life, indicating effective waste utilization for enhanced durability and service life in construction and building materials.

Summary: This study explores the concrete leaching mechanisms of hydropower structures exposed to river water for 40 years, leading to increased porosity and decreased mechanical properties. Long-term exposure to soft water has caused chemical and mineralogical alterations in some regions of the concrete, with leaching effects localized in areas of highest percolation flows.

Summary: This study examined the properties of pervious concrete made with coarse recycled concrete aggregates (RCA), recycled fine glass (RFG), and ground granulated blast furnace slag (GGBS). Substituting with RCA and RFG decreased slump and density but increased porosity and permeability of the concrete. While RCA replacement had a more noticeable negative effect on compressive strength, RFG replacement was more impactful on splitting tensile and flexural strengths. The inclusion of GGBS enhanced the performance of pervious concrete.

Summary: This study investigates the feasibility of using 20% recycled aggregate and treated wastewater in concrete mixes, and analyzes the impact of their individual and combined effects on concrete subjected to different exposure conditions. The results show that the effect on concrete compressive strength was significant only when 20% RA was used in concrete exposed to TWW.

Summary: The behavior of concrete made with recycled concrete aggregates (RCA) at room temperature has been well studied, but there are still unresolved issues regarding durability and high temperature conditions. This paper evaluates the impact of elevated temperatures on the durability of concrete made with RCA. Three concrete mixes were studied: concrete with natural aggregates (NA, reference), 100% direct replacement (DR) mix (RCA-100-DR), and 100% strength-based replacement (SBR) mix (RCA-100-SBR). The mixes were subjected to temperatures of 200 degrees C and 400 degrees C.

Summary: This article discusses the potential of using graphene as a reinforcing filler in cementitious composite to enhance their functional performance. Graphene has remarkable features such as efficient heat and electrical conductivity, as well as remarkable strength, making it a promising additive for concrete. The two-dimensional nature of graphene allows for a high specific surface area, making it an attractive construction material.

Summary: This paper investigates the influence of curing conditions on the durability of mortar samples consisting of various amounts of ground granulated blast-furnace slag (GGBS), which is used as a substitute for cement to reduce carbon dioxide emissions. Experimental results show that samples cured in standard conditions perform the best, and samples with 45% GGBS content exhibit superior durability properties. A developed numerical model accurately estimates the hydraulic characteristics of mortar samples.

Summary: This study investigates the effects of salt solution on the mechanical behaviors of geopolymer concrete under dry-wet cycles. The results show that the mass of the specimen slightly increases and then gradually decreases with the increase of dry-wet cycles. The stress-strain curve of geopolymer concrete can be divided into three stages, corresponding to elastic deformation, elastic-plastic deformation, and crushing. The compressive strength and elastic modulus of geopolymer concrete decrease with the increase of dry-wet cycles, reflecting the strength loss caused by sulfate erosion. Different salt solutions have significant influence on the properties of geopolymer concrete, with mixed salt solution causing the greatest damage and sulfate solution showing a certain inhibitory effect.
