“…Water absorption test was performed based on BS 1881: Part 122 at the age of 28, 90, and 180 days. The goal of this test is assessing the permeability of concrete regarding that results are related to capillary pores of the specimen . Three cylindrical cores with a diameter of 75 mm and height of 150 mm were obtained by drilling from the hardened concrete.…”

The degradation caused by corrosion of rebar in concrete structures is one of the most important issues to attract the attention of researchers focused on concrete durability. Penetration of chloride ions into concrete is one of the factors that can contribute to corrosion of rebar and consequently the strength of concrete structures as well as serviceability reduction. In this study, an experimental model was proposed to predict penetration of chloride ions into cracked concrete by performing non‐destructive tests. Tests were performed after 48‐months exposure of all samples to a harsh marine environment. For studying the influence of load‐induced cracks on the rebar corrosion, cracked and uncracked beams were tested. Results of this study demonstrated that by the increment of the crack width, corrosion of reinforcement increased and as a result, the probability of degradation of reinforced concrete beams increased accordingly. Furthermore, by the increment of crack width, their depth also increased which caused enhancement of crack depth on the rebar and easier access of chloride ions to the rebar.

“…Grout is a construction material with filling ability in narrow spaces, and mostly used in repair and rehabilitation of concrete structures. Considering the wide-ranging applications of grouts, studies have recently been given attention to investigate the effects of various factors on quality and cost of grout [2]. Currently grouts are using in different construction applications, such as to reduce the flow of seepage, fixing reinforcing elements in pre-stressed concrete structures, to fill voids where concrete cannot reach, to fill cracks in massive concrete structures, to strengthen a foundation, rehabilitating defective masonries in historical buildings and so on [3].…”

Generally, grout is a combination of cement, sand, and water (with or without admixtures), which poses low viscosity and high penetrability. Grout is very suitable for anchoring application, jacking of concrete elements, grouting of ducts in prestressing application, application in narrow joints and many more. Nowadays it is used to provide additional strength to load-bearing structures. The grout characteristics includes the flow capacity in narrow space and physicalchemical compatibility with the substrate materials. However, shrinkage, stability, leaching of the grouts, etc. are the main problems of cement grouting. Supplementary cementitious materials (SCMs) such as fly ash, ground granulated blast furnace slag (GGBS), silica fume (SF) etc. can be used as admixtures in cement grout to reduce the problems associated with grout. This paper provides a review on the assessment of the flowability, strength, shrinkage and chemical resistance of the cementitious grouts containing SCMs, and its feasibility in grouting applications. This paper reveals that combination with SCMs in the production of cement-based grouts provides advantages in specific uses in concrete industry.

“…Sanderson (2017) showed that the peak heat and the evolution of heat increased with the rise in GGBS content [20]. Alireza Joshagani (2018) developed high-performance non-shrinking grout (HPNSG) using fly ash, slag, and silica fume [21]. Sha (2018) make mixtures to ensure fluidity, penetrability, and less leaching.…”

This article presents a study of the main properties (consistency, workability, leaching, unsoundness, and mechanical properties) of cement grouts prepared with cement replacement by blast furnace slag (GGBS). Mixtures have been analyzed in the absence of additives and reached high replacement percentages. As shown in the different tests presented, the observed evolution of the resistance and workability of the mixtures makes them very interesting for its application. Different types of cement (CEM-I 42.5 and CEM-I 52.5 R) and different water/binder values (1 and 0.67) are used. The results present opportunities for the steel industry by the intensive valorization of slag waste. The reduction of the use of cement in construction is also one of the key aims of this line of research. Results show improvements in the mechanical response with good fresh state properties for substitution percentages up to 70%. It is verified with leaching analysis that these products have less impact on the environment.
