Influence of Alkali Resistant Glass Fiber on the Reduction of Plastic Shrinkage Cracking of Self Compacting Concrete

Fresh and Hardened Properties of Ternary Blended Fast Setting Early Strength Fibre Reinforced Self Compacting Concrete

“…Incorporation of MK in concrete develops its performance by emerging further CSH gel formation by consuming Ca(OH) 2 , formed during the process of cement hydration, and thereby densifying the matrix resulting in reduced porosity [25]. MK develops pozzolanic reactions in fresh state and quickens the hydration reactions of cement [27]. It was demonstrated that higher silica, as present, in MK mends pozzolanic responses of concrete thereby enhancing strength and durability of concrete [32].…”

“…The appropriate mix of SCC can be realized by experimental procedures [4]. Various techniques have been established to study the behaviour of SCC [27]. Hence, every mix design of fibre reinforced SCC needs to be established by a series of trials to achieve various workability factors [46][47][48].…”

“…The consequences of fibre inclusion in the SCC mixes are explored on its mechanical properties such as compressive strength, split tensile strength and flexural strength of fibre reinforced SCC and established that incorporation of fibres into SCC though reduces workability (which can be counteracted through effective use of PCE based chemical admixtures), effectively increases the mechanical properties [26]. The influence of alkali-resistant (AR) glass fibre, as discrete reinforcement, at 0.03%, 0.06% and 0.1% on durability characteristics of concrete was explored and reported that, for all the grades of concrete, incorporation of AR fibres at 0.1%, maximum enhancement in durability characteristics of concrete was achieved [26][27][28]. This contradicts with the outcome of the study [26] stating that 1% AR fibres incorporation improves the durability performance of concrete [28], hence further research may be required to ascertain the effects of AR fibres in SCC.…”

Study on Shrinkage Properties of Repairing Mortar Modified by Basalt Fiber

“…Some researchers found that the shrinkage properties of cement-based materials are significantly improved after the addition of appropriate fibers, such as steel fiber (SF) (Al-musawi et al 2019, Roberti et al 2020 , polypropylene (PP) fiber (Marushchak et al 2022, Ma et al 2022, basalt fiber (BF) (Punurai et al 2018, Zheng et al 2019. Some characters (Saje et al 2013, Ma et al 2017, George and Abin Thomas 2020 of fiber, like length, length-diameter ratio and the dosage of fiber, have great influence on the improvement of shrinkage. In the cement hardening stage, these fibers are evenly distributed in matrix and connected with plenty of the pores in the interior, which inhibit partial shrinkage cracks.…”
