“…With the goal of reducing the percentage of clinker in blended Portland cements, there has been intensive research to study the interaction of superplasticizers with limestone [92][93][94][95][96]70], fly ash [93,[97][98][99][100], silica fume [101,95,102,103] slag [104,78,105], nanosilica [106,100,[107][108][109], and metakaolin [105]. Recently, Burgos-Montes et al [110] studied the compatibility between superplasticizer admixtures and cements with mineral additions.…”

“…Study showed that the strength of grout reduced slightly with increasing replacement level from 10 to 30% for pumice and fly ash incorporated specimens [2]. Some studies reported that fly ash and pumice mixed specimens experience lower strength at higher replacement ratios compared to other pozzolans [2,7]. The slag mixtures exhibited higher strength than those of control mix due to high pozzolanic reactivity the slag [2].…”

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.

“…FM is defined as an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves and dividing the sum by 100. The sieve sizes are 150 μ m, 300 μ m, 600 μ m, 1.18 19.0 mm, 38.1 mm, and larger increasing in the ratio of 2:1. The same value of FM may be obtained from several different particle size distributions.…”

A parametric experimental study has been conducted to investigate the effect of polypropylene fiber on the workability and fracture properties of highperformance concrete (HPC) composites containing fly ash and silica fume, with the five fiber volume fractions (0.04 % , 0.06 % , 0.08 % , 0.1 % , and 0.12 % ) used. The results indicate that the addition of polypropylene fiber decreases the workability of the HPC composites containing fly ash and silica fume. With the increase in the fiber volume fraction, both of the slump and the slump flow decrease gradually. Furthermore, the addition of polypropylene fiber has greatly improved the fracture parameters of concrete composite containing 15 % fly ash and 6 % silica fume, such as fracture toughness, fracture energy, effective crack length, maximum midspan deflection, the critical crack opening displacement, and the maximum crack opening displacement of the three-point bending beam specimens. When the fiber volume fraction increases from 0 % to 0.12 % , the fracture parameters increase gradually. The variation rules of the fracture parameters indicate that the capability of the polypropylene fiber to resist the crack propagation of the concrete composite containing 15 % fly ash and 6 % silica fume is becoming stronger and stronger with the increase in fiber volume fraction with the fiber volume fraction not above 0.12 % .
