“…According to Lee et al [ 17 ], the compressive strengths of specimens with silica fume tended to increase with the increase of the replacement amount and curing age due to a pozzolanic reaction [ 17 ]. The results from Lee et al [ 17 ], demonstrate that the addition of silica fume in cement-based composites resulted in a higher compressive strength, a lower absorption, a lower critical pore size, a lower chloride diffusion coefficient, and a lower corrosion rate [ 17 ]. This agrees with Neville [ 14 ], who noted that the pattern of the relation between compressive strength and the water/cement material ratio is the same for concretes with and without SF but, at the same ratio, concrete with SF has a higher strength.…”

Semi-flexible pavement surfacing is a composite pavement that utilizes the porous pavement structure of the flexible bituminous pavement, which is subsequently grouted with appropriate cementitious materials. This study aims to investigate the compressive strength, flexural strength, and workability performance of cementitious grout. The grout mixtures are designed to achieve high strength and maintain flow properties in order to allow the cement slurries to infiltrate easily through unfilled compacted skeletons. A paired-sample t-test was carried out to find out whether water/cement ratio, SP percentages, and use of silica fume influence the cementitious grout performance. The findings showed that the replacement of 5% silica fume with an adequate amount of superplasticizer and water/cement ratio was beneficial in improving the properties of the cementitious grout.

“…The designed direct tensile testing method is a relatively new test that is a modified version of those in previous studies [18,19] as shown in Figure 1. Two lengths of rebar (#6) were placed along the longitudinal axis of the ψ150 mm × 300 mm cylindrical specimen.…”

This study focuses on the effect of the amount of silica fume addition and volume fraction of steel fiber on the engineering properties of cementitious materials. Test variables include dosage of silica fume (5% and 10%), water/cement ratio (0.35 and 0.55) and steel fiber dosage (0.5%, 1.0% and 2.0%). The experimental results included: compressive strength, direct tensile strength, splitting tensile strength, surface abrasion and drop-weight test, which were collected to carry out the analysis of variance to realize the relevancy and significance between material parameters and those mechanical properties. Test results illustrate that the splitting tensile strength, direct tensile strength, strain capacity and ability of crack-arresting increase with increasing steel fiber and silica fume dosages, as well as the optimum mixture of the fiber cementitious materials is 5% replacement silica fume and 2% fiber dosage. In addition, the Pearson correlation coefficient was conducted to evaluate the influence of the material variables and corresponds to the experiment result.

“…The filler effect has two causes, the nucleation effect and packing effect, which depend significantly on the fineness of material. The nucleation effect arises when the small particles are dispersed in the blended cement paste and enhance the cement hydrate while the packing effect occurs when small particles fill the voids of the paste [16,18,27,28]. Therefore, the blended cement paste containing biomass ash with high fineness was more homogeneous and denser, which increased the compressive strength of the paste.…”

“…The percentage compressive strength of paste due to the filler effect tended to increase with the amount of cement replacement and was approximately 2.2-5.1% of the strength of the OPC paste because the small particles dispersed into the blended cement paste and accelerated the hydration reaction. In addition, the packing effect occurred as the small particles filled the voids of the paste [16,18,27,28]. Therefore, the paste was more homogeneous and denser, which resulted in the increased compressive strength of the paste.…”
