This paper mainly studies the substitution effect of the superfine powder on cement after the use of superfine powder in concrete The experiment shows that the superfine phosphor slag powder can significantly improve the performance of C60 high performance concrete and has an important role in the retention value of 1h slump The incorporation of
Aggregates make up 85% of cement based products mass [1] [15] [16] and these materials are derived from natural rocks and sand submitted to low industrial to the Brazilian National Association of Aggregate Producers [17] in 2014 the aggregates production sector had a demand of 740 million tons of gravel and sand
Alkali activated slag AAS attracted wide attention in low carbon cementitious materials In this study superfine slag was activated by sodium carbonate SC and marble powder MP was also used
A composite mineral admixture was prepared by steel slag and superfine blast furnace slag The influence of superfine blast furnace slag content of the composite mixture on the mortar and concrete was investigated The results show that the composite mineral admixture may decrease the strength of concrete at the early age but improve the strength development

Alkali activated slag AAS attracted wide attention in low carbon cementitious materials In this study superfine slag was activated by sodium carbonate SC and marble powder MP was also used The effect of MP on SC activated slag binders were investigated in terms of fluidity compressive strength hydration heat and microstructure analysis
The results show that superfine blast furnace slag powder can be effectively used in cement with high contents The strength of cement mortar with 70% superfine blast furnace slag powder still can meet the requirements of Portland cement P•O 32·5 Meanwhile superfine blast furnace slag powder can improve fluidity of cement based materials
It is evident that SS 2 SS 3 and SS 4 superfine steel slag have much less coarse particles larger than 50 μm in diameter and more fine particles smaller than 1 μm in diameter than that of SS 1 ordinary steel slag powder Therefore superfine steel slag is more likely to induce high hydration activity than ordinary steel slag powder
Steel slag powder was used widely in cement concrete industry and road construction to improve the workability and durability of cement concrete construction materials Cui et al 2016;Guo and
The influence of the replacement ratio fineness and age of superfine slag powder on the properties of cement paste was investigated by tests with XRD
India Small Superfine Slag Powder Making Line works on aluminum metallic bronze copper ore molybdenum also nonmetallic stones like bentonite limestone quartzGulbarga slag powder production line processing rock The production process of the original slag is as follows 1 Pretreat the slag and the dried slag in the storage bin enters the
Slag as shown in Fig 1 is the 16th ingredient of high performance concrete production [22] called supplementary cementitious materials SCM [23] that can enhance the strength and durability of concrete [2] The highly fine slag powder with a surface area of 400 600 m 2 /kg and a bulk density of 1200 kg/m 3 can be mixed with free lime to replace 40% to 65%
When 20% cement replaced by the superfine phosphoric slag the compressive strength of concrete see Table 3 No 2 decreases % in 7 day increases % in 28 day No 1 With the superfine phosphoric slag and superplasticizer the compressive strength of concrete No 4 decreases % in 7 day increases % in 28 day No 3 The
