The grinding process improves the activity of RCP to a certain extent, while a long grinding time leads to fusion and aggregation between powders. Investigation on CO 2 emission demonstrates that carbon emission from cement production accounts for the largest proportion, 80~95%, in the total emission from mortar production. Combined with the ...
2010 saw a significant development for HDT when it was incorporated into the clinker grinding process and by 2013 as a recognised grinding aid for slag. HDT nano molecular technology was trademark registered in 2012.
Moreover, the concrete samples containing nano-GO/Al 2 O 3 and nano-Al 2 O 3 are more durable against freeze-thaw cycles than those without nanoparticles. The compressive strength under different freeze-thaw cycles is conducted, and the results are shown in Figure 7 for different contents of Al 2 O 3 and GO/Al 2 O 3 nanoparticles.
In addition, the morphology of the nano-BRHA changed with grinding duration. Finally, the use of nano-BRHA produced porous concrete pavement …
Grinding of micro-silica makes changes in the microstructure of its particles and compressive strength was considerably increased after grinding. The effect of grinding for 5% micro-silica added concrete on compressive strength increased to 14, 30 and 29% for 4, 6 and 8 h duration, respectively. There is a reverse trend for 10% micro-silica ...
admixtures in concrete. Also the use of nano sized mineral admixtures were also studied on self compacting concrete using SiO 2 [15, 16], Fe 2O3[17] and ZnO 2[18,19]. In addition the effects of several types of nano particles on properties of concrete specimens which are cured in different curing media were investigated in several works [19].
