For these mixtures, the water volume fraction (content) was maintained constant and cement was replaced by the limestone or silica powder at a 1:1 ratio on a volume basis, producing variable water-to-powder ratios ( w/p) on a mass basis. Systems varying from 100 % OPC to 5 % OPC:95 % LS were examined. In addition, mixtures with SA were …

The filler effect of limestone, which causes the more even distribution of clinker grains, may disperse the clinker grains, preventing their coagulation during the first hour of hydration. The results indicate that in relation to rheological properties, there might be an underlying issue of compatibility between the cement and limestone. It can ...

Wood putty is denser than wood filler, and it's so pliable you typically have to apply it with a putty knife. Like window glazing or plumber's putty, wood putty is a mixture of plastic and oil-based solvents. Because it doesn't harden like wood filler, wood putty won't shrink or crack, but you can't sand it.

There is nothing messier than a path with pebbles dotted all over it. Of course, pea gravel, for instance, shifts when walked on—and this is part of its character—but it shouldn't become a hassle. To mitigate the mess, lay filler stone between the pavers at a height slightly lower (at least half an inch) than the surface of the paver.
