Crusher fines that result from hard rock feature rough, fractured edges. When packed tightly on the ground, the fines lock into one another, creating a firm, stable surface for walking and driving. If compacted tightly enough and well maintained, it can be smooth for wheelchairs and walkers and act as an alternative to different types of pavers .

Step 3 - Fill Low Areas. Fill low areas with dirt first so that you won't have to use the more expensive crusher rock to raise water-collecting low spots. Install any necessary culverts by digging a trench wider than the culvert pipe. Bury the pipe so that water streaming to that area will flow through the culvert and not over your path.

The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because …

Type of 0/8 mm sand material investigated in D max of 8 mm concrete (mixes 1–7) While keeping the other mix parameters constant, the only variable has been the type of the 0/8 mm sand material in order to evaluate the performance of the washed crushed sand material C-0/8-nw compared to the unwashed feed material C-0/8-u and …

"The quality of natural sand varies more than that of sand produced in an industrial process. Consistent quality is a typical feature of crushed sand. Concrete manufacturers benefit from the use of sand that is of a stable quality, because it allows them to use less cement, typically between 5% and 20% less cement.

Concrete sand is a label that is typically used to describe the coarse washed sand that is a common ingredient in cement and asphalt mixtures. Its grains are larger than those of masonry sand, but a …
