Fine limestone accelerates early-age hydration, resulting in comparable or better 1-day compressive strengths, and increased calcium hydroxide (CH) contents as compared to pure cement pastes. The incorporation of metakaolin in conjunction with limestone powder alters the heat release (i.e., kinetic) response significantly.
It makes your pathway firm, but not concrete, still natural. Stabilizing natural materials like decomposed granite, crushed granite, crushed stone, limestone, or crushed rock (gravel), means your natural pathway can now withstand traffic, remain accessible, and resist the effects of weather.

Sandstone is formally defined strictly by particle size, but rocks made of carbonate minerals don''t qualify as sandstone. Carbonate rocks are called limestone and given a whole separate classifiion, so sandstone really signifies a silie-rich rock. (A medium-grained clastic carbonate rock, or "limestone sandstone," is called calcarenite.)
