Any leading home improvement store should supply it. You can give the measurements of your walkway to the sales person, and he'll give you an idea of how much gravel you'll need.
Mesoscale model for thermal conductivity of concrete
By using the measured thermal conductivity in a dry state (1.42 W m −1 K −1) and the porosity (19.74%) of the CM1 cement mortar specimen, thermal conductivity of solid phase of cement mortar in a dry state was obtained by Eq. (8), i.e., λcs = 1.931 W m −1 K −1. In this way, the porosity of corresponding cement mortar can be determined ...

Flamed Finish & Thermal Stone | Flamed Granite, Bluestone, …
First the basics. This technique works to peel away the layers of stone and reveal a new beauty lying beneath. The process is often referred to as a "flamed" or "thermal" finish and can be best described as creating a textured look. While the process can only be applied to stones like granite that have minerals with varying expansions ...
Crushed Granite vs Decomposed Granite: Pros & Cons
Crushed granite is typically limited to grays from light gray to black. It is more limited in colors than decomposed granite. When creating a stable path, crushed granite will compact and make a harder, more stable surface. Compared to decomposed granite and materials, like pea gravel, crushed granite can be harder on the feet due to its rough ...

How to Build a Decomposed Granite Patio | Wild Bloom
Spread and compact the DG in even layers. Once you have the decomposed granite, you'll spread it over the patio area in lifts. Lifts are simply incremental layers that allow you to compact only a small thickness at a time. We recommend laying down and compacting your DG in lifts of 1.5-2" at a time until you have your full thickness.
Thermal Expansion and Contraction of Slabs on Grade
A. A general value for concrete's coefficient of thermal expansion is about 5.5 millionths/° F. If an unrestrained, 100-foot-long slab on grade was exposed to a 100° F temperature drop throughout its cross-section, it would contract about .66 inch (100 feet x 12 inches/foot x 100° F x .0000055). Since the slab is restrained by friction ...
