Construction block made from hempcrete Illustration of hemp concrete carbon emissions and sequestration, with a net emissions balance indicating carbon negativity. Hempcrete or hemplime is biocomposite material, a mixture of hemp hurds and lime, [1] sand, or pozzolans, which is used as a material for construction and insulation. [2]
The structural properties of this material are similar to those of Portland cement-based mortars: it has an elastic modulus of 293.9 MPa, and a tensile strength of 3.6 MPa (the minimum required value for Portland-cement based concrete is approximately 3.5 MPa); [2] however it has a fracture energy of 170 N, which is much less than most standard ...
Many types of stone are stronger than concrete in compression. Stone uses much less energy to produce, and hence its production emits less carbon dioxide than either brick or concrete. Stone is widely considered aesthetically pleasing, while concrete is often painted or clad.

Limestone has numerous uses: as a chemical feedstock for the production of lime used for cement (an essential component of concrete ), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paint, as a soil conditioner , and as a popular decorative ...
PVC roofing is a Thermoplastic system, meaning that it is heat-welded at the seams forming a permanent, watertight bond that is typically stronger than the membrane itself. PVC resin is modified with plasticizers and UV stabilizers, and reinforced with fiberglass non-woven mats or polyester woven scrims, for use as a flexible roofing membrane.
