When leveraged as a biofuel during hemp ash production, power is generated and metric tonnes of biomass can be diverted from landfills and used as a supplementary cementitious material
. Current estimates indicate close to a billion kilograms of biomass being harvested annually by the marijuana and hemp industry.
High volume fly ash (HVFA) concrete has fly ash content more than 50% of the cementitious material
. Malhotra and Mehta  proposed the definition of HVFA concrete based on the possibility of making high performance concrete using higher volume of good quality fly ash as cement replacement.

An SC-145 mortar consistometer (purchased from Beijing Zhongke Luda Instrument Co., Ltd.; Figure 3) was used to determine the consistencies of the produced cementitious materials
. First, each prepared cementitious material
was placed inside a container.
For the dredged sludge with high organic matter content, the major objective of this study was mainly to use cement and alkali-activated cementitious material
(fly ash, slag, and phosphogypsum) to solidify dredged sludge as a roadbed material.
The mechanistic role of this type of reinforcement has been modeled analytically in  and it comprises the mere addition of effective reinforcement contribution to tensile resistance, [[rho].sub.CNT] x [f.sub.CNT] in the otherwise plain cementitious material
cross section ([[rho].sub.CNT] and [f.sub.CNT] are the effective area ratio and average stress intensity in the CNT network in the direction of tensile load).
Parcel of examination work were done utilizing supplementary cementitious material
as fly fiery remains and more over interest was expanding step by step for fly powder, so elective cementitious waste materials may required to beat this.
"Today, concrete or cementitious-based PFP materials are widely used in the hydrocarbon process and related industries to manage risks associated with pool fires," he explains, "Installation of lightweight cementitious material
often includes welded or galvanised steel mesh systems, all of which add to cost and installation time whilst extending the shutdown period.
Hence because of its particle size, Metakaolin probably require a lesser HRWRA than other cementitious material
like silica fume to achieve the same measurement of slump flow .
The current design of semi-flexible pavement is the imported cementitious material
and modified polymer bitumen.
