Influence of wastepaper sludge ash as partial cement replacement on the properties of lightweight foamed concrete

Formulating Eco-Friendly Foamed Mortar by Incorporating Sawdust Ash as a Partial Cement Replacement

“…The decrease in the wet, demolding, and dry densities of FM when SDA is used as a partial replacement for cement may be due to the lower bulk density of SDA compared to cement, as indicated in Table 2. The inclusion of SDA in the FM mix results in a reduction in its overall density, as sand particles possess a greater density compared to SDA [21]. As a result, the utilization of SDA as a replacement for cement results in reductions in the wet, demolding, and dry densities.…”

“…Implementing FM has the capacity to significantly decrease the total weight of a building, hence potentially reducing the risk of damage caused by earthquakes [17][18][19][20]. Furthermore, the implementation of FM significantly reduced the consumption of cement and aggregate materials [21,22]. It has been noted that the cement production process contributes to around 6% of the total global carbon dioxide (CO 2 ) emissions.…”

“…Hence, the application of sawdust continues to provide challenges and poses potential risks to the ecological and environmental systems. Wood sawdust ash was utilized as a pozzolan in concrete as a partial substitute for cement or aggregate in recent experiments [18][19][20][21]. The ideal range for the compressive strength of cement mixed with wood ash, as determined by Sajjad et al [38], was found to be between 10% and 20% by weight of the binder.…”

Enhanced fresh and hardened properties of foamed concrete modified with nano-silica

“…For concrete production, however, to maintain concrete quality, the requirement of mineral admixture is promoted nowadays [ 6 , 7 ]. Compared to conventional construction, there are a lot of advantages, like cost savings, reduction in self-weight, excellent fire resistance, etc., associated with the usage of foamed concrete (FC), which pushes to use it in the global building sector [ [8] , [9] , [10] , [11] , [12] , [13] , [14] ]. Typically, FC is referred to as a porous or cellular lightweight material that is suitable for an extensive variety of applications in construction [ 15 , 16 ].…”
