Experimental Effect of Cassava Starch and Rice Husk Ash on Physical and Mechanical Properties of Concrete

Analysing the Effect of Cassava Flour as a Mixture on the Physical, Mechanical, and Durability Properties of High-Strength Concrete

“…Age-related gains in strength have been seen, for instance, by Okafor (2010) [36]. Similar findings were found by Ikoko et al, 2021 [41], Xavier (2020) [59], Kone et al (2022) [34], and Oluwabusayo Oni et al, (2020) [25]. Since it can make concrete stronger when it's pressed, cassava flour could be thought of as a green material additive.…”

“…Therefore, some researchers have focused on using naturally occurring admixtures to improve the hardened and fresh properties of concrete, which are widely accessible, economical, eco-friendly, and may be processed locally to reduce dependence on imported chemical admixtures. Regional materials that have been investigated as concrete admixtures include corn starch [27], sorghum flour [28], Arabic Karoo gum [29,30], okra extract and cypress tree [37,38], and cassava starch [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Cassava is a woody tree that is grown in tropical and sub-tropical regions because of its roots, which contain a high percentage of starch.…”

“…According to these results, cassava starch positively affected the compressive strength and gave more stiffness in the form of cohesion and stability, resulting in reduced shrinkage in concrete. Other studies were conducted by Kone et al (2022) [34], who investigated the effect of cassava starch and rice husk ash on the physical and mechanical properties of concrete containing 2% cassava starch added by the weight of cement and 20% rice husk ash replacement of cement. The RHA was burnt at temperatures of 650 °C, while cassava flour was used to prepare the starch.…”

Investigation on microstructural and compressive strength characteristics of a novel bio-admixture comprising Cassava Starch-Xanthan gum with cement mortar for building application

“…Polymers which assist in the modification of rheological characteristics during the casting process are now essential components of several advanced concrete systems for that cement pastes with polysaccharides, acacia gum and cassava has been investigated [18]. Recently, an investigation was performed to determine to utilize rice husk ash in place of some of the cement and cassava starch (CS) as a natural additive in the creation of fresh and hardened concrete [19]. Researchers also investigated the effects of carrot extract on the properties of cement-based materials at both the macro and micro levels using a variety of detection techniques.…”

Employing spatial, hybrid and amplitude roughness parameters for unveiling the surface roughness features of mineral and organic admixtures

“…It should be mentioned that the method of preparing the materials manifests surface roughness character of such materials [ 9 ]. It must be mentioned about a commonly known characterisation process of surface morphology, texture and roughness of mineral admixtures using scanning electron microscopy (SEM) reported in literature [ [13] , [14] , [15] , [16] , [19] , [20] , [21] , [22] ], which is similar to atomic force microscope (AFM), but leaves the quantitative surface roughness parameters out of sight. Examining the details of mineral admixtures using SEM has turned out to be limited for measurements of surface roughness parameters since the method is usually based on qualitative assessment [ 23 ].…”
