“…At present, the mixture ratio design of CPB refers to the relevant theory of concrete. Mitchell and Wong established the strength model by a large quantity of tests which show that the uniaxial compressive strength relates to the porosity, water cement ratio, and binder content [10][11][12][13]. Swan used "cementing agent coefficient" to estimate the uniaxial compressive strength which is related to the cementing agent content [14][15][16].…”

The relations among the uniaxial compressive strength of cemented paste backfill (CPB) with solid phase mass fraction, cement sand ratio, and curing age were studied. The UCS of CPB samples increased exponentially with the increase of solid phase mass fraction and curing age but increased linearly with the increase of cement sand ratio. The results of X-ray diffraction (XRD) and scanning electron microscope (SEM) showed that the strength was determined by the amount of ettringite and C-S-H gelling. With the increase of ettringite and C-S-H gelling, the strength became larger. The triaxial compression test was conducted by selecting four kinds of CPB samples. The results showed that, with the increase of confining pressure, peak and residual strength became larger, but the elastic modulus decreased. When the ratio of confining pressure and uniaxial strength is about 1 : 2, the CPB samples show significant ductility characteristics and the ratio of residual strength and peak strength increased obviously.

“…Contradictory, [68] concluded that the addition of the cenosphere may decrease the strength so that it can be stabilized by the addition of silica fume. The property of nano-silica is to improve the interfacial transition zone in concrete, thereby obtaining an earlyage strength and attains a high compressive strength [69][70][71][72] stated that a slight decrease in strength of the mortar even at low density and low thermal conductivity of the cenosphere. 65] stated that strength loss in mortar can be strengthened by improving the interfacial property by using the cenosphere.…”

The secondary form of waste is the major outcome of the various industries. Likewise, Cenosphere and Ground Granulateds Blast Furnace Slag (GGBS) are the waste material obtained from thermal power plants and the steel industry. This waste requires a large land area for disposal. In such cases, these can be used in the construction field. This paper investigated the lightweight wall panel made with cenosphere and GGBS as a replacement for cementitious material. Cenosphere was replaced at 5%, 10%, 15%, 20%, 25% and 30% respectively by weight of cement and GGBS was at 15% constant replacement of cement. The properties of wall panels such as compressive strength, flexural strength, and water absorption have been studied. The flexural behavior was carried out by inhibition of fiber into the matrix. The samples were tested at 7, 14, and 28 days respectively. The SEM analysis of the cenosphere has been carried out. The results infer an increase in the percentage of cenosphere does not impart strength to the mix. Therefore, 15% of constant replacement of GGBS to the mass of cement stabilize the strength which was lost due to the addition of the cenosphere. On an overall view, it was recommended that the strength loss of mixture due to the addition of the cenosphere can be alleviated by GGBS and nevertheless a secure value of strength can be gained.

“…Previously, many investigations have been done by researchers to develop cost-effective concrete by blending industry by-products with cement [32][33][34]. Hence this study is envisaged to develop a new ecosustainable composite by using cenosphere as an alternative material for cement [35][36][37][38][39].…”

“…In a cement mantle, sufficient water should be incorporated to seal the voids present among solid particles [47][48][49][50][51][52][53][54][55]. If the voids are unfilled, the air may entrain into the concrete and that may result in strength reduction [56][57][58][59][60][61]. Hence in this research, the cenosphere content is varied for different W/C ratios to assess the mechanical and rheological properties.…”

Cenosphere is a captivating material in the realm of cementitious materials. Its unique properties, such as being superfine, spherical, and hollow, make it a suitable additive in concrete. Fine cenosphere particles can efficiently bridge the gap among the cement particles. This increases the density and reduces porosity, thereby enhancing the performance of the concrete. The experimental results suggest that incorporating cenosphere up to 15% can lead to notable improvements in the properties of the concrete. This optimal content ensures the enhancements without detriment to the other significant characteristics of concrete. In the present scenario, cenospheres offer a sustainable solution for enlightening the characteristics of cement paste and reducing the environmental footprint of waste accumulation.
