Investigating crumb rubber-modified geopolymer composites derived from steel slag for enhanced thermal performance Ashwin Narendra Raut, Musa Adamu, Ranjit J. Singh, Yasser E. Ibrahim, Anant Lal Murmu, Omar Shabbir Ahmed, Supriya Janga Engineering Science and Technology an International Journal, 2024 Thermal performance of building materials is often improved by introducing air voids through foaming. However, this typically results in a reduction in compressive strength. To address this issue, an experimental study was conducted to develop thermally efficient geopolymer blocks using three grades of crumb rubber (CR), without compromising compressive strength. Tests such as compressive strength, tensile strength, thermal conductivity, water absorption, and porosity were carried out to assess the performance of these blocks in comparison to conventional geopolymer blocks. The CR-incorporated geopolymer blocks demonstrated low thermal conductivity, ranging from 0.63 to 0.43 W/mK, along with a reduced environmental impact and carbon footprint. Importantly, they exhibited high compressive strength, ranging from 25 to 52 MPa, which exceeds the required strength for first-class bricks (12 MPa). A computational conjugate heat transfer analysis was also carried out to evaluate the strength of heat transferred through the solid media to the internal fluid media. It contributes to the advancement of environmentally conscious building materials, emphasizing the potential benefits of crumb rubber-incorporated geopolymer composites as a novel material for building construction purpose.
Effects of agro-industrial by-products as alumina-silicate source on the mechanical and thermal properties of fly ash based-alkali activated binder Ashwin Narendra Raut, Musa Adamu, Veerendrakumar C. Khed, Anant Lal Murmu, Yasser E. Ibrahim Case Studies in Construction Materials, 2023 The construction industry has a potential to incorporate various agro-industrial waste for development of sustainable construction materials which will eventually results in a cleaner and healthy environment. This research emphasizes on incorporation of agro-industrial wastes such as Rice husk ash (RHA), fly ash (FA), copper slag (CS), bottom ash (BA) and glass powder (GP) to develop ecofriendly alkali-activated blocks. The research studies the effect of blending alumina-silica rich agro-industrial byproduct with fly ash and the influence of resulting oxide ratios on the thermal, mechanical and physical properties of the proposed binder. The experimental study indicates that the combination of CS with FA resulted in the highest strength of 63 MPa among all the combinations. However, the NaOH molar ratio also plays a crucial role in performance of alkali activated block as all the mixes having 12 M NaOH resulted in higher mechanical performance. The findings suggest that the raw materials, curing temperature and NaOH concentration also contribute towards strength development apart from the oxide ratios like Si/Al, Na/Al and Na/Si. Finally, a comparative performance analysis amongst the agro-industrial waste (used in current study) as an ingredient to develop alkali activated binder was provided.
Physico-Mechanical and thermal behavior of prolong heat Cured geopolymer blocks Ashwin Narendra Raut, Anant Lal Murmu, Thamer Alomayri Construction and Building Materials, 2023 Geopolymer has played an important role in the development of environment friendly building material using waste from various industries, agriculture and municipal waste. Most of the waste obtained from various industries are pozzolanic in nature or can be made reactive upon processing. Thus, are easy to incorporate in the mix design to achieve desired physical and mechanical properties. However, in practical scenario the total cost of the building materials is controlled by incorporating non-reactive materials as fillers. Considering this, an experimental investigation is carried out to develop with an objective to develop thermally efficient geopolymer block containing a fixed amount of crusher dust as filler and fly ash as the primary precursor and either rice husk ash or bottom ash as partial replacement of fly ash (i.e., 20, 30 and 40 % of fly ash). A combination of sodium silicate and sodium hydroxide mixed in the ratio of 2.5 was used as the alkaline solution and are cured at a constant temperature of 60 °C. The obtained results show that the developed geopolymer has lower thermal conductivity as compared to the traditional bricks and has lower water absorption and porosity values. The compressive and flexural strength are found to be greater than the strength requirement of first-class bricks.
