Summary: Incorporating rice husk ash led to an improvement in compressive strength of high-calcium fly ash geopolymer modified with borax, while using borax instead of sodium silicate resulted in decreased strength. The decrease in strength when using borax was attributed to the increase in crystalline nature of reaction products caused by lower Si/Al ratios in the gel phases formed.

Summary: Peat is a geotechnically problematic material due to its high organic content, but can be stabilized using nontraditional materials like rice husk ash-based geopolymer. By adjusting the combination of binder content, concentration, and A/B ratio, the geopolymer can significantly increase the compressive strength of treated peat, filling pore spaces with cementitious products like zeolite.

Summary: The utilization of rice husk ash in development of geopolymer binders in India can help alleviate environmental problems. This study focuses on developing GEOPAV blocks using brick kiln rice husk ash (BKRHA), which showed improvements in split tensile strength and flexural strength, as well as enhanced resistance to acid and frost attack compared to commercially available paver blocks. The addition of BKRHA contributes towards forming a dense geopolymer matrix with high amounts of amorphous silica, leading to improved performance of GEOPAV blocks.

Summary: This study investigated the feasibility of using ceramic dust and rice husk ash instead of traditional blast furnace slag in the production of geopolymers. The results showed that the use of rice husk ash had a negative impact on flowability and water absorption rates, while the use of ceramic dust led to geopolymers with higher density and porosity.

Summary: Utilizing industrial by-products in concrete can help reduce the depletion of raw materials, but it may affect the concrete's performance. This study focused on geopolymer concrete developed from fly ash and fine rice husk ash, with partial OPC substitution. Various properties were investigated to assess the strength and durability of the concrete. The results showed that 20% OPC substitution improved workability, while 15% OPC substitution achieved the highest compressive strength and durability performance.

Summary: This study investigated the recycling of agro-industrial waste materials such as sugarcane bagasse ash and rice husk ash as partial replacements for cement in concrete production. It was found that the strength performance of concrete decreased when using these materials individually or in combination, but they could still be suitable for structural applications at certain replacement levels.

Summary: The effect of partial replacement of cement by unground residual rice husk ash (RHA) on the workability and compressive strength of concrete was investigated. An optimal replacement ratio model and a compressive strength prediction model were established. The results showed that the addition of RHA had a negative effect on the workability of concrete, while the mechanical properties were optimal when the content of RHA was 20%.

Summary: Over the years, the cost and environmental issues with traditional building materials have become a concern due to increasing human population. This study investigates the development of a sustainable composite using quarry dust and rice husk ash, as a partial replacement for river sand and cement respectively. The results show that the compressive strength of the non-conventional composite samples increased with curing age, while the bulk density was lower compared to the conventional composite samples. The study suggests that quarry dust and rice husk ash can be used to develop sustainable building materials.

Summary: This study focuses on the preparation and characterization of alkali-activated slag based geopolymer foamed material (GFM) with the addition of rice husk ash (RHA). The inclusion of RHA improves thermal stability, thermal insulation, compressive strength, and specific compressive strength of GFM, leading to lightweight high-strength developments. Furthermore, replacing GGBS with RHA effectively mitigates strength degradation, reduces weight loss, and enhances volumetric stability during thermal exposure.

Summary: This study analyzes the characteristics of process parameters in three lean gas ethane recovery processes and establishes a prediction and multiobjective optimization model for ethane recovery and system energy consumption. A new method for comparing ethane recovery processes for lean gas is proposed, and the addition of extra coolers improves the ethane recovery. The support vector regression model based on grey wolf optimization demonstrates the highest prediction accuracy, and the multiobjective multiverse optimization algorithm shows the best optimization performance and diversity in the solutions.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.

Summary: This study uses survey data from the Loess Plateau in China to evaluate the impact of social interaction on the adoption of soil and water conservation (SWC) technology by farmers. The study finds that social interaction increases the likelihood of farmers adopting SWC, and internet use moderates this effect. The positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies.
