The use of biomass as a renewable energy source as well as by using it as a new construction material has attracted global attention over the decades. While works had been conducted on deploying biochar for road construction, there is an emerging trend of using biochar as concrete admixture. In comparison, using biochar in this way will reduce more greenhouse gas emissions than if carbon is captured and sequestered through mineralization and deployment in construction. The use of biochar containing construction materials to capture and then lock atmospheric carbon dioxide in buildings and structures can potentially reduce greenhouse gas emissions by an additional 25%. The results from this project are indicative of a promising future for biochar bricks as a building material. Based on the above results it concludes that biochar bricks would make good veneer because it will easily manipulate shape and surface during molding and are very good insulators, have more compressive strength, and are quite light compared to classic bricks.
The soils contaminated with various organic and inorganic contaminants proceed to the degradation of urban and arable lands throughout the world. The presence of toxic elements may pose a considerable health risk to humans, animals, flora & fauna and other ecological systems. This study investigates the soil contaminated by the carpet industry waste (sludge) and the human non-carcinogenic health risk through the ingestion pathway. A comparative study has also been observed to simulate the field conditions. A typical virgin soil of the region has been selected and mixed with the different proportions of sludge (5%, 15%, 25% & 50%) with respect to the dry weight of soil and the human noncarcinogenic health risk has been evaluated. This research observed that in case of child the Average Daily Exposure (ADE) is very high and the Total Chronic Hazard Index (THI) for all the soil-sludge mixes is more than 10. The THI of industrial sludge is more than the soil-sludge mixed samples with the magnitude of 20.2 and 10.32 in the aspects of child and adult respectively.
Rotational and vertical parts of ground movement are quite often overlooked in plan or in the appraisal of structures in spite of the way that vertical movement can be twice as much as the even movement and may surpass 2g level, and rotational excitation may arrive at barely any degrees in the closeness of deficiency crack. Coupling of various parts of ground excitation may essentially enhance the seismic interest by presenting extra horizontal powers and upgraded force deflection impacts. In this paper, an overseeing condition of movement is hypothesized to figure the reaction of a Single-Degree-of-Freedom Linear Oscillator (SDOF) under a multi-part excitation. The extended condition incorporates auxiliary force deflection parts related with the joined effects of tilt and vertical excitations notwithstanding the inertial compelling terms because of the precise and translational increasing speeds.
Lithomargic soil, known locally as Shedi soil, is typically found below the lateritic soil at a shallow depths, destabilizes the pavements developed on the embankment or subgrade, as they do not have the required shear strength. Deformation of the soft subgrade soil is frequently troublesome during the building of flexible pavements as well as in the postconstruction stage, resulting in increased road operation and maintenance cost. Several studies have investigated the influence of lithomargic soil on contact erosion failure at the boundary between coarse granular material and surface material due to vertical changes in water level. Therefore, before it can be used as a road material, it is necessary to improve the engineering properties of this soil. The properties of lithomargic soils were improved by various additives such as chemicals, mechanical reinforcement, and a combination of chemical and mechanical methods, and with the use of biopolymers and bio-enzymes. Bio-enzymes are eco-friendly in nature and exhibit a good soil stabilization effect by forming bond between clay mineral and polar end groups of bio-enzymes, and reduces air voids. In this present study, TerraZyme is used as a lithomargic soil stabilizer and the compaction, strength, durability, and performance of a soil- TerraZyme mixture are reviewed.
Concrete is the most commonly used construction material in the entire world. However, deterioration of cement made structures are unavoidable right from the very beginning of service life, accompanied by maintenance and repair work, which is frequently labor-intensive and capital-intensive. During the 20th and 21st centuries, concrete was used widely worldwide as a building material. One of the significant signs of concrete technical advancement and overall quality growth is the rapid production of ready-mixed concrete, but there are some new issues. The most prominent issue is the higher likelihood of cracking caused by non-load factors, such as shrinkage cracks, thermal cracks and chemical reaction cracks, due to low concrete tensile strength. Cracking raises the probability of ingress of aggressive substances into the concrete, endangering the material's durability. Usually, Cracks are hand- mended, which is unsatisfactory because cracks are often difficult to find, and the cost of maintenance and repair is high. Self-healing of cracked concrete will also be extremely beneficial, and research on self-healing concrete has been extensively carried out.
