Concrete Mix Design by IS, ACI and BS Methods: A Comparative Analysis DOI:  https://doi.org/10.30564/jbms.v2i1.2636 Abstract Concrete is one of the most consumable construction materials on the earth. The concrete constitutes cement, sand, gravel, water and/or additives in definite proportions. The proportions of raw materials of concrete are decided by the concrete mix design. The mix design depends on the various factors. For mix design, most of the countries have their own specifications. In the present study, standard guidelines of India, Britain and America for the concrete mix design have been discussed. The concrete grades of M25, M35 and M45 were designed and compared. Indian Standards were also compared. It was concluded that new revised version of Indian Standard code has the lowest value of water/cement ratio and highest quantity of cement as compared to other standards. Keywords:  Concrete, mix design, Indian Standards, ACI code, BS code

Photon and Fast Neutron Transmission Parameters of Metakaolin Doped Concrete DOI:  https://doi.org/10.30564/jbms.v3i2.3817 Abstract Radiation-shielding properties of metakaolin doped concrete samples wereinvestigated in this report. The gamma photon mass attenuation coefficientsand exposure buildup factor of the samples were determined theoreticallyusing WinXcom and EXABCal software respectively for the energyrange of 15 keV - 15 MeV and fast neutron removal cross section for theconcrete sample was evaluated. Results indicated that, oxides of silicon,aluminum, calcium and iron determined through the energy dispersiveX-ray fluorescence spectrometric analysis constitute more than 85% ofthe chemical composition of the concrete samples. The oxides contribute85.46, 86.47, 87.55, 88.75, and 86.15 % of the total chemical oxides inMK00, MK05, MK10, MK15, and MK20 respectively. Densities of theprepared MK doped concrete were in the range of 2.575-2.667 g/cm3 .Compressive stress of prepared ...

Hemp Concrete: A Sustainable Green Material for Conventional Concrete DOI:  https://doi.org/10.30564/jbms.v3i2.3189 Abstract Concrete is one of the most important building material and day by day theutilization of concrete is increasing to meet the infrastructure developmentrequirement. On one hand it is unavoidable but some alternative to beexplored to reduce the global environmental impact caused by the concrete.To overcome this from the last decade the world is looking towards thefact of sustainability due to rapid industrialization. The growth in theconstruction industry increased the demand of concrete as constructionmaterial. This concrete produces significant amount of greenhouse emissionin the environment. There is a need to find an alternative solution tominimize the greenhouse emission emitted from the concrete manufacturingplant.Hempcrete is a building material prepared from hemp yarns, lime andwater. This composite material has several beneficial properties like lowin c...

Properties of Sawdust Concrete DOI:  https://doi.org/10.30564/jbms.v4i2.4818 Abstract This work examined the structural properties of concrete obtained bypartially replacing cement with sawdust ash. The sawdust ash which is apozzolan was obtained by burning sawdust which is a waste product fromprocessing of timber in an open air. The burnt ash was passed through a150 µm metric sieve to obtain the ash used. Physical and chemical analysiswere performed on the ash to verify its suitability as a partial substitute forcement in concrete. Chemical analysis was also carried out on the OrdinaryPortland Cement (OPC) sample. Concrete mixes were produced by replacing OPC with 0%, 5%, 10%, 20% and 30% of Sawdust Ash (SDA). Bothfresh and hardened properties of the concrete produced were investigated.The chemical investigation on the ash showed that it contained most ofthe basic compounds found in OPC making it suitable to serve as a partialsubstitute for OPC in concrete. Investigation on the co...
