Journal ArticleDOI
Use of microorganism to improve the strength of cement mortar
TL;DR: In this paper, a thermophilic anaerobic microorganism is incorporated at different cell concentrations with the mixing water, and a 25% increase in 28 day compressive strength of cement mortar was achieved with the addition of about 105 cell/ml of mixing water.
Journal ArticleDOI
Microbial activity on the microstructure of bacteria modified mortar
TL;DR: In this paper, the authors investigated the effects of incorporating a facultative anaerobic hot spring bacterium on the microstructure of a cement-sand mortar and found that the bacterial treatment promoted uniform distribution of silicate phases and increased the calcium/silicon ratio within CSH gel of the matrices.
Journal Article
Development of bioconcrete material using an enrichment culture of novel thermophilic anaerobic bacteria.
TL;DR: An attempt has been made to develop bioconcrete material incorporating of an enrichment culture of thermophilic and anaerobic bacteria within cement-sand mortar/concrete, showing a significant increase in compressive strength of both cement- sand mortar and concrete.
Journal ArticleDOI
Bioremediase a unique protein from a novel bacterium BKH1, ushering a new hope in concrete technology
Mousumi Biswas,Sudipta Majumdar,Trinath Chowdhury,Brajadulal Chattopadhyay,Saroj Mandal,Umesh Chandra Halder,Shinji Yamasaki +6 more
TL;DR: A novel hot spring bacterial strain was isolated and characterized from Bakreshwar, West Bengal, India and its unique protein both increase the compressive and tensile strengths, hardness and elastic modulus of cementitious material when incorporated to the cement/cement–sand mixture.
Journal ArticleDOI
Anti-microbial efficiency of nano silver–silica modified geopolymer mortar for eco-friendly green construction technology
Dibyendu Adak,Manas Sarkar,Moumita Maiti,Abiral Tamang,Saroj Mandal,Brajadulal Chattopadhyay +5 more
TL;DR: In this article, a silver-silica nano composite based geopolymer mortar has been developed by simple adsorption of silver in a suitable amount of a colloidal silica suspension for anti-bacterial property development.
