... strength is studied. Compressive strength, ultrasonic pulse velocity, permeability and flow table tests are also performed. Findings The paper’s findings are highlighted as follows: (1) strong mortar-mortar bond properties achieved for geopolymer mortar in all tests and conditions and validated...

... in Penang, Malaysia was selected as the case study. The level of permeability and wayfinding were determined in the building plan and were illustrated using photoshop software to depict the interrelation between the indoor spaces and building circulation. Graphs of the depth of space were used to analyze...

..., for both sand and gravel, compared to the control sample. Crushed and graded sea shells used in concrete displayed a lower porosity/permeability than plain concrete. Originality/value – Whilst there is existing work relating to the compressive strength of concrete using sea shells, the porosity...
