Masonry wall construction

Abstract The rapid growth of contemporary construction industry has driven engineers to explore new construction techniques for sustainable development. Interlocking block wall construction reduces time, labour and enhances construction efficiency compared to conventional masonry wall construction. The interlocking pattern has been applied to the top and bottom surface of block to withstand gravity and lateral loads whereas current interlocking blocks only serve the purpose of easy alignment. In this study, eco-friendly blocks have been developed with industrial waste such as fly ash, quarry dust and geopolymer as binder. Tests to evaluate the compressive strength, water absorption and efflorescence have been carried out on both traditional and geopolymer interlocking blocks. Later, on two blocks joint, in-plane vertical load has been applied and the same model is generated to validate the failure. Using numerical modelling, horizontal and vertical load resistance of interlocking block wall and traditional brick wall was compared. The experimental results show that, relative to traditional clay brick, the compressive strength of the geopolymer interlocking block was high but the absorption of water was low. The vertical load resistance is identical but horizontal load resistance was high in interlocking block wall. The interlocking geopolymer block was the best approach for environmental sustainability.

Fire Spreading

Fire exposure of a construction represents an accidental load (temporary with a high intensity) and it´s appearance during service life of the construction is improbable. All structural eurocodes, which deal with the normal temperature (20°C) design of structures made from loadbearing materials (steel, steel and concrete composite, concrete, masonry and timber), include always Part 1-2: Structural fire design. Concrete, similar to the masonry, has (in comparison with other construction materials such as steel and timber), an excellent resistance against fire exposure. This is why both of these materials are used for construction of fire walls, which create barriers against the fire spreading. Fire walls separate two spaces and they are designed for fire resistance and structural stability, including resistance to mechanical impact. In the case of fire and failure of the structure on one side of the fire wall, fire spread beyond the wall is avoided. Properties of concrete and masonry walls, subject to fire exposure, are however negatively influenced. Concrete compressive strength is reduced depending on the aggregate choice. The strength of reinforcing bars is also reduced at elevated temperature, by an amount which strongly depends on the axis distance of the reinforcing bars from an edge of a cross section, too. The behaviour of a masonry wall depends on a masonry unit type and material, type of the mortar, the density of units, type of the wall construction, and applied surface finishes. In the present article we discuss basic principles of the design and assessment of various concrete and masonry fire walls and compare their effect - fire resistance period – depending on their thickness.
