Development of an anchorage prototype for CFRP stress-ribbon systems using 3D printing technique
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Compared with other structure types, stress-ribbon systems are extremely simple though requiring massive anchorage blocks because of very large tensile stresses induced in the ribbons. Such structural systems are efficient ... -
Effect of aggregate particle shape and granulometry on the workability and mechanical properties of glass reinforced concrete
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Modern alkali resistant glass fibers (ARG) modified with 17% ZrO2 are getting more popular as reinforcement of cementitious matrixes. Typical matrix compositions with quartz, Portland cement, 13 mm length ARG glass fibres ... -
The effect of concrete creep on the long-term tension-stiffening law and prediction of a time-dependent inertia moment of the cracked RC flexural cross-sections
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)In the paper, a long-term stress-strain model is proposed for predicting the deformational response of the cracked reinforced concrete beams subjected to sustained bending. The linear and non-linear evolution creep strains ... -
The effect of glass powder on physical and mechanical properties of hardened cement paste
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The article analyses the effect of finely crushed glass on the properties of hardened cement paste. Materials used for the test: Portland cement CEM I 42.5 R, finely crushed glass (particle size ≤75 µm), and water. Seven ... -
Evaluation of physical and mechanical properties of fired-clay bricks incorporating both mineral and organic wastes
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The clay brick is one of the oldest building materials, and as the use of waste in the bricks can reduce clay consummation and the environmental burden due to the accumulation of waste, the present study was chosen, the ... -
Experimental study of the behaviour of cement pastes in the presence of carbon nanotubes
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)One of the methods recently applied for the noticeably improvement of properties of cementitious materials is the use of the single or multi-walled carbon nanotubes (CNTs) as nano-reinforcements in cementitious materials. ... -
High strength steel cold-formed hollow sections: implication of cross-section aspect ratio and slenderness characteristics on flexural behavior
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Cold-formed tubular sections are widely applicated for a variety of structural solutions, primarily due to their advantageous structural properties, inherent aesthetic characteristics and ease of prefabrication and mass ... -
High-strength fluoroanhydrite composition
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)The research studies the properties of a high-strength anhydrite composition based on fluoroanhydrite, a waste product of hydrofluoric acid. To activate fluoranhydrite, Na3PO4 sodium phosphate was added to the composition ... -
Internet of Things (IoT) for digital concrete quality control (DCQC): A conceptual framework
(International Conference Modern Building Materials, Structures and Techniques (MBMST 2019), 2019)Concreting is generally a manual, labour intensive and time-consuming process, putting additional burden on constrained resources. Current practices of concreting are wasteful, non-sustainable and end products usually lack ... -
