چکیده
The article presents studies’ results of cementless lightweight concretes based on porous granular aggregate. Lightweight concrete components are specially synthesized from mixtures containing liquid sodium glass and thermal energy waste with various fineness. Thermal hardening a matrix technogenic fillers at temperature 350ºС provided heat-insulating 480 kg/m 3 density compressive strength 4.7 MPa. aim the work is to study operational stability genetically related components. Durability was evaluated in terms hydro physical properties, resistance frost salt aggression, cyclic heating. Methods mechanical testing have been used work. X-ray phase analysis electron microscopy were materials’ composition structure. complex tests showed structure aggregate impact factors. developed characterized by softening coefficient 0.81; they withstood 50 cycles alternating freezing thawing, 20 exposure 1050ºС 250ºС; staying aggressive sulfate chloride magnesium solutions.

Preparation and properties of porous aerated concrete
INTRODUCTION Porous concrete, especially Aerated Autoclaved Concrete (AAC) was first developed by a Swedish engineer between the years 1920 and 1932 [1]. He was searching for a material with the properties of wood, but without the disadvantages of wood. Near the end of World War II, AAC became widely used. Vast areas of cities and industries lay in waste and tremendous rebuilding became necessa...

Glass Fibre Reinforced Concrete is recent introduction in the field of concrete technology. The present day world is witnessing the construction of very challenging and difficult Civil Engineering Structures. Concrete being the most important and widely used material is called upon to possess very high strength and sufficient workability properties. Concrete the most widely used consrtuction ma...
متن کاملInvestigating the Properties of Asphalt Concrete Containing Glass Fibers and Nanoclay
The performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. Therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. One common method of improving the performance of asphaltic mixtures is using different types of ...
متن کاملExperimental Investigation of Behavior of Glass Fiber Reinforced Concrete (GFRC)
The paper presents the results of casting and testing of 264 GFRC specimens. The glass fibers were 25 mm long, with the aspect ratio (L/D) ranging between 1250 and 3570. The parameters studied were the ratio (by weight) of fibers to cement, i.e. F/C=0%, 1.5%, 3%, and 4.5%, and the ratio of coarse to fine aggregates (gravel to sand), i.e. G/S=1.1, 0.7 and 0.2. In total, 12 mix designs were selec...
