Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...

This paper considers the issues of improving strength characteristics foundations by injecting specially selected composite mortars into soils. The properties injection used in seismic hazardous areas are improved using various additives consisting wastes. article explores possibility a mortar modified with sulfur, which is waste from oil refining. influence its addition on materials studied. o...

This study used two types of Recycled Concrete Aggregates (RCAs) with the same original virgin aggregate, but with different amounts of residual mortars. To verify that the mechanical properties of the concrete were affected by changing the unit volume of residual mortar, fresh mortar, and total mortar of the concrete, a series of paving concrete mixes were made using a modified equivalent mort...

The size dependence of flexural properties of cement mortar and concrete beams is investigated. Bazant's size effect law and modified size effect law by Kim and Eo give a very good fit to the flexural strength of both cement mortar and concrete. As observed in the test results, a strong size effect in flexural strength is found in cement mortar than in concrete. A modification has been suggeste...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

sol-gel derived sulfur modified and pure zno nanorod were prepared using zinc chloride and thiocarbamide as raw materials. prepared nanorods were characterized by means of x-ray diffraction (xrd), thermogravimetry- differential scanning calorimetry (tg–dsc), uv- vis absorption spectroscopy, brunauer emmett teller (bet) specific surface area and barrett joyner halenda (bjh) pore size distributio...

Ceramic fiber, with a major composition of Al₂O₃ and SiO₂, has advantages of stability at relatively high temperature, big specific surface area and resistance to external mechanical vibration. It has the potential contribution of improving the rutting resistance and temperature sensitivity of modified asphalt binder by proper modification design. In this research, ceramic fiber was introduced ...
