Abstract Simulation of heavy oil thermal cracking process is very important but few researches have been published now. In this paper, a simulation framework based on the carbon number-based approach(CNCA) has been established. A systematic division rule is put forward for dividing cracked products into 59 carbon number components. Then the cracking reaction network has been structured and the ...

Abstract We report the outcomes of a study into influence alkali concentration on expansion induced by alkali–silica reaction (ASR), deleterious that causes cracking and durability loss in concrete structures. assessed effect mortar bar using modified form AS1141.60.1, accelerated test (AMBT). Mortar prisms were prepared with reactive aggregate immersed solutions varying concentrations (from 0....

analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...

Given that concrete masonry walls are expected to experience shrinkage combined with thermal expansion and contraction, and in some cases even carbonation, throughout their service life, cracking is to be expected. However, after concrete masonry walls have been placed into service, originally anticipated and accounted for cracking is often misdiagnosed as a structural defect. Such misdiagnoses...

Though many diagnostic PCR methods have been described, few techniques have been developed to rapidly and efficiently screen transformed bacterial colonies for plasmid presence (1). Unfortunately, PCR screening of a large number of colonies is time consuming and requires substantial amounts of polymerase and primers. In this report, we describe a two-step large-scale bacterial colony screening ...

The use of geopolymer in pavement constructions is strongly encouraged. Many studies have demonstrated the vast potential using industrial-by-products-based geopolymers. This paper discusses modification asphalt binders with geopolymers, namely geopolymer-modified (GMA) and mixture (GMAM). In addition, curing materials, engineering properties, production techniques, prospective utilisation cons...

The technological process for manufacturing seamless steel tubes in the Sisak Rolling Mill includes the heating of the charge for processing in the hearth-rotating furnace. Description of the furnace and its operation can be found in literature 1 . In the process currently applied for producing the tubes with the outer diameter of 168.3–356.6 mm the temperature is between 1280 and 1300 °C 2 . T...

The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...
