this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

Concrete with cactus is a new type of concrete high fluidity, strength, and durability more remarkable advantages. The present paper discusses the role Euphorbia tortilis (ETC) to achieve durability, corrosion resistance properties specimens. In this work, M20 (2900psi) was designed as per Indian standards, were used an additive. ETC extracts from Tamilnadu (India) replaced water (1%, 3%, 5%, 7...

The efficient utilization of robotic construction structures requires a review structural material, elements and details, while traditional methods face difficulties in producing some dry concrete joints, can manufacture them efficiently. With the rapid advancement new methods, more effort should be directed towards developing types joints manufactureable by Additive Manufacturing (AM) methods....

This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. Effects of wax in crude oil, bitu...

Attempts should be made to recycle, re–use and utilize waste. Paper manufacturing is a complex industry involving multiple processes where different products are produced and large quantities of waste of primary, biological or de–inking origin are generated, waste water treatment sludge, primary sludge, and secondary sludge among them.1,2 The primary sludge is generated in the largest quantitie...

todays applying concrete structures is more usual than other structures which are used in buildings as in most of the world’s countries the application ratio of concrete to steel has increased from 10 to 1. sometimes these structures require strengthening vulnerable members because of deficiency in their loading system in usual and critical conditions. there are different methods for strengthen...

With time, the development of micro-cracks in concrete is a frequently reported problem structures due to ingress harmful substances, leading degradation its quality and strength, which ultimately declines construction. The present work review paper based on enhancing self-healing property by inducing different bacteria alone or incorporating mineral additives. It has been seen that various reh...

Pyriproxyfen, a juvenile hormone analog insect growth regulator (IGR), is a recommended insecticide for the control of container-inhabiting mosquitoes. The effects of eight container substrates (three plastics, wood, tire rubber, clay pot, concrete, and glass) were studied on reduction of bio-efficacy of pyriproxyfen for Aedes albopictus (Skuse) in the laboratory. Insect growth regulator-bioass...

Attentive monitoring and regular repair of concrete cracks are necessary to avoid further durability problems. As an alternative to current maintenance methods, intrinsic repair systems which enable self-healing of cracks have been investigated. Exploiting microbial induced CaCO3 precipitation (MICP) using (protected) axenic cultures is one of the proposed methods. Yet, only a few of the sugges...
