Hossein Khosravi; Atefeh Adelian Haghighi

Volume 5, Issue 8 , October 2023, , Pages 26-37

https://doi.org/10.22034/cpj.2024.436277.1254

Abstract
  The concrete-filled double skin steel tubular columns (CFDST) are regarded as one of the composite columns consisting of double steel tubes with square or circular hollow sections and the space between two skins is filled with concrete. These columns possess several advantages, including a proper performance ...  Read More

Simulation the Effects of Fiber on the Poisson's Ratio of Self-Compacting Concrete

HAMOON FATHI; Mohammad Yousefinezhad

Volume 5, Issue 7 , October 2023, , Pages 38-46

https://doi.org/10.22034/cpj.2023.419946.1223

Abstract
  The present paper studies experimental research on the effects of fiber on the strain and the Poisson's ratio of self-compacting concrete (SCC). The experiment was carried out on 48 cubic concrete samples and 68 standard cylindrical samples of 4 different mixes with compressive strengths of 25, 28, 30, ...  Read More

Evaluating the Mechanical Properties of Self-Compacting Concrete with Rubber Additives (Case Study: Shiraz Mind)

AliMohammad Sazegar; roozbeh aghamajidi; mehdi rezaei

Volume 4, Issue 7 , October 2022, , Pages 50-58

https://doi.org/10.22034/cpj.2023.379979.1169

Abstract
  The use of rubber crumb as an additive in the production of concrete has been studied as a means of improving compressive strength while also addressing the environmental impact of non-degradable ingredients. In this research, the effects of adding 5%, 7.5%, and 10% rubber crumb by weight to 2% cement ...  Read More

Evaluation of the effect of polyurethane paint on mechanical properties and durability of self-compacting concrete containing methaacolene and microsilica

Mohammad Reza Asadi

Volume 1, Issue 3 , August 2019, , Pages 39-56

Abstract
  The importance of using concrete as the main material in the construction of structures seems obvious. Due to the high cost of repairs, their durability is of particular importance. Permeability is the most important factor in reducing the durability of structures so that resistance to concrete permeability ...  Read More

Investigation of compressive strength and permeability in self-compacting concrete with and without polyurethane paint

Mohammad Reza Asadi

Volume 1, Issue 3 , August 2019, , Pages 68-79

Abstract
  The purpose of this study was to investigate the compressive strength and permeability of polyurethane-containing and non-dyed concrete containing methacrylene and silica. The compressive strength of all designs increased with increasing age of concrete compared to the control. As the percentage of nanosilica ...  Read More

Evaluation of the effect of polyurethane paint on the properties of self-compacting concrete containing methaacolene and silica to accelerated chlorine ion penetration

Samira Shokati Gourabi

Volume 1, Issue 3 , August 2019, , Pages 80-89

Abstract
  The importance of properly evaluating the strength of the concrete against the penetration of chlorine ions to achieve durable structures is highlighted. Different laboratory methods have been developed to determine the phenomenon of migration and diffusion of chlorine ions into the concrete mass. In ...  Read More
