Superfine pigments that consist of natural and artificial pigments and are made of mineral soil with special characteristics are used in cementitious materials for various purposes. These pigments can decrease the amount of cement needed without loss of performance and strength and also change the monotonous and turbid colours of concrete into various attractive and light colours. In this study...
We outline the ability of zinc phosphate coatings, obtained by chemical conversion, to protect mild steel rebars against localized corrosion, generated by chloride ions in alkaline media. The corrosion resistance of coated steel, in comparison with uncoated rebars and coated and uncoated steel rebars embedded in mortar, were evaluated by open-circuit potential, potentiodynamic polarization, cro...
The present study aims to obtain the tensile properties of early age concrete based on a uniaxial tension test employing RC slender members. First, the paper shows that concrete strain is equal to the strain of rebar at the mid-span of the RC member. The tensile Young's modulus and the strain capacity of early age concrete are estimated using strain measurements. The experiment indicated that t...
Experimental testing of deformed rebar anchors (DRAs) has not been performed extensively, so there is limited test data to understand their failure behavior. This study aims expand upon these tests and the behavior anchors, when loaded in tension. Analytical benchmark models were created using available a parametric was performed. Anchor diameter, spacing, embedment, number varied for total 49 ...
Abstract Rock stress is causing unwanted deformations of deep underground spaces. Large increase the risk failure. The excavation causes rock changes in surrounding mass, and resulting can be measured. In this paper, we present a method to monitor mass using rebar bolts instrumented with strain gauges track within bolt. Next that, describe in-situ testing heating-induced natural environment. he...
It is important to apply the Length types of Processed Rebar Simplification (LPRS) rebar work for improving efficiency and reducing labor in construction fields. However, when used excessively, LPRS can also bring about adverse results, as increase amount wasted rebars scale with cutting process, leading an material cost. Therefore, it crucial find a proper level simplification considering cost...
