RISShear Behavior of RC Beams with Corroded Stirrups Strengthened Using FRP Laminates: Effect of the Shear
Publisher: ASCE
Abstract: Externally bonded reinforcement fiber-reinforced polymer (EBR FRP) laminates have been used around the world for the shear strengthening of reinforced concrete (RC) beams with corroded stirrups. The shear span-to-depth ...
Binding Mechanism of CSA Cement on Premixed Cl− and Its Governing Parameters
Publisher: ASCE
Abstract: Calcium sulfoaluminate (CSA) cement showed a good binding capacity on the external Cl− transported into concretes from its surrounding environment. However, it is unclear whether the same binding mechanism can still apply ...
Durability of Slag–Cement Paste Containing Polyaluminum Chloride
Publisher: ASCE
Abstract: The effect of polyaluminum chloride (PAC) on the durability, microstructure, and corrosion sensitivity of slag–cement pastes was investigated in this research. Various experimental tests were performed to assess the ...
Effects of Seawater, NaCl, and Na2SO4 Solution Mixing on Hydration Process of Cement Paste
Publisher: ASCE
Abstract: The use of seawater as mixing water for concrete production is one of the most efficient strategies to solve freshwater shortage problems. The purpose of this paper is to investigate the effects of seawater mixing on ...
Behavior and Modeling of Hybrid CFRP/Steel Reinforced Concrete Beams with Cathodic Protection in a Marine Environment
Publisher: ASCE
Abstract: Impressed current cathodic protection (ICCP) has been proven to be an effective technique to inhibit steel corrosion. Based on the principle of ICCP, a hybrid carbon fiber–reinforced polymer (CFRP)/steel reinforced concrete ...
Mechanism Analysis on Carbonation of Hardened Cement Paste with XCT
Publisher: ASCE
Abstract: X-ray computed tomography (XCT) was used to monitor microstructure changes of hardened cement paste, with different water/cement ratios during a one-dimensional carbonation process. After removing equipment-induced measurement ...
Effects of Calcium Sulfate on Performances of CSA Clinker-Premixed Cl− System: Chloride Binding Analysis
Publisher: ASCE
Abstract: Calcium sulfoaluminate cement (CSA) has excellent chloride (Cl−) binding capacity, which is significantly influenced by the existence of calcium sulfate within mixes. However, impacts of dosage and type of the calcium ...
Experimental Study on the Influence of Water Absorption of Recycled Coarse Aggregates on Properties of the Resulting Concretes
Publisher: American Society of Civil Engineers
Abstract: In this paper, three recycled coarse aggregates (RCAs) with different 24-h water absorptions (5.67, 3.12, and 1.98 wt%) were used to produce recycled coarse aggregate concretes (RCACs). Different water absorption rates ...
Construction of Concrete-Faced Rockfill Dams with Weak Rocks
Publisher: American Society of Civil Engineers
Abstract: Constructing concrete-faced rockfill dams (CFRDs) with weak rocks has great advantages as a result of the use of local materials, cost-effectiveness, extensive adaptability, simple construction, and short construction ...
C-FRCM Jacket Confinement for RC Columns under Impressed Current Cathodic Protection
Publisher: ASCE
Abstract: In coastal regions, chloride penetration causes steel reinforcing bar (rebar) corrosion in reinforced concrete structures, leading to durability problems in existing structures. A new intervention method, impressed current ...
